Other claims from this paper (8)
- Observation Chromosome numbers and genome size of C. pratensis s.str. vary almost continuously.
- Mechanism The chromosome number and genome size variation of C. pratensis s.str. is caused by co-occurring euploid and dysploid cytotypes along with aneuploids.
- Mechanism Inter-cytotype mating likely accompanies the chromosome and genome size variation of C. pratensis s.str.
- Observation The polyploid cytotypes of C. pratensis s.str. are of single and multiple, spatially and temporally recurrent origins.
- Observation The tetraploid Cardamine majovskyi evolved at least twice in different regions by autopolyploidy from diploid C. matthioli.
- Mechanism The extensive genome size and genetic variation of C. rivularis reflect differentiation from geographic isolation, triploids of different origins and hybridization with C. matthioli.
- Mechanism Geographically structured genetic lineages of C. pratensis are interpreted as descendants from different source populations in multiple glacial refugia.
- Mechanism An interplay of allopatric and ecological divergence, hybridization, multiple polyploid origins and Pleistocene genetic reshuffling drove the evolution of the species studied.
