Abstract: Vetch (Vicia) forage species possess significant forage value and ecological functions. In the context of global climate change, abiotic stresses such as low temperature, drought, salinity, and heavy metal contamination pose severe challenges to their growth, development, yield formation, and safe utilization. Considerable research progresses on the stress resistance physiology and molecular regulatory mechanisms of vetch forage have been reported in recent years. Notable advances have been made in understanding their adaptive responses to stresses through osmotic regulation, antioxidant defense, hormonal signaling, ion homeostasis, and related gene regulatory networks. However, most existing studies have focused on single stress conditions and are limited to a few species such as common vetch (Vicia sativa). Knowledge regarding the responses of vetch plants to combined stresses, the genetic basis of stress-resistant traits, and systematic regulatory mechanisms remains insufficient. This review systematically summarized research progress on vetch forage under abiotic stresses, including low temperature, drought, salinity, and heavy metal stress. It highlighted key physiological adaptive features and molecular regulatory patterns, and discussed future directions for stress resistance improvement and molecular breeding in light of emerging research trends such as multi-omics integration, combined stress analysis, and rhizosphere microbial interactions. The aim is to provides insights for the development of stress-resistant germplasm and the efficient utilization of vetch forage resources.

摘要: 野豌豆属(Vicia)牧草兼具饲用价值与生态功能。随着全球气候变化,低温、干旱、盐碱及重金属等非生物胁迫对野豌豆属牧草的生长发育、产量形成以及安全利用构成了严峻挑战。近年来,围绕野豌豆属牧草抗逆生理与分子调控机制的研究不断推进,在野豌豆属牧草适应逆境渗透调节、抗氧化防御、激素信号调控、离子稳态维持及相关基因网络调控等方面取得了良好进展。然而,现有研究多集中于单一胁迫条件,研究也多集中在箭筈豌豆(Vicia sativa)等少数物种,对野豌豆属植物响应多重胁迫、抗逆性状遗传基础及系统调控机制的认识仍显不足。本文系统综述了野豌豆属牧草在低温、干旱、盐碱和重金属胁迫等非生物胁迫下的研究进展,重点归纳其适应逆境的主要生理调节特征与分子调控模式,并结合多组学整合、复合胁迫解析及根际微生物互作等研究趋势,对未来抗逆改良与分子育种方向进行了展望,以期为野豌豆属牧草抗逆种质创新与资源高效利用提供参考。
