A chromosome-level reference genome facilitates the discovery of clubroot-resistant gene <i>Crr5</i> in Chinese cabbage.

ABSTRACT: Brassica rapa includes a variety of important vegetable and oilseed crops, yet it is significantly challenged by clubroot disease. Notably, the majority of genotypes of B. rapa with published genomes exhibit high susceptibility to clubroot disease. The present study presents a high-quality chromosome-level sequence of the genome of the DH40 clubroot-resistant (CR) line, a doubled haploid line derived from the hybrid progeny of a European turnip (ECD01) and two lines of Chinese cabbage. The assembled genome spans 420.92 Mb, with a contig N50 size of 11.97 Mb. Comparative genomics studies revealed that the DH40 line is more closely related to the Chinese cabbage Chiifu than to the turnip ECD04. The DH40 genome provided direct reference and greatly facilitate the map-based cloni
