Review: Homoeologous exchanges, segmental allopolyploidy, and polyploid genome evolution (Front. Genetics)

Polyploidy or whole-genome duplication (WGD) is an important process in plant evolution and speciation. Additional sets of chromosomes can be derived from intraspecific genome duplication (autopolyploidy) or hybridization of divergent genomes and chromosome doubling (allopolyploidy). In early stages…
