| Description
| - In a previous study of microfungi associated with bark beetle S. intricatus and the decline of oaks, Geosmithia species appeared among the most frequent fungi. Geosmithia is a polyphyletic taxon with two species belonging to Hypocreales and eight to Eurotiales. The main aim of our project is to find a relationship among the cambial occurrence of geosmithias, presence of insects and the decline of oaks and contribute thus to knowledge on ecology. We have isolated over 70 strains from Scolytus/Quercusassociation and the sampling will continue in areas with prevailing oak woods, from different oak species, trees with various degrees of disease and other insects feeding on the wood/bark interface. Morphological study and analysis of rDNA sequences confirmed that our isolates differ from species described so far and belong to Hypocreales. Phylogenetic analysis of Geosmithia species will be performed using rDNA sequences. Ex type strains from established collections and database sequences will be (en)
- Fylogenetická analýza rDNA sekvencí rodu Geosmíthia prokázala, že osm druhu náleží mezi Eurotiales a dva druhy do řádu Hypocreales. Geosmithie jsou považovány za vzácné, avšak v našich předchozích studiích (GAČR 203/97/0037) jsme je často nalézali v kambiu odumírajících dubů napadených kůrovcem Scolytus intricatus, v jeho chodbičkách, na těle hmyzu i larev. Byly nalezeny čtyři morfologicky rozlišené skupin geosmithii z nichž pouze jedna přibližně odpovídala druhu G. putterilln. Cílem projektu je objasnit vztah mezi kambiálním výskytem geosmithii, přítomností hmyzu a odumíráním dubu a tak přispět ke znalostem o ekologii tohoto systému. Izolovali jsme více než 70 kmenů z asociace Scolytus/Quercus a sběry budou pokračovat v oblastech s převládajícími dubovými lesy, na různých druzích dubu a jiných opadavých dřevin, na dřevinách s různým stupněm napadení a dalších druzích hmyzu. Morfologická studie a analýza rDNa sekvencí ukázala, že naše isoláty náleží do řádu Hypocreales. Provedeme
