Polyploidy, the condition of having more than two sets of chromosomes, is very common in
the plant kingdom. However, the role of polyploidy, or whole-genome duplication (WGD), in …

Polyploidy is a major creative force in plant evolution, from ferns to flowering plants.
Estimates suggest that B70% of flowering plants have undergone at least one whole …

The “genomic shock” hypothesis posits that unusual challenges to genome integrity such as
whole genome duplication may induce chaotic genome restructuring. Decades of research …

Polyploidy is an evolutionary process whereby two or more genomes are brought together
into the same nucleus, usually by hybridization followed by chromosome doubling. As a …

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 …

Elucidating the causes and consequences of polyploidy (whole-genome duplication; WGD)
is arguably central to understanding the evolution of most eukaryotic lineages. However …

At least two whole-genome duplications (WGD) have profoundly influenced the evolution of
most, if not all, grass (Poaceae) genomes, with the most recent of these predating the …

Polyploids are species in which three or more sets of chromosomes coexist. Polyploidy
frequently occurs in plants and plays a major role in their evolution. Based on their origin …

Whole genome duplication (polyploidy) represents a primary mechanism of sympatric
speciation, especially in plants where it is particularly prevalent. In this chapter, we focus on …
