August 29, 2011, Shenzhen, China The Institute of Vegetables and Flowers Chinese Academy of Agricultural Science, Oil Crops Research Institute of the Chinese Academy of Agricultural Sciences, and BGI, the world's largest genomics organization, announced today that they were among the research organizations comprising the Brassica rapa Genome Sequencing Project Consortium (BrGSPC) that completed the genome sequence and analysis of the mesopolyploid crop B. rapa, a Chinese cabbage. The findings are published online today in Nature Genetics. This study marks a significant milestone in Brassica crops genome research, providing a new important resource for studying the evolutionary history of polyploid genomes and opening a brand way for the genetic improvement of Brassica oil and vegetable crops.
Brassica crops are used for human nutrition and provide opportunities for the study of genome evolution. These crops include important vegetables (B. rapa, Brassica oleracea) as well as oilseed crops (Brassica napus, B. rapa, Brassica juncea and Brassica carinata), which contribute to approximately 10% of the world's vegetable crop produce and approximately 12% of the worldwide edible oil supplies. The species B. rapa is a major vegetable or oil crop in Asia and Europe. It also serves as an excellent model system to study polyploidy-related genome evolution because of its paleohexaploid ancestry and its close evolutionary relationships with Arabidopsis thaliana and other Brassica species with larger genomes.
Since the Brassica rapa Genome Sequencing Project (BrGSP) was initiated about three years ago, scientists from China, United Kingdom, USA, Korea, Canada, France and Australia have been working on the studies of B. rapa genome, aiming to assist botanists and breeders worldwide in improving production, quality, nutritional value and dis
