Abstract Background Prospero (Hyacinthaceae) provides a unique system to assess the
impact of genome rearrangements on plant diversification and evolution. The genus exhibits …

Abstract Background and Aims Chromosomal evolution, including numerical and structural
changes, is a major force in plant diversification and speciation. This study addresses …

Prospero is a Mediterranean autumn-flowering genus of Hyacinthaceae commonly
classified in Scilla as S. autumnalis and S. obtusifolia. Extensive dysploid and polyploid …

Odd ploidy-level cytotypes in sexually reproducing species are considered a dead end due
to absent or reduced fertility. If sterility is only partial, however, their contribution to the …

Polyploidization is generally considered to be an important evolutionary driver affecting the
genetic diversity, that can alter the morphology, phenology, physiology or ecology of plants …

While polyploidization is recognized as a major evolutionary driver for ferns and
angiosperms, little is known about its impact in gymnosperms, where polyploidy is much less …

The subsection Asperae of genus Hydrangea L.(Hydrangeaceae) has been investigated for
three reasons: several ambiguous classifications concerning Hydrangea aspera have been …

Supernumerary B chromosomes (Bs) are genomic parasitic components, originating from
the A complement via chromosomal rearrangements, which follow their own evolutionary …

Karyotypic evolution is a prominent feature in the diversification of many plants and animals,
yet the role that chromosomal changes play in the process of diversification is still debated …

Eight taxa of the genus Bellevalia (Hyacinthaceae) occurring in Greece, all with basic
chromosome number x á= á4, were cytologically studied using classical and molecular …
