摘要
水稻落粒性的丧失是水稻人工驯化中的重要事件。容易落粒是导致水稻减产的主要因素之一,因此落粒性也是水稻育种项目中重点选择的性状。为了阐明落粒性的机理,许多研究者开展了水稻落粒性有关基因的定位和克隆研究。其中,2个控制水稻落粒性的基因(sh4,qSH1)已经被克隆。本文综述了水稻落粒性的基因定位、克隆及进化等方面的研究进展。
Loss of seed shattering is a key event in the domestication of rice. Easy shattering is the major cause of grain loss and remains an emphasis on selection for the loss of seed shattering habit in most rice breeding programs today. In order to elucidate the mechanism for seed shattering, results on gene mapping and cloning for seed shattering related trait were increasingly documented in recent years, and two genes for seed shattering were successfully cloned. Here we summarized the current progresses on the mapping, cloning and evolution studies for seed shattering trait in rice.
