Unveiling a gap-free genome in rapeseed for enhanced agricultural insight and breeding

Allopolyploid oilseed rape (Brassica napus) plays a critical role in global agriculture, serving not only as a major oil crop but also as a nutritious vegetable and ornamental plant. Despite its importance, the current reference genomes, including the latest ZS11_HZAU version, are hindered by unresolved sequences, collapsed duplications, and gaps, limiting comprehensive genomic analysis.
