Hydrogen sulphide (H2S) is a gaseous molecule that is endogenously produced in plants and is considered a potential signaling agent in physiological processes. Many studies have explored the role of H2S in fruit ripening and quality enhancement, but there is still a gap in understanding the crosstalk of H2S with key players in fruit ripening, postharvest senescence, and fruit metabolism.
Hydrogen sulphide (H2S) 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 H2S in fruit ripening and in enhancing fruit quality traits. H2S 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 H2S with key players of fruit ripening, postharvest senescence and fruit metabolism. This review focused on deciphering fruit H2S metabolism, signalling and its interaction with other ripening-related signalling molecules during fruit ripening and postharvest storage. Moreover, we also discuss how H2S can be used as a tool for improving fruit quality and productivity and reducing postharvest loss of perishable fruits.
