▼ Cissampelos capensis L. f. (Menispermaceae) commonly known as “Mayisake” (Xhosa) and “Dawidjieswortel” (Afrikaans) is the most commonly used medicinal plant of the Menispermaceae family in South Africa. The rhizomes of Cissampelos capensis are the most used part of the plant to treat illnesses. This poses a threat to the ongoing conservation of this valuable endemic species. Thus, we studied the chemical variation and subsequently the bioactivity in the stems and rhizomes of Cissampelos capensis, the Eastern Cape medicinal plant, to suggest the possible use of the stems for medicinal purposes. We studied the variation in the chemical composition in the stems and the rhizomes by employing four different extraction methods; the methanolic-, non-polar-, alkaloidal- and Total Tertiary Alkaloidal (TTA) to extract compounds from Cissampelos capensis. Employing various chromatographic techniques, HPLC, NMR and LC/MS to investigate the chemical variation and the in vitro assays for the crude materials of the stems and rhizomes of Cissampelos capensis. We successfully documented a library of the phytochemicals content in Cissampelos capensis from three different regions in the Eastern Cape. We could profile different extraction methods, with the TTA extraction delivering the best comparative profile. Employing LC/MS and HPLC we identified eleven known alkaloidal compounds in the stems and rhizomes. We also isolated a known alkaloid, pronuciferine, from the TTA extract and a crystal structure of proto-quericitol from the methanolic extract, which was isolated for the first time from Cissampelos capensis. Preliminary in vitro results suggested anti-inflammatory activity in the methanolic extracts of the stems and rhizomes, while the TTA extracts showed some cytotoxicity. Finally, through analytical HPLC analysis this study found as high as 31% similarity between the chemical variation of the stems and rhizomes, but key alkaloids were not always present, indicating more work is needed before the stems can be recommended as a replacement for the rhizomes.

▼ Green houses provide opportunity for year round crop production. Although tomatoes are an option for utilizing greenhouse space, performance of tomato under these conditions has potential limitations which may include root restriction and its attendant impacts such as artificial media effects on varietal characteristics. Decline in profitability of rose production for which greenhouses in Zambia were used has left excess capacity. Tomatoes provide a profitable option for farmers. A study was conducted was to evaluate growth responses of tomato grown in different growing media under controlled environment (greenhouse) and Field conditions of three tomato varieties (Star 9030, Tengeru and Rodade) under different growing media (Peat in sleeve, Coccus in sleeve, Coccus in trough, Soil in sleeve and Soil bed). The experiment was conducted at the Natural Resources Development College in Lusaka between May to October 2011. Two experiments were carried out; the first one was a Greenhouse study under an open sided naturally ventilated Plastic greenhouse. The experimental design adopted was a Split plot design where, varieties were assigned to the main plots and the media to subplots. The field experiment involved the same varieties planted directly into the soil but used a Randomized Complete Block Design. The parameters measured included vegetative variates i.e. plant height and root/ canopy ratio; reproductive variates were; total fruit number per plant and total yield. Fruits were harvested at breaker stage when the skin colour was 30% pink red. Fruit quality parameters including shape (indicated by the ratio of fruit diameter to height) and Brix (Total soluble solutes content). The results from the study showed that: In the greenhouse Star 9030 grown in soil bed grew taller than the other 2 varieties. The trend of these results was significant from 4 weeks after transplanting. The total fruit number and weight of Star 9030 grown in soil bed (29 and 19.5t/ha) was significantly higher than Rodade (14 and 8t/ha) and Tengeru (24 and 15t/ha) compared to other media (p ≤ 0.001), whilst the root: shoot ratio was not significant different among the cultivars and media. The total soluble solid content expressed as Brix was significantly different between varieties, Tengeru with 5.0 was highest followed by Star 9030 with 4.0, Rodade with 3.5. ). Fruit diameter: height ratio was not different between Rodade and Tengeru but significantly lower than Star 9030 whilst the effect of media showed no significant differences. In comparison to the greenhouse results, the field experiment performance was as follows; the mean fruit weight was; Star 9030 (12 t/ha), Rodade (5 t/ha) and Tengeru (10 t/ha) whilst total soluble content at 4.7 for Star 9030, 3.5 for Rodade and 3.7 for Tengeru was not significantly different among the different varieties .

▼ Abstract provided by author; Invasive alien species (IAS) are non-native species that cause, or have the potential to cause, harm to the environment, economies, or human health. The threat to biodiversity due to invasive alien species is considered second to that of habitat loss. The focus of the study was on one of the invasive alien plant Datura innoxia. The study was conducted in the City of Windhoek, the capital of Namibia, situated at 22.56°S, 17.09°E; The aim of the research project was to study the distribution, abundance and reproductive status of the invasive alien D. innoxia in the City of Windhoek. The information gathered will contribute to the knowledge and understanding of weedy invasive aliens in the City; Data was collected 121,25 0000 m2 grids that were randomly sampled in the City. The City of Windhoek grided map was used to locate the specific grids. The grids were sub-divided into sixteen 15625 m2 plots to ease observations. In each plot, all D. innoxia were recorded including their height, crown width, number of capsules and number of flowers. Within a radius of one-meter, other organisms and plants associated with D. innoxia were also recorded. The presence and absence of other plant species found in the plots were recorded. ArcView 3.2 was used to develop the distribution map and SPSS 15 was used to analyze the data; The study revealed that D. innoxia is widely distributed along riverbanks, disturbed areas and around human settlement. A high infestation of D. innoxia was observed in the drainage lines and within the built-up areas. The occurrence of D. innoxia is influenced by the different types of activities and is associated with disturbances. The study also showed that D. innoxia is a perennial trailing or bushy herb plant with a continuous floral development with no significant difference (?2F (3) = 7, p0.05) in the number of D. innoxia in the different reproductive status within the geo-morphological landforms. However, there was a significant difference (?2F (2) = 5, p0.05) in the number of D. innoxia with the construction and no construction area and within the open spaces and built-up areas. Therefore, D. innoxia is a cosmopolitan opportunistic weed that is abundant in construction areas, drainage lines and around human settlements; The Hierarchical Cluster Analysis revealed that Acacia mellifera, Dichrostachys cinerea, Boscia albitrunca and Senecio windhoekensis were the dominant woody and herbaceous vegetation in all the clusters. The Cityof Windhoek is situated in the highland savanna vegetation, all the dominant species characterizing the highland savanna were present. Variation within the vegetation composition was attributed to the different land uses within the City of Windhoek and not to the presence of D. innoxia.

Summary: The aim of this dissertation was to explore structurally unique secondary metabolites from herb medicinal plants Cornus controversa and Delphinium chrysotrichum. The introduction in the first chapter provides a detailed review about the research progress of chemical constitutents of the genus Cornus. In addition, its pharmacological activities were also summarized in this chapter to provide a framework for understanding the roles of medicinal herbs belong to genus Cornus as anti-diabetes therapeutics and to deliver useful information for further research. In chapter two, seven new compounds, including one iridoid glucoside, cornoside A (59), five iridoid aglycones, cornolactones A – E (60 – 64) and one indenone glucoside, cornoside B (65), together with 10 known compounds have been isolated from the leaves of Cornus controversa. The structures of these compounds were established by interpretation of spectroscopic data. Cornolactone A (61) is the first natural cis-fused tricyclic dilactone iridoid containing both a five- and six-membered lactone ring. Cornoside B (65) is the first alkaloid isolated from the genus Cornus bearing an indole-3-lactic acid-11--D-glucopyranoside skeleton. In chapter three, we described the structure elucidation of three new diterpenoid alkaloids delphatisine D (77), chrysotrichumines A (78) and B (79), as well as 11 known compounds from the whole plants of Delphinium chrysotrichum. Delphatisine D (77) is a rare atisine-type alkaloid from genus Delphinium and is the C-15 epimer of spiramine C which bears an internal carbinolamine ether linkage (NCOC) between C-7 and C-20. Chrysotrichumine A (78) is a rare natural C19-diterpenoid alkaloid possessing a nitrone group between C-17 and C-19. In addition, their cytotoxic activity against human breast cancer cell lines of MCF-7 and MDA-MB-231 were also reported. In chapter four, the detailed extraction and isolation procedures of the new compounds, cornosides A and B, cornolactones A – E, delphatisine D, chrysotrichumine A and B, as well as of all the known compounds were described. In addition, the experimental procedures for the determination of PPARγ and LXR agonistic activities and the MTT cytotoxicity assay were listed in this chapter.

▼ The general aim of this thesis was to investigate the mechanisms that determine variation in Al accumulation among tropical woody plants. The focus of the study variation among populations of the well-studied Al accumulator Melastoma malabathricum, but this was coupled with sampling 50 tree species growing on the 50 ha forest dynamics plot at Pasoh Forest Reserve in Peninsular Malaysia in order to gain a perspective on Al accumulation at a community scale. I sampled mature leaves and seeds of M. malabathricum from 20 populations growing in six habitats across Peninsular Malaysia. Concentrations of Al, N, P, K, Ca and Mg were determined in air-dried leaves and the soil from each site. The seeds were used to generate cohorts of seedlings that were grown in hydroponic solutions amended with Al in the form of 1.0 mM AlCl3. Foliar Al concentrations varied significantly among populations, but were not consistently different among plants growing in different habitats and showed no relationship to total or exchangeable Al concentrations in soils collected at the 20 sites. Similarly, foliar Al concentrations in seedlings grown in the presence of Al differed significantly among source populations, but values did not correlate with foliar Al concentrations in wild plants from parent populations. Mean foliar Al concentration in wild plants was positively correlated with foliar Ca concentration, and with total soil Ca and Mg concentrations, across the 20 populations. Furthermore, total dry mass and relative growth rates were significantly greater for seedlings that had received Al in the growth medium than for seedlings that had received no Al. The growth response to Al addition varied among populations of M. malabathricum, and relative growth rate in response to Al addition was greater for populations that accumulated higher foliar Al concentrations. In a further experiment, increasing Al concentrations from In a further experiment, increasing Al concentrations from 0 to 2.0 mM in the nutrient solution increased rates of growth, but growth declined at 5.0 mM Al. The responses to Al addition varied among populations for growth, photosynthesis, respiration, carbon allocation, and foliar P, Ca, and Mg concentrations. The rates of photosynthesis and respiration, and total nonstructural carbohydrate concentrations, were higher for seedlings grown in the presence of 2.0 mM Al in the nutrient solution than in the absence of Al, while lignin concentration in roots decreased. These results suggest that Al addition stimulate growth stimulation by increasing rates of photosynthesis and respiration, resulting in higher non-structural carbohydrate concentrations. Increased allocation of photosynthate to root systems coupled with their lower lignification results in enhanced nutrient uptake (particularly P, Ca and Mg), which contributes to enhanced whole-plant growth. To test the prevalence of Al accumulation at the community scale I sampled 50 tree species growing on the 50 ha Forest Dynamics Plot at Pasoh Forest Reserve in Peninsular…

▼ Epigenetic mechanisms are important for control of plant development, and may play a particularly important role in trees given their long life cycles and distinctive and stable tissue types. To help understand the role of epigenetics in tree development, we produced transgenic poplars with reduced activity of the DDM1 genes, whose activity are known to be critical for the maintenance of DNA methylation in plant genomes. DNA methylation is widely recognized as a major element of epigenetic variation, where its presence is usually associated with loss of gene expression. The DDM1 gene is necessary for the maintenance of DNA methylation in the extensive heterochromatic fractions of the genome. We identified two highly similar DDM1 homologs in poplar (PtDDM1) and used RNAi to suppress both of their transcripts with a single construct. PtDDM- RNAi transgenic poplars showed a wide range of suppression efficiency, with the most strongly suppressed gene insertion events (lines) having a reduction in RNA expression of 70% based on combined stem and leaf in vitro materials and real time RT-PCR. Six transgenic lines were analyzed for their total cellular cytosine DNA methylation by HPLC (High Performance Liquid Chromatography). The DNA methylation percentages were generally correlated with PtDDM1 expression. A greenhouse study identified variation in growth rate associated with events, but these were not associated with PtDDM1 gene expression. There were also no visible differences in morphology of the transgenic lines. However, after dormancy, transgenic trees with strong PtDDM1 suppression that were growing out of doors in a covered "lathouse" showed a severe mottled leaf phenotype in all of its ramets, and two other transgenic events with strong PtDDM1 suppression showed similar but less severe symptoms in some of their ramets. A study of in vitro callogenesis of stem explants showed an inverse correlation between DDM1 expression and the percentage of rapidly growing callus; however, these results were not repeated with leaf explants or in a second experiment with a different experimental design. The second study showed a positive correlation between PtDDM1 expression and callus size. We speculated that the reduced methylation promoted tissue dedifferentiation, redifferentiation, and cell division, and that the mottled leaf phenotype was a result of DNA methylation change in the poplar genome. Our results suggest that transgenic demethylation may be a useful tool for promoting in vitro regeneration, but requires considerably more study of different target genes and suppression methods.

▼ Plants have always been a source of medicine and are still being used by traditional healers in the rural part of Africa, Asia and India to treat a range of illnesses including cancer. The in vitro anticancer activity of an 80 percent ethanol extract of Cyathula prostrata, an annual branching shrub used by traditional healers in Nigeria to treat cancer was investigated. No previous studies have outlined the possible pathways and mechanisms used by cancer cells when treated with C. prostrata. Dose response analysis was performed to determine the effective cytotoxic concentrations of C. prostrata on HeLa (cervical cancer cell line) and U937 (myelo-monocytic cell line). The IC50 values were 100.8 μg/ml and 64.4 μg/ml for HeLa and U937 cells, respectively. All further experiments were performed using 125 μg/ml C. prostrata extract and 50 μM cisplatin as positive control. With the use of the fluorescent DNA binding dye propidium iodide, the induction of tumour cell death by C. prostrata extract has been linked to cell cycle arrest in the G1 phase at 24 and 48 h. In both cell lines, more than 80 percent of the C. prostrata treated cells were found in the G1 phase after 48 hours of treatment. The annexin V-FITC/PI assay revealed an increase in the percentage apoptotic cells from 4.9 percent to 53.1 percent at 24 h and 8.3 percent to 50.3 percent at 48 h. Since apoptosis induction can occur via a number of different pathways, distinct features were used as markers to investigate the mode of action of this C. prostrata extract. Markers such as activated caspase-8, p21 and cyt-c, were investigated with the aid of fluorescently labelled (FITC) antibodies with analysis using flow cytometry. No change in p21 levels was observed in response to treatment with the extract for up to 48 h. Cell cycle arrest in G1 was therefore not induced by this cyclin-CDK inhibitor. Increase in caspase-8 activation was observed in response to treatment with the extract with no cyt-c release from the mitochondria. The lack of cyt-c release was due to no change in mitochondrial membrane potential, which was investigated with the aid of fluorescent mitochondrial dyes and flow cytometric techniques. Caspase-8 activation is unique to the extrinsic apoptotic pathway. The results from this study therefore show that C. prostrata extract induces apoptosis via the extrinsic pathway and that this activation in independent of the mitochondria. The levels of hTERT, the catalytic subunit of telomerase, were investigated as an additional molecular target for C. prostrata. This was also investigated using FITC labelled antibodies and flow cytometry. A decrease in hTERT levels was observed following C. prostrata treatment. The findings from this study suggest that the extract acts through multiple targets, by inducing: cell cycle arrest in the G1 phase through an unknown mechanism; apoptosis through an extrinsic death receptor pathway and replicative senescence through inhibition of telomerase.

▼ Growth of lettuce may be limited in acid soils by manganese toxicity which may be alleviated by applications of lime, phosphate fertilisers, iron and molybdenum. However few investigations have been undertaken to determine the biochemical effect of excess manganese in plants. The aim of this project was to demonstrate that manganese toxicity could reduce lettuce yield by inhibiting nitrate reductase activity. Manganese toxicity inhibited nitrate reductase activity in lettuce plants grown in an acid krasnozem soil. The yield of affected plants, which was significantly lower than the yield of control plants, was significantly correlated with the decrease in nitrate reductase activity. Associated with the decrease in nitrate reductase activity was an accumulation of nitrate in leaves and a decrease in the total nitrogen content (mgN/plant). Following applications of molybdenum foliar sprays there were significant increases in yield and nitrate reductase activity. The molybdenum content of plants increased in plants which had high tissue levels of manganese. The increase was probably due to the lower yield in these plants. It is not known how molybdenum reverses the manganese inhibition of nitrate reductase. Similar responses were observed in lettuce grown in nutrient solution. The Critical solution concentration of manganese,at which there was a decrease in yield and in nitrate reductase activity, was found to be 36uM. Nitrate reductase activity of young and mature leaves was significantly correlated with leaf manganese levels. Plants grown in nitrate-nitrogen nutrient solutions were more susceptible to manganese toxicity than plants grown in ammonium nitrogen nutrient solutions. A study of the time-course of manganese inhibition of nitrate reductase in vivo (indicated that after a short lag period, manganese significantly decreased nitrate reductase activity. The half life for this decrease in enzyme activity was found to be 2.5 hours. These results indicated that manganese was not inducing molybdenum deficiency and that manganese may have inhibited nitrate reductase by binding to the enzyme. Enzyme kinetic analysis of the manganese inhibition of nitrate reductase (in vitro) showed that manganese was a competitive inhibitor of nitrate reductase with respect to NADH and a non-competitive inhibitor of nitrate reductase with respect to nitrate. These results indicated that manganese was bound to the enzyme at or near the binding site for NADH. When manganese was added to the enzyme before NADH the degree of inhibition was greater than when the NADH was added to the enzyme before manganese. These results also indicated that manganese was interfering with the binding of NADH to the enzyme. EPR studies supported the results obtained with the kinetic analysis of the inhibition of nitrate reductase. Results of the EPR study showed that manganese was not bound by NADH but could be bound by the partially purified enzyme extract.

▼ Tomato aspermy virus (TAV) was found infecting more than 90% of chrysanthemum plants collected from several gardens in the Hobart district. The virus is readily transferred by sap inoculation to tobacco (Nicotiana tabacum var. Hickory Prior) in which it causes a severe systemic disease, and real relative concentrations of infective particles in tobacco plants can be measured reliably on Chenopodium amaranticolor, a local lesion host, if certain procedures are adhered to. Tobacco plants may be freed from infection by growing them at a constant temperature of 36 C for between 5 and 30 days. The percentage of cures effected is generally greater if cuttings are taken from plants immediately after treatment and rooted in a mist propagation unit. A decreased rate of viral synthesis is one reason for the effectiveness of the method. Under normal conditions of heat treatment, virus multiplication could never be detected although some indirect evidence, from results with cytokinin applications to treated plants, suggested that limited multiplication still occurred. However, measurable synthesis did take place if heated plants were treated with actinomycin D. These observations, together with some additional information on rates of TAV accumulation in plant tissue under various conditions, support a concept of competition between the virus and its host for substrates and access to ribosomes. As ribosomal concentration falls markedly in plants undergoing heat treatment concomitant with an increase in host protein synthesis, an hypothesis is advanced that viral RNA competes poorly with host messenger RNA for the limited numbers of available ribosomes on which to synthesise their respective proteins. This concept may also be used to account for the successes in obtaining virus-free material from infected plants by meristem culture. The rate of virus inactivation in whole plants at 36°c is much slower than the rate in expressed sap, and faster than the rate in purified virus preparations. Also, the kinetics of inactivation both 'in vivo' and in expressed sap do not fit a reaction of the first order, but one of a higher order, showing that inactivation at high temperature is not solely a direct thermal effect. Large increases in the levels of two enzymes, polyphenoloxidase and ribonuclease, occur during heat treatment and these may directly inactivate TAV. The extent of increase of these heat-induced enzymes may vary greatly with the species and variety of tobacco, thus providing an explanation for many past observations and suggestions implicating a role of the host in heat treatment therapy. Several observations indicates that the cytokinin concentration falls in heated plants. This results in an almost complete cessation of mitosis as well as a decrease in the ionic strength of the cell sap concomitant with a large increase in cell volume. The pH of the cell sap also falls markedly during heat treatment. probably reduce the stability of TAV. These changes The observations on alterations in cell size and mitotic activity are…

▼ The effects of tomato plant age, leaf age and imidacloprid on thrips probing and host settling behaviors were investigated for two thrips species, the tobacco thrips, Frankliniella fusca (Hinds) and the western flower thrips, F. occidentalis (Pergande) (Thripidae: Thysanoptera). A preliminary sampling experiment indicated that Frankliniella fusca was the more abundant thrips on pre-flowering tomatoes plants. Both thrips species were present and are important vectors of Tomato spotted wilt virus (TSWV). Plant age and imidacloprid effects were evaluated because previous field studies showed TSWV infection in tomato fields was affected by different plant ages and with imidacloprid treatment. Since thrips mortality has not been associated with these effects, plant age and imidacloprid might affect thrips probing and host selection behavior which ultimately could affect the thrips TSWV transmission efficiency. I used DC electrical penetration graph technique (EPG) to quantify thrips probing behavior. Whole plant bioassays were used in all settling experiments because F. occidentalis preferred leaves of whole plants to excised leaves or leaf discs. Males and female F. fusca probed and ingested more and longer on 3 and 4-week-old plants compared to 6 and 8-week-old plants. Female F. fusca probed and ingested more frequently than males in the plant age experiment but not in the leaf age experiment. Frankliniella fusca probed and ingested more frequently on 2 and 4-week-old leaves compared to 1-week-old leaves. Plant age did not affect the probing frequency or duration of F. occidentalis. Both thrips species preferred to settle on 3-week-old plants. Frankliniella fusca preferred to settle on old, 4-week-old leaves. Frankliniella occidentalis showed no settling preference for leaf ages. As imidacloprid concentrations in leaf tissues increased, F. fusca probing frequency and duration declined while F. occidentalis probing frequency and duration increased. In addition, ingestion frequency and duration declined for F. fusca and increased for F. occidentalis as imidacloprid concentrations increased in the plant tissue. Frankliniella fusca avoids leaves with imidacloprid and settles on untreated leaves, while F. occidentalis settles randomly when offered the choice to settle on imidacloprid and untreated leaves.

▼ Cysteine protease inhibitors (cystatins) are expressed in plants in response to wounding and insect herbivory and they form part of the native host-plant defence system. Cysteine proteases are enzymes important in the break down of dietary proteins mainly in the mid gut of coleopteran insects such as the banana weevil. The inhibition of these proteases has a direct effect on the digestive activity of the insect resulting in protein deficiency. This significantly affects insect development and survival. Based on these observations, strategies have been designed involving expression of cysteine protease inhibitors for the transgenic control of insect pests of several crop plants. For this study, it was hypothesized that the major proteases in banana weevil are cysteine proteases and can be effectively targeted by plant cystatins. It was further hypothesised that since plant cystatins are defense related, certain amino acid residues may have undergone positive selection. This provides an opportunity to increase their inhibitory potential to the weevil gut proteases via protein engineering. To prove the hypotheses, both in-vitro and in-vivo assays were set up thus allowing us to demonstrate the presence of cysteine type proteases banana weevil as well as the effect of cystatins on the weevil proteases and early development. Initial in-vitro experiments were able to characterize the proteolytic activity of the banana weevil gut proteases, which are mostly of the cysteine type, and in particular cathepsin B and L like. Two recombinant phytocystatins were further successfully produced using a 6xHis-tagged affinity chromatogephy system in Escherichia coli bacteria. The recombinant phytocystatins were used in a newly developed vacuum infiltration assay system using banana stems. Young weevil larvae were allowed to develop on phytocystatin-treated stems for up to 10 days. They had a 60% reduction in body weight and rate of growth compared to those that grew in untreated stems. By carrying out sitedirected mutagenesis to improve the inhibition efficiency of a model papaya cystatin, more than 8 amino acid residues were found to be subjected to positive selection. Mutation of amino acids yielded improved the inhibition potential of papaya cystatin against the model cysteine protease papain. Increased inhibition was greatest when amino acids were changed in the highly variable regions of the amino acid sequence very closely to the conserved regions. This study has been able to show for the first time that banana weevils use cysteine protease as major protein hydrolysis enzymes and that these can be effectively targeted by plant cystatins. It has also created novel phytocystatins using engineering of single amino acid sites following an evolutionary approach to modulate them for improved activity and targeting specific proteases.

Raphanus sativus, a common cruciferous vegetable has been attributed to possess a number of pharmacological and therapeutic properties. Water, methanol, acetone, ethyl acetate, chloroform and hexane extracts derived from root, stem and leaves of R. sativus were evaluated for the presence of phytochemicals such as isothiocyanates (ITCs) and polyphenolics. These extracts were checked for antioxidant and radical scavenging activity, antimicrobial activity, protective effect against oxidative damage induced by oxidants and anti-proliferative activity towards human cancer cell lines such as HeLa, A549, MCF-7 and PC-3 cells. Isothiocyanates (ITCs) were detected in considerable amount in root, stem and leaves of R. sativus. However, root extracts contained highest levels of ITCs, as compared to leaves and stem extracts. Highest amount of ITCs was extracted from root, when hexane was used as an extraction solvent. However, polar solvents were effective in recovering considerable amount of polyphenolics from R. sativus. R. sativus had total polyphenolic content, which was comparable to traditional rich source such as green and black tea. HPLC analysis indicated the presence of catechin, protocatechuic acid,syringic acid, vanillic acid, ferulic acid, sinapic acid, o-coumaric acid, myricetin and quercetin in R. sativus. Among different parts of R. sativus, leaves contained highest amount of phenolics and showed strongest antioxidant and radical scavenging activity. Of the different extraction solvents used, methanolic extract showed effective reductive capacity and significantly inhibited linoleic acid peroxidation, displayed metal chelating activity and effectively scavenged free radicals such as DPPH radicals, superoxide radicals, hydrogen peroxide and nitric oxide radicals respectively. All extracts except water extract of root, stem and leaves had a significant broad spectrum inhibitory activity. Ethyl acetate extract of root had potent antibacterial activity with significant inhibition, comparable to that of standard antibiotics against pathogenic bacteria. This was followed by ethyl acetate extract of leaves and stem. Further, ethyl acetate extract of different parts of R. sativus retained their antibacterial activity after heat treatment at 100°C for 30 min and their antibacterial activity was enhanced when pH was maintained in the acidic range, demonstrating their thermal stability and acid tolerance properties. Compositional analysis of ethyl acetate extract of root by GC-MS revealed the presence of polyunsaturated fatty acids (PUFAs), ITCs such as 4-(methylthio)-3-butenyl isothiocyanate (MTBITC) and 4-(methylthio)-3-butyl isothiocyanate (erucin), alkanes, eugenol and methyl cholesterol. Significant antibacterial activity of ethyl acetate extract of R. sativus root could be attributed to complex mixture of phytochemicals present in it R. sativus extracts per se showed no cytotoxicity and genotoxicity to lymphocytes.

▼ Three (3) medicinal plants [Aframomum melegueta K. Schum., Xylopia aethiopica (Dunal.) A. Rich. and Capsicum annuum L.] were selected based on their traditional uses in the treatment of diabetes in Africa. Various crude extracts and fractions from different parts of the plants were screened using several anti-oxidative and anti-diabetic tests in vitro. Most active fractions from each plant were used to examine in vivo anti-diabetic activity in type 2 diabetes (T2D) rat model. Additionally, possible bioactive compounds from most active extracts and fractions were analyzed by using GC-MS, TLC and NMR spectroscopy. The results showed that ethanolic extracts derived from the fruits of the plants demonstrated excellent anti-oxidative and anti-diabetic activities in vitro compared to other extracts from the same or different parts of these plants. After fractionation, ethyl acetate fraction from A. melegueta and acetone fractions from X. aethiopica and C. annuum exhibited strong radical scavenging (IC₅₀: 1-120 μg/mL) activity, inhibition of hemoglobin glycation (IC₅₀: 100-150 μg/mL), α-amylase (IC₅₀: 50-170 μg/mL) and α-glucosidase (IC₅₀: 40-87 μg/mL) activities hence were used for the in vivo study. The GC-MS analysis of the three (3) most active fractions revealed the presence of mostly phenolic compounds of 4-hydroxy-3-methoxyphenyl derivatives. Furthermore, the data of the in vivo study showed that oral intervention of the fractions (150 and 300 mg/kg bw) for 4 weeks demonstrated potent anti-diabetic actions via improving body weight gain, reducing feed and fluid intake and hyperglycemia, improving glucose tolerance ability, insulin sensitivity, amelioration of pancreatic β-cell histology and β-cell functions, improving dyslipidemia in a T2D rat model. Additionally, the pancreatic histopathological damages and other oxidative damages caused by the induction of diabetes were attenuated to near normal in the liver, kidney, heart and pancreas of the treated animals. The bioassay-guided fractionations lead to the isolation of 3 arylalkanes (6-paradol (1), 6-shagaol (2), and 6- gingerol (3)) and oleanolic acid (4) from A. melegueta fruits, when oleanolic acid (4) was the first to be isolated from A. melegueta. Moreover, 6-gingerol (3) and oleanolic acid (4) were similarly isolated for the first time from X. aethiopica fruits as well. These compounds have exhibited significant inhibitions against the α-amylase and α-glucosidase actions and thus are possible anti-diabetic agents and the anti-diabetic action of A. melegueta and X. aethiopica fruits is attributed to the presence of these compounds. This study also confirmed the use of these plants in African anti-diabetic traditional medicines by traditional healers. However, further clinical study is required to confirm these effects in human subjects. Advisors/Committee Members: Islam, Shahidul M. (advisor).

▼ Cysteine protease inhibitors (cystatins) are expressed in plants in response to wounding and insect herbivory and they form part of the native host-plant defence system. Cysteine proteases are enzymes important in the break down of dietary proteins mainly in the mid gut of coleopteran insects such as the banana weevil. The inhibition of these proteases has a direct effect on the digestive activity of the insect resulting in protein deficiency. This significantly affects insect development and survival. Based on these observations, strategies have been designed involving expression of cysteine protease inhibitors for the transgenic control of insect pests of several crop plants. For this study, it was hypothesized that the major proteases in banana weevil are cysteine proteases and can be effectively targeted by plant cystatins. It was further hypothesised that since plant cystatins are defense related, certain amino acid residues may have undergone positive selection. This provides an opportunity to increase their inhibitory potential to the weevil gut proteases via protein engineering. To prove the hypotheses, both in-vitro and in-vivo assays were set up thus allowing us to demonstrate the presence of cysteine type proteases banana weevil as well as the effect of cystatins on the weevil proteases and early development. Initial in-vitro experiments were able to characterize the proteolytic activity of the banana weevil gut proteases, which are mostly of the cysteine type, and in particular cathepsin B and L like. Two recombinant phytocystatins were further successfully produced using a 6xHis-tagged affinity chromatogephy system in Escherichia coli bacteria. The recombinant phytocystatins were used in a newly developed vacuum infiltration assay system using banana stems. Young weevil larvae were allowed to develop on phytocystatin-treated stems for up to 10 days. They had a 60% reduction in body weight and rate of growth compared to those that grew in untreated stems. By carrying out sitedirected mutagenesis to improve the inhibition efficiency of a model papaya cystatin, more than 8 amino acid residues were found to be subjected to positive selection. Mutation of amino acids yielded improved the inhibition potential of papaya cystatin against the model cysteine protease papain. Increased inhibition was greatest when amino acids were changed in the highly variable regions of the amino acid sequence very closely to the conserved regions. This study has been able to show for the first time that banana weevils use cysteine protease as major protein hydrolysis enzymes and that these can be effectively targeted by plant cystatins. It has also created novel phytocystatins using engineering of single amino acid sites following an evolutionary approach to modulate them for improved activity and targeting specific proteases.

▼ The study's main objective was to carry out an appraisal of the communication modes and messages used by the Forest Department in curbing deforestation in National Forest Reserves. Kalulu Forest, in Kabwe, Central Province was chosen for the case study. Kalulu Forest was made a National Reserve due to the presence of the water catchment area which provides household water to the residence of Kabwe. The forest was put there to act as a carbon sink. The research was carried out at the Forest Department in Kabwe and eight of the cooperating partners involved in policy formulation and service provision in Kalulu Forest. The researcher also interviewed one hundred and twenty squatters and six headmen. The data was collected through the distribution of questionnaires and analysed using the Statistical Package for Social Sciences. In-depth interviews and Focus Group Discussions were also used. The results revealed a number of important things. No participatory communication strategies and campaigns are employed in trying to educate the squatters on the importance of conserving Kalulu. None of the squatters have ever participated in any conservation program such as an aforestation project. Most of the squatters moved into the forest after being retrenched, reaching retirement or after none renewal of job contracts. Farming is the most common form of survival. Most of the crops grown include maize, soya beans, ground nuts, sweet potatoes and vegetables. Sunflower and cotton are grown on a small scale. Food is grown for household food security whilst the surplus maize is sold to Food Reserve Agency who has set up a depot in the forest reserve known as Makupu Depot. Focus Group Discussions were identified as the main means of communication between the Forest Department and the squatters. However, most of the discussions held were based on informing the squatters the reasons as to why they need to leave the forest and not how they come on board as partners and assist in protecting the forest. The study recommends that the current legislation on forests, which explicitly forbids for the occupation of people in forest reserves, be nullified in order for the forest department to be able to fully embrace environmental sustainable programs such Joint Forest Management and Community Based Forest Management which will allow the squatters to partake as partners and participants in development projects that pave way for them to live in harmony with the environment. Education and environmental awareness should be brought to the squatters through the use of theatre, drama, and focus group discussions. Local knowledge should be incorporated and not ignored.

▼ The protein encoded by the Nonexpressor of pathogenesis-related gene 1 (NPR1) also referred to as Non inducible immunitiy 1 (NIM1) or Salicylic acid insensitive 1 (SAI1) is a co-transcriptional regulator. The NPR1 gene plays a pivotal role in conferring broad spectrum resistant to plants. Elicitors like salicylic acid and pathogens coupled with the accumulation of reactive oxygen species influence its activation in the cytoplasm. The downstream activity of the NPR1 gene necessitates its translocation to the nucleus and an interaction with other transcription factors with a ‘TGAC’ core sequence for the induction of Pathogenesis-related genes. In this study I identified and isolated homologues of genes encoding the NPR1 protein in banana (Musa sp.). Southern blot analysis revealed the possible existence of more than one Musa NPR1 gene in four different banana cultivars. Furthermore, two banana NPR1 gene fragments designated (MNPR1A and MNPR1B) were isolated and their full lengths recovered and deposited in the gene bank. A preliminary phylogenetic analysis of Musa NPR1 revealed that the two newly isolated banana genes grouped closely with other monocot NPR1 genes. The two identified MNPR1-sequences differed greatly in their expression profile using quantitative real time polymerase chain reaction following either salicylic acid or methyl jasmonate treatment or treatment with Fusarium oxysporum Schlecht f. sp. cubense (Smith) Snyd. MNPR1A was expressed after Fusarium treatment with higher and earlier expression in the Fusarium-tolerant banana cultivar GCTCV-218 than in the Fusarium-susceptible banana cultivar Grand Naine. In comparison, MNPR1B was highly responsive to salicylic acid, but not to methyl jasmonate treatment, in both the tolerant banana cultivar GCTCV-218 and the susceptible banana cultivar Grand Naine. Expression of the MNPR1 genes correlated to Pathogenesis-related gene expression known to be involved in fungal resistance. It was found as a new result in this study that reduced sensitivity to Fusarium in GCTCV-218 might be partially attributed to the higher and an earlier expression of both MNPR1A and Pathogenesis-related-1 genes in this cultivar after Fusarium treatment.

In this study I identified and isolated homologues of genes encoding the NPR1 protein in banana (Musa sp.). Southern blot analysis revealed the possible existence of more than one Musa NPR1 gene in four different banana cultivars. Furthermore, two banana NPR1 gene fragments designated (MNPR1A and MNPR1B) were isolated and their full lengths recovered and deposited in the gene bank. A preliminary phylogenetic analysis of Musa NPR1 revealed that the two newly isolated banana genes grouped closely with other monocot NPR1 genes. The two identified MNPR1-sequences differed greatly in their expression profile using quantitative real time polymerase chain reaction following either salicylic acid or methyl jasmonate treatment or treatment with Fusarium oxysporum Schlecht f. sp. cubense (Smith) Snyd. MNPR1A was expressed after Fusarium treatment with higher and earlier expression in the Fusarium-tolerant banana cultivar GCTCV-218 than in the Fusarium-susceptible banana cultivar Grand Naine. In comparison, MNPR1B was highly responsive to salicylic acid, but not to methyl jasmonate treatment, in both the tolerant banana cultivar GCTCV-218 and the susceptible banana cultivar Grand Naine. Expression of the MNPR1 genes correlated to Pathogenesis-related gene expression known to be involved in fungal resistance. It was found as a new result in this study that reduced sensitivity to Fusarium in GCTCV-218 might be partially attributed to the higher and an earlier expression of both MNPR1A and Pathogenesis-related-1 genes in this cultivar after Fusarium treatment.

Medicinal plants are used in rural India to treat diabetes due to their traditional acceptability and availability. The plants are used as a crude extracts or as mixtures to treat diabetes. Plant extracts have their own importance and now being studied extensively due to having little or no side effects. Protein glycation takes place when elevated levels of reduced sugars react with amino groups in proteins, reaction known as Maillard reaction. If this process continues, it will lead to the formation of complex, often unstable, irreversible and reactive compounds “AGEs”, a process that may take weeks or even months to accomplish. The present study demonstrates that presence of AGEs-induced IgG damage in type 1, type 2 diabetes and hyperlipidemic patients. The study further purposes that in addition to IgG in serum concentration the quality of IgG molecule may not only be a crucial feature affecting its immunologic effects but also a risk factor as AGEs damage in diabetic and hyperlipidemic patients. The present study also provided evidence to suggest that the glycation of isolated IgG from diabetes and hyperlipidemic patients lead to alteration in the conformational as well as the biological properties of IgG. Further in present study Eulophia campestris and Eulophia nuda was selected and used to check the Maillard reaction inhibitory activity. Different combinations of glucose, protein and plant extracts (Eulophia campestris and Eulophia nuda) were made under in vitro conditions and their activity were monitored with trichloro acetic acid treatment method at 350 nm. Maillard reaction products/ AGEs were more with high glucose and high protein concentration and these were decreased by highest concentrationof Eulophia campestris and Eulophia nuda extract i.e. 30 mg/mL or 300 μL. Lower concentrations of plant extract produced either no or least response against Maillard reaction.

Natural herbal Plants are the major sources for various therapeutic agents in the treatment of a wide variety of diseases. The potency of herbal drugs against diseases is mainly due to the presence of different chemical constituents within them. Plants with flavonoids and related compounds (polyphenols) belong to the recently popular phytochemicals. Plants with these compounds possess various therapeutic properties, which includes antiviral, antiallergic, antiplatelet, antiestrogen, anticarcinogenic, antiproliferative, anti-oxidant and antianalgesic properties etc. newlineIn the present work, two different herbal plants Talinum cuneifolium Linn and Flemingia wightiana Graham ex Wt. and Arn belongs to the family Portulacaceae and Fabaceae of plant kingdom were under taken to test their potency as immunomodulators. Here Immunomodulation is determining their pharmacological and biological role in diseases treatment. Since there was no scientific evidence on the biological and pharmacological activities of Talinum cuneifolium extract, and there were no phytochemical studies on Talinum cuneifolium ethanol extract, we carried out the research on this extract. In addition, another plant Flemingia wightiana was selected for the research work. In this study, the potency of ethanolic extract of Talinum cuneifolium and Flemingia wightiana were tested against various disease parameters in experiments. The Preliminary phytochemical studies of EETC confirmed the presence of alkaloids, flavonoids, tannins, steroids, carbohydrates, proteins and in EEFW demonstrated the presence of alkaloids, triterpenoids, flavonoids, tannins, steroids, carbohydrates and proteins. The microbiological studies of these extract were given significant results that, EETC and EEFW were effective against gram positive bacteria than gram negative group. The pharmacological studies of EETC and EEFW crude extract were revealed that these plants are potential therapeutic agents against various disease parameters such as anti-inflammatory and analgesic activities.

Some metals at lower concentration are essential for cells but all metals are toxic at higher concentrations. Heavy metal pollution of soil and water caused by mining, burning of fossils fuels, smelting of metalliferous ores, and agriculture waste, is a major environment problem and exposure to these metals can be toxic to living cells. Use of plants for decontamination/minimization of heavy metal pollutants has attracted attention because of the problems associated with pollutant removal using conventional methods such as soil replacement, solidification, electro-kinetic extraction and washing strategies. Phytoremediation is a cost effective emerging technology based on the use of green plants to clean up the polluted sites and is accepted publicly. Research efforts made towards understanding the mechanism of metal tolerance has generated a great deal of information but it remains ill understood. Thus, there is scope for research to understand the mechanism of metal tolerance by various plant species and to identify the site and form of metal accumulation within plant system. This thesis entitled “Studies on Metal Tolerance in Plants” was designed to study the metal stress on different plant species including a herb (Peanut), a shrub (Jojoba) and a tree (Pongamia). Peanut (Arachis hypogaea L.) is a unique leguminous plant for its characteristic behavior to produce the pods underground in direct contact with soil. It has the double advantage for absorption of Cd from soil through roots and directly through the shells. Jojoba (Simmondsia chinensis) is an industrial crop – its seed wax is used in the cosmetic industry, as a lubricant, etc. The crop has considerable potential for cultivation in arid and semi-arid regions. In vitro nodal segments of jojoba respond to salinity in a similar way as the whole plant, so plant tissue culture technique could be used for preselection and evaluation of metal tolerance in this species.

▼ Rangelands are widespread and include grasslands, shrublands, and woodlands, covering more than two thirds of the earth’s land surface. This cover type represents half of the land area in the United States. These systems are extremely dynamic and respond to natural processes as well as varying degrees of human impact. In the southern Great Plains, land cover and land use have changed dramatically over the last century. However, there is tremendous uncertainty as to the timing and magnitude of such transitions and much more so regarding the effects on hydrology and sediment dynamics in these areas. Using a watershed approach in the Lampasas Cut Plain of Texas, we applied object-oriented classification methods and hand-digitizing of historical aerial photos to track the extent of woody plant cover, cropland area, and small ponds through time. We compared these results with population trends to determine the relationship between social and environmental variables. Finally, we conducted sediment analyses of cores from constructed reservoirs in each watershed to establish a chronological sequence of rangeland processes. Woody plant cover displayed very complex responses between areas yet was very similar among watersheds in the same setting. Prolonged decreases occurred over the first half of the study period before rebounding in Lampasas County. By contrast, shrub cover decreased and remained low and stable in Mills County over the last several decades. Woody cover in an urbanized watershed consistently increased. Cropland area showed marked decreases over all areas, declining by 77% between the 1930s and 2012. The number of small ponds increased by over 250% over the same period. Trends in woody plant cover were closely related to population in each context. The opposing trends of cropland and pond density were strongly correlated. Precipitation, streamflow, and baseflow were largely unchanged over the last 90 years, suggesting a minimal impact of land use and land cover on local hydrology. Sediment delivery did increase immediately after drought periods, when intense rainfall caused soil loss as a result of drought-induced vegetation loss. These findings are critical to understanding the implications for future sustainability of rangeland landscapes and the ecosystem services they provide.

▼ Bamboo is an ancient woody grass widely distributed in tropical, subtropical and mild temperate zones. There are about 1 200 species of bamboo in some 90 genera, of which two species namely highland and lowland bamboo are indigenous to Africa and widely distributed in Ethiopia. Ethiopia has more than 1 million hectares of bamboo which is 67% of African total. But compared to other bamboo growing countries Ethiopia is not getting equivalent economic advantage from the resource. Therefore, the aim of this paper is to show the benefit from the resource by developing the development and utilization model of bamboo and studying the establishment of processing plants for some selected products in Amhara regional state. These two Ethiopian bamboo species are found in Amhara region. But like any other regions the resource is not used as an input to processing plants that produce industrial and construction products. Some bamboo growing areas of the region are visited; data collected and the resource growing areas by zones and weredas are mapped. Domestic wood demand and supply is analyzed which shows huge gap between the demand and the available supply - demand by far exceeding suply. There is also increasing demand for bamboo and bamboo products in world market. General Model is developed to show the required integration between different parties to facilitate the development and utilization of the resource in Amhara region from cultivation to end market. In addition, cultivation, micro and small scale, and medium and large scale business models are developed with their corresponding components. Three products – bamboo flooring, bamboo mat and bamboo incense stick are selected for analysis for their technical and commercial viability. Required facilities are determined, project implementation plan is scheduled, and layout is developed for these three manufacturing lines. Finally detailed economic evaluation is made and shows - with the initial investment of Br. 41 million, the expected return will be Br. 94 million annually, with a payback period of less than a year. Projecting this result to national level, the country can get more than Br. 10 billion every year from the existing resource coverage. This figure could well be much higher if the cultivation and development efforts are made. The project is very attractive for investment and will help to improve the development and utilization of the resource. In addition the area of coverage and productivity of the resource should be improved, so that the country will entertain the maximum benefit out of this new sector.

▼ Pelargoniums have been studied extensively for their medicinal properties. P. reniforme and P. sidoides in particular are proven to possess antimicrobial, antifungal and antibiotic abilities due to their high antioxidant potential from compounds isolated from their tuberous roots. These plants have now been added to the medicine trade market and this is now causing concern for conservationists and they are generally harvested from the wild populations. This study evaluated the effect of water stress alone and in conjunction with arbuscular mycorrhiza on two species of Pelargoniums grown in a soilless medium. The experiment consisted of five different watering regimes which were applied to one hundred plants of each species without inoculation with arbuscular mycorrhiza and to one hundred plants of each species in conjunction with inoculation with AM. All the plants in the experiment were fed with a half-strength, standard Hoagland nutrient solution at varying rates viz. once daily to pot capacity, every three days to pot capacity, every six days to pot capacity, every twelve days to pot capacity and every twenty-four days to pot capacity. The objectives of the study were to measure the nutrient uptake, SPAD-502 levels (chlorophyll production) and metabolite (phenolics) formation of both species, grown under various rates of irrigation and water stress, as well with or without the addition of arbuscular mycorrhiza at planting out. Each treatment consisted of 10 replicates. SPAD-502 levels were measured weekly using a hand held SPAD-502 meter. Determination of nutrient uptake of macronutrients N, K, P, Ca, Mg and Na and micronutrients Cu, Zn, Mn, Al and B were measured from dry plant material at the end of the experiment by Bemlab, 16 Van Der Berg Crescent, Gants Centre, Strand. Plant growth in terms of wet and dry shoot and root weight were measured after harvest. Determination of concentrations of secondary metabolites (phenolic compounds) were assayed and measured spectrophotometrically at the end of the experiment. The highest significant reading of wet shoot weight for P. reniforme was taken in treatments 1 and 2 with and without mycorrhiza i.e. WF1, WF1M, WF2 and WF2M, with the highest mean found in WF1 with no mycorrhiza. This indicates that under high irrigation AM plays no part in plant growth, possibly due to leaching. More research is necessary in this regard. With regard to wet root weight, this was found to be not significant in any of the treatments, other than the longest roots being found in WF4. Measurements for dry root weight showed that WF1,2,3 and 5 were the most significant at P≤ 0.001 significance, with the highest weight found at treatment being WF3 and WF3M. The highest mean of shoot length of the plants was measured in treatment WF2 at moderate watering, but no statistical difference was found with water application and mycorrhiza addition. Nutrient uptake was increased in P. sidoides in all the different watering levels in the experiment except in the uptake of Mg. AM inoculation showed an… Advisors/Committee Members: Venter, A., Mrs (advisor).
