Subgenome dominance is an important phenomenon observed in allopolyploids after whole
genome duplication, in which one subgenome retains more genes as well as contributes …

Key message We report first-time synthesis of a stable Brassica allohexaploid. It may evolve
into a new species and also advance our understanding of pairing regulation and genome …

The genus Brassica contains a wide range of diploid and amphipolyploid species including
some of the most important vegetable, condiment and oilseed crops worldwide. As members …

Polyploidization is a widespread process that results in the merger of two or more genomes
in a common nucleus. To investigate modifications of gene expression occurring during …

Gene flow from diploid to polyploid species could have significant effects on the morphology
and ecology of polyploids. The potential of such introgression for bringing about …

Genetic models for polyploid crop adaptation provide important information relevant for
future breeding prospects. A well-suited model is Brassica napus, a recent allopolyploid …

There is increasing evidence that epigenetic marks such as DNA methylation contribute to
phenotypic variation by regulating gene transcription, developmental plasticity, and …

Risk assessment studies of transgenic crops have recently brought evidence of a low
spontaneous hybridization frequency of Brassica napus with Raphanus raphanistrum. The …

Recombination in ancient, heteromorphic sex chromosomes is typically suppressed at the
sex‐determining region (SDR) and proportionally elevated in the pseudoautosomal region …

Background Allopolyploidy is widespread in angiosperms, and they can coordinate two or
more different genomes through genetic and epigenetic modifications to exhibit stronger …
