摘要 器官脱落是植物生命过程中重要的生理现象。植物体内的许多激素和非激素类物质(扩展蛋白、H2O2、细胞壁水解酶等)都参与脱落过程的调控,而且是相互协同配合,共同发挥作用。本文综述了生长素、乙烯、脱落酸、赤霉素和茉莉酸等植物激素,以及非激素类物质扩展蛋白、H2O2和两种主要的细胞壁水解酶(纤维素酶和多聚半乳糖醛酸酶)在植物器官脱落过程中的调控作用,并对它们在植物器官脱落调控中的相互作用进行分析,以期为相关研究提供信息。 Abscission is an important developmental event in the life cycle of higher plant.There are many kinds of substances regulating the process of abscission.For example,plant hormones,expansins,H2O2 and cell wall hydrolases etc.Each substance must interact with others to regulate abscission,and all of them constitute a complex net work.This review details the roles of hormones and other regulating substances in abscission,including indole acetic acid(IAA),ethylene,abscisic acid(ABA),gibberellin(GA),jasmonic acid(JA),expansins,H2O2,two most important cell wall hydrolases cellulase and polygalacturonase(PG).Finally,analyze the interaction of them to provide more information for further research in this field.
