Progress in research on the physiological and molecular mechanisms of seed dormancy in legumes
摘要
Abstract
Seed dormancy is an adaptive trait that developed during long-term evolution,enabling plants to survive under adverse conditions.Legumes are a core crop group in global agricultural production(encompassing food,forage,and green manure),and the dormancy characteristics of their seeds directly affect sowing quality,field emergence rate,and yield stability.The molecular regulation of seed dormancy in legumes primarily revolves around the balance between abscisic acid(ABA)and gibberellin(GA)levels,involving a complex system that integrates the expression of genes involved in seed coat development and transcription factor networks,as well as epigenetic modifications and environmental signals.This mechanism ensures seed survival under unfavorable conditions while enabling precise germination under suitable circumstances.Physiological dormancy is the primary factor in seed dormancy,where ABA and GA do not directly interact but instead exhibit antagonistic effects-ABA promotes"dormancy maintenance"while GA triggers"germination initiation".In Arabidopsis thaliana,many downstream targets of the ABA-responsive germination inhibitor ABI3 have been identified,including the ABI5,DELLA,and bHLH transcription factors.However,the corresponding regulatory network in legumes remains unclear,and further research is required to explore the interactions between ABI3 and other factors in the ABA signaling pathway.Based on recent research,this paper systematically reviews the types of seed dormancy in legumes,dormancy-breaking techniques,and molecular regulatory networks,with a focus on legume-specific dormancy traits.Furthermore,drawing on advances in research on the molecular regulation of seed dormancy in model plants,we propose a hypothetical model for the molecular regulation of seed dormancy in legumes.This review provides a theoretical foundation for understanding the molecular mechanisms of seed dormancy in legumes while offering insights for cultivation practices and varietal improvement.关键词
