Title
Allopolyploidy, which results from the merger and duplication of two divergent genomes, has played a major role in the evolution and diversification of flowering plants. The genomic changes that occur in resynthesized or natural neopolyploids have be...
Chromosomal reshuffling occurs during meiosis in newly created polyploid species in Brassica, contributing to differentiation of parental genomes in the hybrid. In newly synthesized Brassica napus, studies have shown little effect of the very first m...
Le colza et le rutabaga appartiennent à la même espèce, Brassica napus (AACC, 2n=38). Cette espèce allotétraploïde est issue de croisements naturels entre le chou B. oleracea (CC, 2n = 18) et la navette B. rapa (AA, 2n = 20). Aucun colza sauvage n’a ...
