Abstract:

Chinese National Rice Data Center (http://www.ricedata.cn, CRDC) is an integrated scientific platform for rice research across multiple subjects. Firstly, the database for Chinese rice varieties and their genealogy (DRVG) is established including a fingerprint dataset for widely-grown varieties and a dataset for the excellent germplasm. Moreover, the genealogy tree and the assessment method of backbone parents are developed for DRVG. Secondly, the database for rice functional genes (DRFG) is built, which introduces rice functional genes collected from the references at home and abroad and have two chart generation programs for genetic maps and gene structures through browsers. In addition, the DRFG sets up a dataset of molecular markers for important functional and beneficial genes in breeding. Thirdly, an ontology system is independently produced for knowledge management, and applied to manage the database for DRFG and reference documents. The CRDC platform builts a bridge between biologic data and breeding needs, which is widely used in the domestic and exerts a growing influence.

摘要：

国家水稻数据中心(http://www.ricedata.cn)是一个以水稻为研究对象,融贯多学科的综合性数据平台。它创建了中国水稻品种及其系谱数据库,构建大品种指纹数据集和优异种质数据集,开发“系谱树”和骨干亲本算法;创建了水稻功能基因数据库,以文献析出的方式整合国内外报道的水稻功能基因,开发基于浏览器的遗传图谱生成程序和基因结构图生成程序,构建重要功能基因的分子标记数据集和育种上有利基因的整合数据集;自主开发了用于知识管理的本体系统,开创性地将此系统应用于水稻功能基因数据库和参考文献数据库的管理。平台致力于在生物数据与育种需求之间架起一座桥梁,目前已得到广泛应用,在国内产生重要影响。
