Background The sharp increase of plant genome and transcriptome data provide valuable
resources to investigate evolutionary consequences of gene duplication in a range of taxa …

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 …

Combining the genomes of two species through hybridization and chromosome doubling
can create a new allopolyploid species virtually overnight. Although common in Nature, such …

Polyploidy is a common event in plants that involves the acquisition of more than two
complete sets of chromosomes. Allopolyploidy originates from interspecies hybrids while …

Hybridization and polyploidization are now recognized as major phenomena in the
evolution of plants, promoting genetic diversity, adaptive radiation and speciation. Modern …

▪ Abstract Here we review the biology of early generation neopolyploids and discuss the
profound changes that accompany their formation. Newly formed auto-and allopolyploids …

It has long been recognized that hybridization and polyploidy are prominent processes in
plant evolution. Although classically recognized as significant in speciation and adaptation …

All else being equal, polyploids are expected to have larger C-values (amount of DNA in the
unreplicated gametic nucleus) than their diploid progenitors, increasing in direct proportion …

We consider the rapidly advancing discipline of plant evolutionary genomics, with a focus on
the evolution of polyploid genomes. In many lineages, polyploidy is followed by 'biased …

Whole-genome duplication (WGD), which leads to polyploidy, is implicated in adaptation
and speciation. But what are the immediate effects of WGD and how do newly polyploid …
