| Description
| - Důležitým centrem rozšíření rodu Festuca L. je Pyrenejský poloostrov. Pro hodnocení fylogeneze a variability jaderného genomu kostřav bylo použito počítání chromozómů, fluorescenční (FISH) a genomické (GISH) in situ hybridizace a průtokové cytometrie (FCM) ke stanovení obsahu jaderné DNA. U Festuca duriotagana var. barbata byl poprvé určen počet chromozómů a nová úroveň ploidie byla zjištěna u F. rothmaleri a F. summilusitana. U posledně jmenovaných druhů byly v některých populacích, kromě dekaploidů, nalezeny i dodekaploidy, což naznačuje existenci dosud neznámého taxonu. Variabilita v počtu chromozómů byla potvrzena pomocí průtokové cytometrie a byla nalezena korelace mezi typy substrátu, kde F. summilusitana rostla. U každé sekce bylo při snížení velikosti genomu pozorováno zvýšení polyploidie. Obecně lze říci, že použití technik in situ hybridizace neumožnilo upřesnit fylogenetické vztahy mezi studovanými druhy. Pomocí FISH byla pozorována variabilita v poloze rDNA lokusů. Výsledky získané pomo... (cs)
- Festuca L. has an important diversification centre in the Iberian Peninsula. We used chromosome counting, fluorescence (FISH) and genomic in situ hybridization (GISH), and DNA flow cytometry (FCM) to clarify the taxonomic position of several taxa, to search for phylogenetic relationships and to assess the extent and pattern of genome variation in fescues. The chromosome number of Festuca duriotagana var. barbata is determined for the first time and new ploidy level estimations are given for F. rothmaleri and F. summilusitana. In the latter species, besides the reported decaploid level, dodecaploidy was found in some populations, which points to the existence of an unrecognized taxon. Moreover, these differences were confirmed by FCM and a high positive correlation was found with the type of substrate where F. summilusitana was growing. For each section, a decrease of genome size with increase of polyploidy was observed. In general, in situ hybridization techniques failed to reveal phylogenetic rela...
