摘　　要：水稻(Oryza sativa L.)是重要的粮食作物,其产量与粮食安全和经济发展密切相关。水稻抽穗期是一个重要的农艺性状,对水稻播种季节、产量和适宜种植地区有着极其重要的影响。水稻抽穗期的调控涉及了一系列的基因,而且这些基因彼此之间存在着复杂的相互调控关系。盐、干旱和温度等非生物胁迫严重影响水稻抽穗期,解析非生物胁迫对水稻抽穗期的影响及其分子机理,有助于抗逆水稻新品种的选育。本研究梳理了水稻抽穗期调控的分子机制,以及非生物胁迫对水稻抽穗期的影响,以期为水稻耐逆品种的选育提供理论指导。As one of the most important staple food crops,rice(Oryza sativa L.)yield influences food security and economic development.Heading date is one of agronomic traits in rice,and directly controls seed-sowing stage,yield,and regional adaptability.Heading date is a complex trait controlled by multiple genes.Moreover,there are complicated interactions among these genes.Heading date is significantly influenced by abiotic stresses,such as salt,drought and temperature.Exploring the effects of abiotic stresses on the rice heading date and the underlying molecular mechanism contributes to breeding new varieties with high abiotic stress-tolerance.Herein,we discuss the molecular mechanism controlling rice heading date and the effects of abiotic stresses on heading date,which provides important information for breeding rice new varieties with high resistance.
