Rare occurrence of reciprocal hybridization in a sympatric population of the Czech stenoendemic Dianthus arenarius subsp bohemicus and widespread D. carthusianorum

Popis výsledku v původním jazyce

Hybridization between rare and common plant congeners can pose a serious threat to the rare species through gene swamping, production of hybrid seed at the expense of conspecific seed and/or hybrid competition for abiotic or biotic resources. Assessing the frequency and dynamics of interspecific hybridization is therefore of paramount importance for conservation purposes. Here we investigate, using DNA flow cytometry, multivariate morphometrics and chloroplast DNA sequencing, the frequency and directionof interspecific hybridization between the critically endangered Czech endemic psammophyte Dianthus arenarius subsp. bohemicus and its sympatric congener D. carthusianorum (Caryophyllaceae) in a single population in central Bohemia. Flow cytometry allowed unambiguous identification of both parental species, based on differences in the amounts of nuclear DNA and revealed a few individuals (< 1.1% of the samples analysed) with intermediate genome sizes that corresponded to F1 hybrids.
