A unique diploid – triploid contact zone provides insights into the evolutionary mechanisms of cytotype coexistence in flowering rush (Butomus umbellatus)

Popis výsledku v původním jazyce

Despite the common incidence of polyploidy in many plant groups, particular ecological and evolutionary mechanisms facilitating intraspecific cytotype coexistence have been identified for just a handful of species and cannot yet be generalised. Here, we revealed and documented a unique complex of mixed diploid-triploid populations of the marshland perennial Butomus umbellatus in the Eastern Slovak Lowland. Altogether 42% of the sampled populations were mixed-ploidy, pointing to unexpectedly high rates of diploid-triploid coexistence. No ecological niche differences between the cytotypes were detected. Both cytotypes exhibited high and comparable investments into clonal traits, and reproductive assurance provided by asexual reproduction likely plays a key role in cytotype coexistence and triploid predominance. The common cytotype coexistence in this region seems to be also facilitated by periodical seasonal floods promoting transport of vegetative propagules among populations and providing long-term continuity of favourable sites by recurrent disturbances.
