Polyploidy, a change whereby the entire chromosome set is multiplied, arises through
mitotic or meiotic misdivisions and frequently involves unreduced gametes and interspecific …

All natural plant species are evolved from ancient polyploids. Polyloidization plays an
important role in plant genome evolution, species divergence and crop domestication. We …

Background Polyploidy (whole-genome duplication) is an important speciation mechanism,
particularly in plants. Gene loss, silencing, and the formation of novel gene complexes are …

Abstract Whole-genome duplication (WGD), or polyploidy, events are widespread and
significant in the evolutionary history of angiosperms. However, empirical evidence for …

Whole-genome duplication (polyploidisation) is a widespread mechanism of speciation in
plants. Over time, polyploid genomes tend towards a more diploid-like state, through …

Many species comprise multiple cytotypes that represent autopolyploids, or presumed
autopolyploids, of the basic diploid cytotype. However, rarely has an autopolyploid been …

Hybridization and polyploidy are now hypothesized to have regularly stimulated speciation
in angiosperms, but individual or combined involvement of these two processes seems to …

Polyploidy is a key mechanism of genome evolution and speciation, particularly in plants.
Many aspects of polyploidy have been elucidated with the tools that have become available …

Two main attempts have been suggested for the biological significance of endopolyploidy:(i)
provision of high DNA amounts to support high synthetic demands in certain cells and (ii) …

Polyploidization, a widespread phenomenon among plants, is considered a major
speciation mechanism. Polyploid plants have a high degree of immediate post-zygotic …
