Polyploidy promotes the restructuring of merged genomes within initial generations of
resynthesized Brassica napus, possibly caused by homoeologous recombination at meiosis …

Polyploids can be produced by the union of unreduced gametes or through somatic
doubling of F1 interspecific hybrids. The first route is suspected to produce allopolyploid …

Meiotic recombination is a major evolutionary process generating genetic diversity at each
generation in sexual organisms. However, this process is highly regulated, with the majority …

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

Synthetic allohexaploid Brassica hybrids (2n= AABBCC) do not exist naturally, but can be
synthesized by crosses between diploid and/or allotetraploid Brassica species. Using these …

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 …

The crop species within the genus Brassica have highly replicated genomes. Three base
'diploid'species, Brassica oleracea, B. nigra and B. rapa, are likely ancient polyploids, and …

Polyploidy has contributed to the evolution of eukaryotes, particularly flowering plants. The
genomic consequences of polyploidy have been extensively studied, but the mechanisms …

Chromosomal rearrangements can be triggered by recombination between distinct but
related regions. Brassica napus (AACC; 2 n= 38) is a recent allopolyploid species whose …

Allopolyploid species contain more than two sets of related chromosomes (homoeologs) that
must be sorted during meiosis to ensure fertility. As polyploid species usually have multiple …
