   About RISe

Rice is a major food staple for the world's population and serves as a model species in cereal genome research. The Beijing Genomics Institute (BGI) has long been devoting itself to sequencing, information analysis, and biological research of the rice genome. Our Rice Information System (BGI-RIS) is targeted to be the most up-to-date integrated information resource for rice genomes as well as a workbench for comparative genomic analysis among cereal crops.

In addition to the comprehensive data of Oryza sativa L. ssp. indica sequenced by BGI, BGI-RIS will host carefully curated genome information of Oryza sativa L. ssp. japonica (Syngenta) since we have obtained permission from Syngenta to release their data as soon as related paper is published.

In BGI-RIS, sequence contigs of Beijing indica and Syngenta japonica have been further assembled and anchored onto the rice chromosomes. We have annotated the rice genomes for gene content, repetitive elements, and SNPs. Sequence polymorphisms between different rice subspecies have also been identified. Designed as a basic platform for rice study, BGI-RIS presents the sequenced genomes and related information in systematic and graphical ways for the convenience of in-depth comparative studies.

   CompView

CompView is an interactive visualization tool that is being developed for identifying and visualizing conserved syntenic blocks (homoeologous chromosome segments and homologs) across multiple related genomes simultaneously.

Users can switch between CompView and MapView and start with a gene or region of interest in searching for related information. Once fully implemented, CompView will provide users with timely genomic information across species beyond genera and families.
