Deciphering the fragrance code: High-quality sequencing and analysis of the 'XiangQingCai' (XQC) genome

'Vanilla' (XQC, brassica variety chinensis), a Brassica rapa subspecies chinensis, is a vital vegetable crop in the Brassicaceae family, renowned for its intense volatile fragrance. Despite the significant progress that has been made in understanding the genomes of Brassica species, including the discovery of a whole-genome triplication event, XQC's genome remains unexplored.
