Allopolyploid speciation is widespread in plants, yet the molecular requirements for
successful orchestration of coordinated gene expression for two divergent and reunited …

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

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

Highlights•Dosage balance is fluid and will change over time.•Duplicate genes are
preserved by interplay of multiple overlapping mechanisms.•Distinguishing duplicate gene …

Polyploidy is produced by multiplication of a single genome (autopolyploid) or combination
of two or more divergent genomes (allopolyploid). The available data obtained from the …

Abstract Background and Aims Polyploidy is arguably the single most important genetic
mechanism in plant speciation and diversification. It has been repeatedly suggested that …

Although polyploidy has been involved in speciation in both animals and plants, the general
perception is often that it is too rare to have been a significant factor in animal evolution and …

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 …

Background Throughout the past century, hybridization and polyploidization have variously
been viewed as drivers of biodiversity (eg Arnold, 1997) or evolutionary noise, unimportant …
