Název v původním jazyce

Nuclear DNA content variation of Eleocharis palustris agg. in Europe

Popis výsledku v původním jazyce

Following morphological measurements and chromosomal counts, carried out on native populations in Austria, Bulgaria, Croatia, the Czech Republic, Denmark, Estonia, Germany, Hungary, Ireland, Italy, Lithuania, Luxembourg, the Netherlands, Norway, Portugal, Rumania, Slovakia, Slovenia, Spain, Sweden and Switzerland, which confirmed six taxa within the Eleocharis palustris agg. in Europe (Bureš 1998, 1999, 2002), we have focused on the study of relative DNA content variability of these taxa using DAPI flowcytometry. Both subspecies of E. mamillata, which have the same dominant chromosome number 2n=16, have very similar DNA contents. On the other hand, closely related E. palustris subsp. palustris in which 2n=16 also dominates, has a smaller DNA content than either subspecies of E. mamillata. It is also unusual that E. palustris subsp. vulgaris with a dominant 2n=38, 39 has a larger DNA content than E. uniglumis subsp. uniglumis, which has a dominant 2n=46. E. uniglumis subsp. sterneri, d
