Ensuring faithful homologous recombination in allopolyploids is essential to maintain
optimal fertility of the species. Variation in the ability to control aberrant pairing between …

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 …

Allopolyploids have globally higher fitness than their diploid progenitors; however, by
comparison, most resynthesized allopolyploids have poor fertility and highly unstable …

How do chromosomal regions with differing degrees of homology and homeology interact at
meiosis? We provide a novel analytical method based on simple genetics principles which …

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

This study explores how allopolyploidization reshapes the biased expression and
asymmetric epigenetic modification of homoeologous gene pairs, and examines the …

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 …

Many flowering plant taxa contain allopolyploids that share one or more genomes in
common. In the Brassica genus, crop species Brassica juncea and Brassica carinata share …

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 …

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