Research Advances of Physiological Effect and Mechanism of Hydrogen Sulfide in Plants
Hydrogen sulfide was the third gas messenger after nitric oxide and carbon monoxide. Recent results indicated that hydrogen sulfide played a very important function in plant physiological processes. In this paper, research advances of hydrogen sulfide biosynthetic pathways in plant, physiological functions and mechanism were summarized, which involved in regulating stomatal closure, seed germination, root development, drought, mineral stress, heat shock, plant disease, regulation of plant senescence and some other physiological processes. Suggestions were put forward that hydrogen sulfide signaling functions and regulation mechanism with modern biotechnologies need more investigation.
