Comparative Proteomic Analysis Reveals the Regulatory Effects of H₂S on Salt Tolerance of Mangrove Plant Kandelia obovata.

ABSTRACT: As a dominant mangrove species, Kandelia obovata is distributed in an intertidal marsh with an active H₂S release. Whether H₂S participates in the salt tolerance of mangrove plants is still ambiguous, although increasing evidence has demonstrated that H₂S functions in plant responses to multiple abiotic stresses. In this study, NaHS was used as an H₂S donor to investigate the regulatory mechanism of H₂S on the salt tolerance of K. obovata seedlings by using a combined physiological and proteomic analysis. The results showed that the reduction in photosynthesis (Pn) caused by 400 mM of NaCl was recovered by the addition of NaHS (200 μM). Furthermore, the application of H₂S enhanced the quantum efficiency of phot
