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

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

Polyploidy is important in the evolutionary history of plants, and it has played a crucial role in
shaping the genome structures of all eukaryotes. New and rapidly improving techniques in …

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

Publisher Summary This chapter provides a discussion of recent advancements, in context
to plant polyploidy. Polyploidy plays a very important role in plant evolution. Major recent …

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 …

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 …

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

Plant speciation and diversification strongly rely on structural changes in the nuclear
genome, both at the whole ploidy and individual chromosome level. Phylogenetic …

Polyploidy, the multiplication of chromosome sets above the diploid state, is arguably as
prevalent in plants as any other eukaryotic group. Over the past century, polyploidy has …
