摘　要：

硫化氢(hydrogen sulfide, H₂S)是继一氧化氮(nitric oxide, NO)和一氧化碳(carbon monoxide, CO)之后的第三个气体信号分子。近年来, 人们对动物中H₂S的内源性生成、生物学效应及其分子机制等方面进行了广泛研究, 但H₂S在植物中的研究相对较少。本文综述了植物体内H₂S的性质及存在方式、产生途径、在植物生长发育及非生物胁迫下的作用、与其他信号分子的互作等的最新研究进展。

Abstract:

Hydrogen sulfide (H₂S) is considered as the third new member of gasotransmitter family, following nitric oxide (NO) and carbon monoxide (CO). Recently, many researches have been done about the production, biological effect, and molecular mechanisms of H2S in animals, but the researches of H₂S in plants are relatively few. This paper summarized the new research progress in the characteristics, production pathway, functions in plant growth and development and under abiotic stresses, as well as the cross talk with the other signaling molecules of endogenous H2S.

Key words: hydrogen sulfide; gasotransmitter; plant; signaling molecules interactions
