An analysis of over 10 000 plant genome sizes (GSs) indicates that most species have
smaller genomes than expected given the incidence of polyploidy in their ancestries …

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 …

Genome doubling (polyploidy) has been and continues to be a pervasive force in plant
evolution. Modern plant genomes harbor evidence of multiple rounds of past …

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

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 …

The reason why the DNA content, chromosome number and shape, and gene content of
eukaryotic genomes vary independently remains a matter of speculation. The same is true …

Unlike in mammals, plants rapidly delete functionless, nonrepetitive DNA from their
genomes. Following paleopolyploidies, duplicate genes are deleted by intrachromosomal …

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 …

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

The predictability of evolution is debatable, with recent evidence suggesting that outcomes
may be constrained by gene interaction networks [1]. Whole-genome duplication (WGD; …
