The metabolism of signal molecule hydrogen sulifde and its role in the acquisi-tion of heat tolerance in plants
High temperature is a major factor that limits growth, development and production in plants. Hydro-gen sulfide (H2S) is a third endogenous gaseous signal molecule after carbon monoxide (CO) and nitric oxide (NO) in plants, involving in many physiological processes such as seed germination, growth and development, stomatal movement, and stress tolerance including heat tolerance. On the basis of current research advance, in this review, H2S metabolism, H2S-induced heat tolerance and involvement of antioxidant system, osmolyte, cal-cium messenger system and heat shock proteins, as well as signal crosstalk between H2S and other signal mole-cules like NO, hydrogen peroxide, CO, abscisic acid, salicylic acid in the acquisition of heat tolerance induced by H2S were summarized, which indicated that H2S was an important signal molecule in the acquisition of heat tolerance of plants, and research direction in the future was prospected.
