　　团队研究方向：

　　团队目前的研究领域主要集中在水稻优良种质资源的研究，主要包括：（1）系统地创制和构建优良水稻种质资源和遗传材料；（2）利用基因组学技术克隆控制水稻重要农艺性状的关键基因；（3）通过分子设计培育优良的超级稻品种。

　　Our research concerns the rice germplasm resources, including creating various genetic materials of rice and constructing elite rice germplasm resources, identifying key genes controlling the important agronomic traits of rice, and breeding of super hybrid rice varieties by molecular design.

　　研究进展

　　1）创制了可在实验室内进行大规模的种植和筛选的新型水稻材料“小薇”。

　　We created a new rice germplasm, Xiaowei, which could be used for establishing an ideal indoor research system for rice research.

　　2）揭示了美国稻长粒基因GL7的分子奥秘：GL7位点发生了17.1kb的DNA 大片段串联重复，导致了GL7基因表达量的上升，还引起了其临近的负调控因子表达的下调，引起粒长增加，垩白度和垩白率降低，从而显著改善稻米外观品质。

　　We revealed the functional mechanism of GL7, a grain length controlling gene. Tandem duplication of a 17.1-kb segment at the GL7 locus leads to upregulation of GL7 and downregulation of its nearby negative regulator, resulting in an increase in grain length and improvement of grain appearance quality.

　　3） 利用具有优良性状的日本晴和9311与食用品质较差的超高产品种“特青”配组出若干份高产稻米品质优良的品种。

　　We developed super-rice varieties with both high yield and superior quality by crossing Teqing with both Nipponbare, which is a variety with superior eating and cooking quality but a low yield, and 93-11, which is a variety with excellent appearance quality.
