Interaction between hydrogen sulfide and hormones in plant physiological responses

The gasotransmitter, hydrogen sulfide (H2S) is involved in plant growth and development, and stress responses. Plant hormones influence the levels of endogenous H2S and H2S may affect the biosynthesis, transport, and signal transduction of different phytohormones. The dual role of H2S in the interaction with phytohormones contributes to the physiological functions of H2S in the life cycle and responses to abiotic stresses in plants. The biological effect of H2S might depend on the ratio between phytohormones. However, the mechanism by which H2S and plant hormones interplay in plants remains fragmentary. This review summarized the biosynthesis and degradation of H2S and discussed the cross-talk between H2S and different phytohormones along with the future perspectives.
