Brassica rapa cultivar:Chiifu-401-42 Genome sequencing and assembly. Brassica rapa cultivar:Chiifu-401-42

The B. rapa genome was re-assembled by generating high-quality paired-end reads, larger mate-paired reads and extra single-molecule reads. Based on the newly assembled B. rapa genome, genes were re-annotated and high-density genetic maps were constructed to anchor the scaffolds. A new version of B. rapa genome and new gene models and refined gene structures were generated. The updated B. rapa genome and gene models should serve as a better reference for comparative genomics and gene function studies in Brassicas.
