Hydrogen sulphide (H S) is a gaseous molecule and originates endogenously in plants. It is considered a potential signalling agent in various physiological processes of plants. Numerous reports have examined the role of H S in fruit ripening and in enhancing fruit quality traits. H S coordinates the fruit antioxidant system, fruit ripening phytohormones, such as ethylene and abscisic acid, together with other ripening-related signalling molecules, including nitric oxide and hydrogen peroxide. Although many studies have increased understanding of various aspects of this complex network, there is a gap in understanding crosstalk of H S with key players of fruit ripening, postharvest senescence and fruit metabolism. This review focused on deciphering fruit H S metabolism, signalling and its interaction with other ripening-related signalling molecules during fruit ripening and postharvest storage. Moreover, we also discuss how H S can be used as a tool for improving fruit quality and productivity and reducing postharvest loss of perishable fruits.
硫化氢（H₂S）是一种气态分子，在植物体内内源性产生。它被认为是植物各种生理过程中的一种潜在信号传导因子。众多报告研究了H₂S在果实成熟和改善果实品质性状方面的作用。H₂S协调果实抗氧化系统、果实成熟植物激素，如乙烯和脱落酸，以及其他与成熟相关的信号分子，包括一氧化氮和过氧化氢。尽管许多研究增进了对这个复杂网络各个方面的理解，但在理解H₂S与果实成熟、采后衰老和果实代谢的关键参与者之间的相互作用方面仍存在差距。本综述着重于解读果实H₂S代谢、信号传导及其在果实成熟和采后贮藏期间与其他成熟相关信号分子的相互作用。此外，我们还讨论了H₂S如何用作改善果实品质和生产力以及减少易腐果实采后损失的工具。
