Subgenome dominance in an interspecific hybrid, synthetic allopolyploid, and a 140-year-old naturally established neo-allopolyploid monkeyflower
Recent studies have shown that one of the parental subgenomes in ancient polyploids is
generally more dominant, having retained more genes and being more highly expressed, a …

Patterns and consequences of subgenome differentiation provide insights into the nature of paleopolyploidy in plants
Polyploidy is an important feature of plant genomes, but the nature of many polyploidization
events remains to be elucidated. Here, we demonstrate that the evolutionary fates of the …

Altered chromatin compaction and histone methylation drive non-additive gene expression in an interspecific Arabidopsis hybrid
Background The merging of two diverged genomes can result in hybrid offspring that
phenotypically differ greatly from both parents. In plants, interspecific hybridization plays …

Replaying the evolutionary tape to investigate subgenome dominance in allopolyploid Brassica napus
Allopolyploidisation merges evolutionarily distinct parental genomes (subgenomes) into a
single nucleus. A frequent observation is that one subgenome is 'dominant'over the other …
