摘　　要：抽穗期作为水稻的重要农艺性状,是决定其生长发育和产量形成的关键因素之一。光周期是影响水稻抽穗的主要环境因素,近年来,随着表观遗传修饰与环境因素交叉作用研究的不断增多,光周期调节水稻抽穗的分子机理及调控机制得到进一步完善。本文综述了光周期调节水稻抽穗的2个主要途径及其相关基因功能、表观遗传在光周期调控水稻抽穗的作用及外界因素对光周期途径的影响,为深入理解水稻抽穗的调控机理以及水稻种质改良和生产管理提供参考。As an important agronomic trait of rice,heading date is one of the key factors that determine its growth and development and yield formation.Photoperiod is a major environmental factor affecting rice heading.In recent years,with the increasing of studies on the cross effects of epigenetic modification and environmental factors,the molecular mechanism and regulatory mechanism of photoperiod regulating rice heading have been further improved.In this paper,we reviewed the two main pathways of photoperiodic regulation of rice heading and the functions of related genes,the role of epigenetics in photoperiodic regulation of rice heading,and the influence of external factors on photoperiodic pathway,so as to provide references for understanding of the regulatory mechanism of rice heading,as well as the improvement and production management of rice high-yield germplasms.
