| Description | Brassica carinata (BcBcCcCc), an important agricultural crop cultivated for edible oil and biofuel markets, provides favorable genetic variation that can be valuable for the improvement of Brassica crops and serves as an industrial crop in its own right. Here, we report the first pangenome comprising 127,421 gene models, which combines the genomes of 86 individual B. carinata accessions representing global genetic diversity. Two high-quality reference genomes for B. carinata were constructed, rigorously validated by genetic linkage mapping and annotated using the internationally-agreed nomenclature, with a total length at ~ 1.07 Gb and contig N50 more than 24 Mb. Using this pan-genome platform, we identified 1,820 candidate genes associated with plant development, productivity and seed quality traits in B. carinata. Focusing on pod shatter resistance, we characterized the key genes and reveal their evolutionary divergence within Brassica. This comprehensive study provides a valuable resource for understanding the genetic architecture of B. carinata traits and will usher the genomic-assisted breeding of Brassica crops. | ||||||||||||
