Plant genomes vary in size and complexity, fueled in part by processes of whole-genome
duplication (WGD; polyploidy) and subsequent genome evolution. Despite repeated …

Arabidopsis is a model system not only for studying numerous aspects of plant biology, but
also for understanding mechanisms of the rapid evolutionary process associated with …

Genomic evidence of ancestral whole genome duplication (WGD) and polyploidy is
widespread among eukaryotic species, and especially among plants. WGD is thought to …

To study the evolutionary effects of polyploidy on plant gene functions, we analyzed
functional genomics data for a large number of duplicated gene pairs formed by ancient …

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

Although plant polyploidization is ubiquitous in nature, polyploidy has long been considered
an evolutionary dead end, precluding further species diversification. However, recent …

Deciphering the global distribution of polyploid plants is fundamental for understanding
plant evolution and ecology. Many factors have been hypothesized to affect the uneven …

Highlights•Genomic legacies of the ancestors may affect duplicate gene evolution in
allopolyploids.•Duplicate gene loss in allopolyploids is often distinctly non …

Polyploidy is defined as an increase in genome DNA content. Throughout the plant and
animal kingdoms specific cell types become polyploid as part of their differentiation …

The evolutionary fate of polyploids (especially plants) immediately following their formation
has recently received renewed attention by several research groups. An increasing body of …
