Research Progress on Hydrogen Sulfide Signaling in Plants
Hydrogen sulfide (H2S) has been proposed as the third gasotransmitter after nitric oxide (NO)and carbon monoxide (CO),whose production and physiological functions in mammals have been fully confirmed,thus making it a hot research area.In recent years,great improvement has also been achieved with respect to the studies on H2S synthesis and function in plants.For example,several endogenous genes encoding H2S-generating enzymes have been cloned,detecting techniques of chemical signals have developed rapidly,the research on the growth and development process and stress responses has been going on,the interactions with different plant hormones and other signaling molecules have also been reported successively.This paper summarized the research progress on the production,detection of endogenous H2S,its physiological functions and signal transduction pathways,etc.Meanwhile,the current problems and future insights in this field were presented.
