Abstract: With the rapid development of sequencing technology and bioinformatics, the main crops of Brassica and its related species have been completed genome sequencing, whole genome resequencing and transcriptome sequencing. In order to facilitate the use of various omics data, different research teams have established a series of different Brassica omics databases from different perspectives, such as BRAD database, Brassica.INFO database,BnPIR database and BnaGVD database. In an effort to further promote Brassica crop genomics, transcriptomics and genetics researchers to use these databases, we reviewed the current main Brassica biological database and Brassica napus database, summarizes some problems existing in Brassica biological database, and makes prospects for the development of databases in the future.
