Highlights•Post-polyploid diploidization (PPD) in angiosperms usually operates by
descending dysploidy.•PPD is acting with differing intensities and rates.•Multiple base …

Advances in recent years have revolutionized our understanding of both the context and
occurrence of polyploidy in plants. Molecular phylogenetics has vastly improved our …

Most land plants are now known to be ancient polyploids that have rediploidized.
Diploidization involves many changes in genome organization that ultimately restore …

Highlights•Polyploidy or whole-genome duplication (WGD) is a ubiquitous feature of plant
genomes.•Polyploidy is most frequent in angiosperms.•A complex pattern of polyploidy is …

Polyploidy (whole-genome duplication; WGD) is common in plants and has long been
considered as both an important speciation mechanism and a crucial component of plant …

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

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

Investigators have long searched for a polyploidy paradigm—rules or principles that might
be common following polyploidization (whole‐genome duplication, WGD). Here we attempt …

Background Polyploidy or whole-genome duplication is now recognized as being present in
almost all lineages of higher plants, with multiple rounds of polyploidy occurring in most …

Polyploidy is a pervasive and recurring phenomenon across the tree of life, which occurred
at variable time scales, ecological amplitudes and cell types, and is especially prominent in …
