For the genome, based on the previously published BnPIR database, we added the data of Ningyou7 and Express617 genome assemblies [1-3]. Totally, we collected the published genomic datasets from 11 representative core germplasms and annotated the gene function, domains, GO terms, and metabolic pathways of genes. The genome alignment were performed, and the genomic modules of collinearity, gene indexes, and phylogenetic relationships of homologous genes were updated. Based on the phylogenetic tree of homologous genes constructed with Arabidopsis as the outgroup, users can browse and compare the gene structures and functional domains of homologous genes in the gene search module to understand whether the homologous genes have undergone functional differentiation at the sequence level. Gene cluster, Gene index, Gene family, Pathway and Transcription factor respectively provide the information query of gene cluster, gene index, gene family, pathway and transcription factor of 11 rapeseed genomes. Genome synteny provides Gbrowser_syn and Dotplot browser for users to browse the alignment results between genomes. Pan-browser provides the previously constructed rapeseed pan-genome browser.
