Species boundaries and hybridization in central-European Nymphaea species inferred from genome size and morphometric data

Popis výsledku v původním jazyce

Aquatic plants often pose considerable taxonomic problems. The genus Nymphaea (water lily) in central Europe is a good example of this in that their morphological similarity blurs the boundaries between species, which in addition are highly phenotypically plastic and possibly hybridize. The situation is further complicated by the occurrence of many garden cultivars. We used DNA flow cytometry and multivariate morphometrics (both distance-based and geometric) to obtain an insight into their phenotypic variation, identify taxon-specific characters and assess the frequency of hybridization in water lilies collected from 72 localities in the Czech Republic. For comparative purposes, we also included 34 garden cultivars. Flow cytometric measurements revealed a 45% difference in the holoploid genome sizes of N. alba and N. candida, which makes it easy to reliably separate them. In addition, the great majority of garden cultivars have distinctly smaller genomes than their native counterparts.
