The role played by whole‐genome duplication (WGD) in evolution and adaptation is
particularly well illustrated in allopolyploids, where WGD is concomitant with interspecific …

Allopolyploidisation merges evolutionarily distinct parental genomes (subgenomes) into a
single nucleus. A frequent observation is that one subgenome is 'dominant'over the other …

Transposable elements (TEs) represent an important fraction of plant genomes and are
likely to play a pivotal role in fuelling genome reorganization and functional changes …

Structural variation is a major source of genetic diversity and an important substrate for
selection. In allopolyploids, homoeologous exchanges (ie between the constituent …

Subgenome dominance is an important phenomenon observed in allopolyploids after whole
genome duplication, in which one subgenome retains more genes as well as contributes …

Polyploidy, or whole genome duplication, is a major evolutionary process that has shaped
eukaryotic genomes, notably those of flowering plants. The mechanisms underlying the …

Background Allopolyploids require rapid genetic and epigenetic modifications to reconcile
two or more sets of divergent genomes. To better understand the fate of duplicate genes …

Polyploidization is important to the evolution of plants. Subgenome dominance is a distinct
phenomenon associated with most allopolyploids. A gene on the dominant subgenome …

Allopolyploid formation requires the adaptation of two nuclear genomes within a single
cytoplasm, which may involve programmed genetic and epigenetic changes during the …

Polyploidization has played a major role in crop plant evolution, leading to advantageous
traits that have been selected by humans. Here, we describe restructuring patterns in the …
