| Description
| - Many cyanobacteria commonly identified as belonging to the genus Nostoc are well-known cyanobionts (symbionts) of a wide variety of plants and fungi. They form symbioses with bryophytes, pteridophytes, gymnosperms and angiosperms that are considerably different in the type of reciprocal interaction between the host and the cyanobiont. The phylogenetic and taxonomic relationships among cyanobionts isolated from different hosts and Nostoc strains isolated from free-living conditions are still not well understood. We compared phylogeny and morphology of symbiotic cyanobacteria originating from different host plants (genera Gunnera, Azolla, Cycas, Dioon, Encephalartos, Macrozamia and Anthoceros) with free-living Nostoc isolates originating from different habitats. After preliminary clustering with ARDRA (amplified rDNA restriction analysis), phylogeny was reconstructed on the basis of 16S rRNA gene sequences and compared with morphological characterization, obtaining several supported clusters. Two main N

- Fylogeneze a morfologická variabilita byla studována u vláknitých sinic řádu Nostocales pocházejících z různých hostitelských organizmů (Gunerra, čeleď Cycadaceae, Anthocerros, Azolla). Po předběžném rozřadění kmenů na základě ARDRA (amplified rDNA restriction analysis) byla fylogeneze rekonstruována pomocí kompletních sekvencí 16S rRNA. U studovaných kmenů byla provedena podrobná morfologická studie zahrnující hlavní morfomertické znaky. Symbiotické kmeny byly v rekonstruovaném zahrnuty pouze do dvou skupin. Přičemž první skupině byly volně rozplýleny mezi ostatními kmeny rodu Nostoc, zatímco v druhé skupině se nacházely pouze symbionti isolované z vodní kapradiny Azolla. Na základě našich výsledků se domníváme že v rámci vláknitých sinic řádu Nostocales existují dvě evoluční line ? první vede k málo specifickým symbiózám mezi sinicemi a hlevíky, cykasy, lišejníky atd., catímco druhá vedla k unikátní symbióze s kapradinou Azolla.
