摘要/Abstract

摘要： 种子是植物的繁殖器官，也是农作物的主要收获部分，因此种子的正常发育对于保障人类的粮食安全至关重要。被子植物种子由胚、胚乳和种皮3部分组成，其发育过程受不同信号通路的调控。其中植物激素对于种子各组织发育有着至关重要的影响，是调节种子发育的重要因素。将生长素、细胞分裂素、赤霉素和油菜素内酯4类植物激素作为重点，对其调控网络的分子机制进行梳理，综述了模式植物拟南芥及其他作物种子发育相关基因的研究进展，总结了特定基因对胚、胚乳及种皮发育的作用机理，讨论了种子发育进程的分子机制与植物育种的发展，为了解被子植物种子发育的激素调控机理及作物的品质改良和产量提升提供理论依据。
