The degree and direction of subgenome expression bias in Brassica napus vary between cultivars, tissues and developmental stages
SUMMARY Most extant plant lineages show evidence of past polyploidisation events in their genomes. Allopolyploids arise from hybridisation, resulting in polyploid genomes comprising subgenomes from different ancestors. Adaptation to their environment, pre‐ and post‐hybridisation and selection for specific traits has le...
