Surviving a Genome Collision: Genomic Signatures of Allopolyploidization in the Recent Crop Species Brassica napus

Homeologous chromosome exchanges drive postpolyploidization genetic diversification in Brassica napus. Homeologous exchanges cause rapid genome size reduction after allopolyploidization. Segmental deletions contain genes associated with adaptive processes and chromosome stability. Breakpoints of genomic rearrangements contain motifs associated with meiotic recombination. Genes involved in chromosome mismatch repair are subject to selection after polyploidization.
