| 摘 要： | 水稻是重要的粮食作物,全球有超过50%的人口以稻米作为主食。同时水稻又作为一种模式生物被各大研究机构所研究。水稻披垂叶突变体是由于控制水稻中脉形成的基因发生突变,导致基因发生功能缺失,使水稻叶片中脉的形成不能正常进行,从而出现披垂叶的性状。目前已经发现2个基因位点与水稻中脉形成有关,DL和DL2基因正是这2个不同的位点。研究水稻披垂叶突变基因,对研究水稻叶中脉的形成以及水稻理想株型的选育有重要的意义。对水稻披垂叶突变基因的研究进展进行综述,以对水稻这一类特殊株型得到更好地了解。

| Abstract: | Rice is an important food crop in the world, with a population of over 50% people with rice as the staple food.At the same time, rice as a model organism is studied by major research institutes .Rice drooping leaf mutants was due to the formation of rice midrib gene muta-tion, gene deletion can lead to the formation of power, can not be normal in rice leaves midrib, which appeared drooping leaf characters.It was found that two gene loci formed with rice DL and DL2 genes on midvein, they were the two different sites.The research of rice drooping leaf mutant gene, has focused on the formation of the research of rice leaf midrib and breeding of rice ideotype .In this paper, we will review the research progress of rice drooping leaf mutant genes, and hope to get a better understanding of the specific plant types of rice. |
