水稻脱粒性的研究进展及展望

The Progress and Prospect of Rice Shattering

水稻是重要的粮食作物,提高水稻产量是水稻育种的重要目标。在水稻驯化中,许多性状朝着有利于增产的方向发展,尤其是水稻脱粒性的变化。相对于野生稻而言,栽培稻倾向于难脱粒的表型。这有效地保证了水稻谷粒的收获,进而提高了水稻产量。为了更好地理解水稻脱粒性,就水稻脱粒的细胞学基础,基因调控机制,植物激素调节做了相关综述,以期为水稻脱粒性的研究提供有用的信息,并在此基础之上对其做了一些展望。

Rice is an important crop, and improving rice yield is an important goal of rice breeding. In the domestication of rice, many traits in favor of yield direction. Especially for rice shattering, compared with wild rice,cultivated rice tends to be difficult to shattering phenotype. This effectively ensured the harvest of rice grain,and thus increased the yield of rice. In or-der to understand rice shattering better,this paper reviewed the cytological basis,gene regulation mechanism and plant hormone regulation of rice shattering. so as to provide useful information for rice shattering study. And on the basis of which we have done some discussion and outlook.
