水稻株型功能基因及其在育种上的应用

The genes controlling rice architecture and its application in breeding

株型是与水稻产量密切相关的重要农艺性状,开展水稻株型功能基因组研究具有重要的现实意义。随着水稻全基因组测序工作的完成,在水稻株型形成的分子机理研究方面取得了一系列重大研究进展。现简要回顾株型的研究历史,分别从株高、叶型、分蘖数目、分蘖角度和穗型方面简要概述在水稻株型形成的分子机理方面取得的研究成果,并简要介绍水稻株型功能基因在育种上的应用情况。

Plant architecture is an important agronomic trait that contributes to rice yield, and thus it is of significance to perform rice functional genomics research on plant architecture. With the completion of rice genome sequencing project, significant progress has been made in elucidating the molecular mechanisms of rice architecture. This review briefly introduces the research history of plant architecture, and summarizes the achievements in elucidating the mechanisms of rice architecture, including plant height, leaf morphology, tiller number, tiller angle and panicle morphology. Finally, we give a brief overview on application of key genes in rice breeding.
