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

Gene retention, fractionation and subgenome differences in polyploid plants
All natural plant species are evolved from ancient polyploids. Polyloidization plays an
important role in plant genome evolution, species divergence and crop domestication. We …

On the road to diploidization? Homoeolog loss in independently formed populations of the allopolyploid Tragopogon miscellus (Asteraceae)
Background Polyploidy (whole-genome duplication) is an important speciation mechanism,
particularly in plants. Gene loss, silencing, and the formation of novel gene complexes are …

Gene loss and silencing in Tragopogon miscellus (Asteraceae): comparison of natural and synthetic allotetraploids
Whole-genome duplication (polyploidisation) is a widespread mechanism of speciation in
plants. Over time, polyploid genomes tend towards a more diploid-like state, through …

Autopolyploidy in angiosperms: have we grossly underestimated the number of species?
Many species comprise multiple cytotypes that represent autopolyploids, or presumed
autopolyploids, of the basic diploid cytotype. However, rarely has an autopolyploid been …

Hybrid speciation in angiosperms: parental divergence drives ploidy
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, the nucleotype, and novelty: the impact of genome doubling on the biology of the cell
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 …

Endopolyploidy in seed plants
M Barow - BioEssays, 2006 - Wiley Online Library
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) …

The impact of the triploid block on the origin and evolution of polyploid plants
Polyploidization, a widespread phenomenon among plants, is considered a major
speciation mechanism. Polyploid plants have a high degree of immediate post-zygotic …
