Brassica allotriploids, a solution to deal with hampered meiotic recombination

Archive ouverte | Pelé, Alexandre | CCSD

International audience. Meiotic recombination by crossovers is the main mechanism used by breeders to shuffle the genetic diversity. Nevertheless, loci separation is often hampered due to the strict regul...

Brassica Allotriploids Hybrids: New Way to Exceed Recombination Limits for COs Rate and Distribution

Archive ouverte | Pelé, Alexandre | CCSD

International audience. Meiotic homologous recombination by crossovers (COs) is the main mechanism responsible for mixing genetic diversity in plant breeding. However, loci separations are limited due to the strict ...

The impact of open pollination on the structural evolutionary dynamics, meiotic behavior, and fertility of resynthesized allotetraploid Brassica napus L.

Archive ouverte | Rousseau-Gueutin, Mathieu | CCSD

International audience. 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 t...
