The Chinese academy of agricultural sciences' fuel oil crops genomics and disease resistance improvement innovation team successfully break the whole transcription of rapeseed genome information code, build the gene transcription of canola plants more than 100000 panorama, makes rape gene function research, for the first time, have been the standard reference database of gene transcription, the strong support of rapeseed functional genes related research.

The rapeseed genome contains about 1.2 billion bases and more than 100,000 genes. How to interpret the massive genome information has become an important task in functional gene research. According to the central law, genes are transcribed into mrnas that are then translated into proteins. Because gene transcription is often spliced in many different ways, a single gene can make many different mrnas. Previously, due to the limitations of technology and resources, rapeseed has been short of transcriptional mRNA database of all genes at the genome-wide level, leading to the lack of searchable and referable gene annotation information in the study of rapeseed gene function.

In order to break through this bottleneck, genomics and disease resistance improvement innovation team using the latest three generation of sequencing technology and accurate determination of the rapeseed transcriptome, and independently developed a classification method for polyploid rape complex genomes, successfully mapped the rapeseed genome transcription panorama, build the rape "standard" reference transcription of this database. The research results have updated people's knowledge and understanding of rape genes and genomes, and will provide data basis and theoretical guidance for the research of functional genes and genetic improvement and genome design and breeding of brassica napus.
