1. Lazarević Jelena. Ectomycorrhiza of coniferous tree species in Montenegro with special attention to mycorrhiza of Pinus heldreihii Christ.

Degree: PhD, Forestry, 2013, University of Belgrade

Mycorrhizas are symbiotic associations formed between the group of specialized soil fungi and roots of higher plants. Mycorrhizas are present in all terrestrial ecosystems and play a central role in the nutrient uptake. In addition, mycorrhizal plants are often more resistant to diseases caused by microbial soil borne pathogens and to the effects of drought. Ectomycorhiza is being established with roots of trees, especially the families Betulaceae, Pinaceae, Fagaceae and Salicaceae, representing ecologically and economically most important tree species being dominated in boreal, Mediterranean forests and forests in temperate region. Analysis of diversity and distribution of ectomyccorhizas is important for understanding of their ecological function. According to published data, 50 ectomycorrhizal fungal genera have been recorded in Montenegro until now: 12 Genera of Ascomycota (50 taxa) and 38 Genera of Basidiomicota (267 taxa), representing c.ca one third of the total number of macromycetes’ records here. Pinus heldrechii Christ, being tertiar relict and subendemic, is one of the most interesting elements of Balkan’s dendroflorae. Fungal communities in P. heldreichii forests are only slightly examined, while their ectomycorrhizal communities have not been described or even confirmed. Due to evident ecological adaptibility, P. heldreichii could be used for afforestation of extreme terrains. In that sense, ectomycorrhizal fungi surviving on these soils should receive a special scientific attention. The overall aim of this doctorial dissertation was to introduce the ectomycorrhizal communities of Pinus heldreichii, also as to examine the possibilities of application of ectomycorrhizal fungi in nurrsery production of conifers. The collection of c.ca 40 of fungal culture’s isolates of putative ectomycorrhizal fungi from Montenegro area was established and used in further researches. Using different methods of inoculation under laboratory conditions, ectomycorrhiza were achieved between P. heldreichii and 18 fungal species. Genetic characterisation of fungal cultures was performed using molecular methods (ITS sequencing), and 22 fungal ITS sequences (20 ectomycorrhizal) were deposed in NCBI GenBank. This way, fungi from 10 ectomycorrhizal genera were characterised: Amanita, Boletus, Hebeloma, Lactarius, Russula, Suillus,Tricholoma, Pisolithus, Scleroderma, also as Chalciporus and Hypholoma. Using RFLP analysis with Hinf I, Alu I, Mbo I, Bsur, EcoRI i Rsa I restrictive enzymes, RFLP patterns for 25 taxa were obtained, which could serve as an efficient tool for their further monitoring. Characterization of ectomycorrhizal fungal communities of P. heldreichii, done by molecular analysis of plant roots on 2 localities with different soil development, shows their differences in composition and structure. In pioneer forest community of P. heldreichii on calcareous soils in initial phase, 11 morphotypes were identified on root samples, from which 29 ectomycorrhizal taxa were extracted. Species from genera Suillus, Rhizopogon,…
