摘　　要：硫化氢作为第三种气体信号分子,不仅参与调控植物的正常生理活动,还参与调节植物的重金属胁迫耐性。研究表明,硫化氢可以通过抑制植物对重金属的吸收、转运和吸附,维持植物体内的氧化还原平衡,或通过分室和螯合作用等途径缓解体内重金属离子对植物的影响。在调控植物重金属胁迫耐性过程中,硫化氢常与其他信号分子或者植物激素相互作用,形成调控网络。目前,明确与硫化氢相互作用缓解植物重金属胁迫的植物激素和信号分子有茉莉酸甲酯、水杨酸、乙烯、一氧化氮、甲烷和钙离子等。本文综述了硫化氢与其他信号分子互作缓解植物重金属胁迫生理和分子机制的研究进展,并提出了未来硫化氢调控植物重金属胁迫耐性的研究方向。Hydrogen sulfide(HS)is the third gasotransmitter,which not only involves in regulating normal physiological activity of plants,but also participates in mediating the tolerance for heavy metal stress.Previous studies have shown that HS can alleviate heavy metal stress via inhibiting the absorption,transport and adsorption of metal ions in plants,maintaining the redox balance,and increasing the compartmentalization and chelation of metal ions in plants.In the process of increasing tolerance for heavy metal stress in plants,HS usually interacts with other signaling molecules or phytohormones to form a regulatory network.At present,several phytohormones and signaling molecules have been demonstrated to regulate the relief of heavy metal stress in plants,including methyl jasmonate,salicylic acid,ethylene,nitric oxide,methane,and calcium ion,etc.This paper reviews the research progress of the physiological and molecular mechanisms of HS interacting with other signaling molecules to increase tolerance for heavy metal stress in plants,and puts forward future research directions on HS-regulated tolerance for heavy metal stress in plants.
