摘要
Hydrogen sulfide (H2S), a gaseous transmitter, has long been considered as a phytotoxin, but nowadays as a small molecule with multiple functions fulfilled at low concentrations. H2S has many positive effects on plant growth, development, and the acquisition of plant stress tolerance. The focus of this review is to summarize the generation and properties of hydrogen sulfide and its potential physiological functions, including mediating stomatal movements; mediating the responses to abiotic stressors, such as heavy metals, salt, drought, and heating; involving in organogenesis and growth; regulating senescence; priming seed germination; and enhancing photosynthesis. Future prospects are also presented.
