Hydrogen Sulfide in Plant Biology

Abstract

Hydrogen sulfide (H2S) has been recognized as an important signaling molecule in animal cells, and accumulating data suggest it is also a signal involved in various physiological processes in plants alongside with other reactive compounds such as hydrogen peroxide (H2O2) and nitric oxide (NO). The enzyme system which generates H2S and removes it has been studied in both animal cells and plants. In this section, the effects of H2S on plant growth, development, and stress resistance toward heavy metals, salt, drought, etc. are reviewed, and future perspectives are discussed.
