Present status of genetic diversity of Potamogeton praelongus populations in the Czech Republic.

Popis výsledku v původním jazyce

Potamogeton praelongus Wulfen (Potamogetonaceae) is considered a critically endangered species in the Czech Republic, with the last natural population in a standing oxbow in the Orlice river floodplain at Malšova Lhota, near Hradec Králové in E Bohemia.In this study, the genetic variability of plants from natural and introduced Czech populations and a rescue culture was determined using AFLP analyses. The analyses revealed a very low genetic variability in existing Czech micropopulations suggesting a predominant clonal propagation within the natural populations. This may also be a result of ongoing repatriation of in vitro micropropagated plants. However, we observed differences in the genetic profiles and higher genetic variability in plant individuals raised from seed in rescue cultures produced by sexual reproduction. This process could also be utilized to increase the genetic variability within natural and newly established populations.
