Název v původním jazyce
High genetic diversity in isolated populations of Thesium ebracteatum at the edge of its distribution range
Popis výsledku v původním jazyce
The aim of this study was to estimate the degree and distribution of genetic diversity within Central-European populations of Thesium ebracteatum-one of the most endangered plant species in Europe. By analyzing allozymes from 17 populations, we estimatedthe distribution of genetic diversity and suggest the most valuable populations for conservation. Analysis of molecular variance results showed the highest variance existed between populations (54 %), whereas the mean variance within populations was 46%. A surprisingly low degree of variance (less than 1 %) was found between the six studied regions. We also observed no correlation between geographical and genetic distance, which supports the idea that individual populations are strongly isolated. T. ebracteatum undergoes extensive clonal growth and may survive for very long periods of time without generative reproduction. Consistent with this, we found a strong and significant relationship between genetic diversity and population size
