简介
Brassica oleracea is an important vegetable crop that has provided ancestor genomes of the two most important Brassica oil crops, Brassica napus and Brassica carinata. The current B. oleracea reference genome (JZS, also named 02–12) displays problems of large mis-assemblies, low sequence continuity, and low assembly integrity, thus limiting genomic analysis. We reported an updated assembly of the B. oleracea reference genome (JZS v2) obtained through single-molecule sequencing and chromosome conformation capture technologies. We assembled an additional 83.16 Mb of genomic sequences, and the updated genome features a contig N50 size of 2.37 Mb, representing an ~ 88-fold improvement. We detected a new round of long terminal repeat retrotransposon (LTR-RT) burst in the new assembly. Comparative analysis with the reported genome sequences of two other genomes of B. oleracea …
