Rice functional genomics and breeding database (RFGB)-3K-rice SNP and InDel sub-database

Rice is an important food crop worldwide. Genomic research on global germplasm has theoretical and practical significances in the mining of favorable alleles and on genome-based molecular breeding, which are related to Chinese and global food security. Through the 3000 (3K) Rice Genome Project, we collected single nucleotide polymorphism (SNP) and insertion and deletion (InDel) genomic variation data for the 2859 rice genomes, and establish a comprehensive SNP and InDel sub-database for the Rice Functional Genomics-based Breeding (RFGB) Database. This sub-database is a global resource containing a polymorphism information retrieval function, a genome browser visualization system and a data export system for specific genomic regions, along with other tools. This study establishes an important platform for rice gene functional research and rice molecular breeding by genomic selection.
