Abstract
In mammalian cells, hydrogen sulfide (H2S) has been identified as the third gasotransmitter after nitric oxide and carbon monoxide. Overwhelming evidence has proven that H2S also participates in diverse physiological and biochemical processes within the organism and exert specific functions in plants. A number of reports illustrated that H2S could improve plants ability of adapting to the multiple environmental stimuli by alleviating injuries and toxicities caused by the stressful conditions. It also participated in specific physiological, developmental and metabolic processes, such as the regulation of stomatal movement and drought tolerance, senescence and maturation, and lateral root formation. In this article, latest research progresses in biosynthetic and metabolic pathways of H2S in plants as well as corresponding physiological functions were summarized. We also discussed the potential molecular mechanism of interaction between H2S and other signaling molecules as well as the H2S-modifying protein activities. Finally, we prospected possible future work for H2S in plants.
