种子休眠及其调控机制研究进展
Advance on Seed Dormancy and Its Regulation Mechanism
摘要
Abstract
Seed dormancy is defined as the inability of seeds to germinate in favorable conditions,which can prevent pre-harvest germination of crops.Studying seed dormancy in forestry is beneficial to forest cultivation.Studies showed that the plant hormone abscisic acid(ABA)induces and maintains seed dormancy,while gibberellin(GA)breaks dormancy.The two hormones regulate seed dormancy and germination in an antagonistic manner.Although some studies have investigated the hormonal regulation of seed dormancy and germination,there is a lack of a systematic summary of the molecular mechanisms underlying seed dormancy.Therefore,this review provides an overview of the types of seed dormancy and the effects of light and temperature signals on seed dormancy.It focuses on the regulatory mechanisms of seed dormancy by ABA,GA,and the interactions between these hormones.Additionally,it summarizes the research on dormancy-specific regulatory factors(such as DOG1,DOG18,Sdr4)and epigenetic regulation mechanisms.The aim is to deepen the understanding of the complex regulatory network of seed dormancy and provide theoretical references for plant trait improvement and selective molecular breeding.关键词
