Polyploidy, or the duplication of entire genomes, has been observed in prokaryotic and
eukaryotic organisms, and in somatic and germ cells. The consequences of polyploidization …

Most diploid organisms have polyploid ancestors. The evolutionary process of
polyploidization is poorly understood but has frequently been conjectured to involve some …

An interesting and possibly unique pattern of genome evolution following polyploidy can be
observed among allopolyploids of the Triticum and Aegilops genera (wheat group). Most …

Polyploidy has played an extensive role in the evolution of flowering plants. Allopolyploids,
with subgenomes containing duplicated gene pairs called homeologs, can show rapid …

Polyploidization and subsequent sub‐and neofunctionalization of duplicated genes
represent a major mechanism of plant genome evolution. Capsella bursa‐pastoris, a …

Polyploidy occurs in some animals and all flowering plants, including important crops such
as wheat. The consequences of polyploidy in crops remain elusive, partly because their …

Polyploidization, the process leading to the increase in chromosome sets, is a major
evolutionary transition in plants. Whole‐genome duplication (WGD) within the same species …

Allopolyploidization is a frequent evolutionary transition in plants that combines whole-
genome duplication (WGD) and interspecific hybridization. The genome of an allopolyploid …

Background Bread wheat is a recent allohexaploid (genomic constitution AABBDD) that
emerged through a hybridization between tetraploid Triticum turgidum (AABB) and diploid …

Naturally allotetraploid cotton has been widely used as an ideal model to investigate gene
expression remodeling as a consequence of polyploidization. However, the global gene …
