Genome doubling, or polyploidy, is a major factor accounting for duplicate genes found in
most eukaryotic genomes. Polyploidy has considerable effects on duplicate gene …

Background Most, if not all, green plant (Virdiplantae) species including angiosperms and
ferns are polyploids themselves or have ancient polyploid or whole genome duplication …

Allopolyploidy is a prominent mode of speciation in higher plants. Due to the coexistence of
closely related genomes, a successful allopolyploid must have the ability to invoke and …

Polyploid organisms carry more than two copies of each chromosome, a condition rarely
tolerated in animals but which occurs relatively frequently in the plant kingdom. One of the …

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

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

Many of our major crop species are polyploids, containing more than one genome or set of
chromosomes. Polyploid crops present unique challenges, including difficulties in genome …

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

McGrath et al., 2014; Scienski et al., 2015) revealed that many eukaryotes do indeed have a
polyploid ancestry. Although there have been recent debates on the average fate of …

Enormous strides have been made in the study of polyploidy over the last 20 yr. Here, we
highlight some of these discoveries and note where our understanding of polyploid …
