Abstract

Hydrogen sulphide (H2S) is emerging as an important gaseous molecule involved in various plant developmental processes and plant stress responses. In this study, exogenous H2S donor (sodium hydrosulfide, NaHS) treated wheat plants were used to investigate the role of H2S in response to iron-deficiency. The results showed that H2S significantly alleviated leaf chlorosis under iron-deficient conditions, and thus improved photosynthesis. Moreover, H2S increased the lateral root (LR) number, density and length of wheat seedlings grown in iron-sufficient and deficient culture solution, and promoted phytosiderophores (PSs) secretion from roots simultaneously, which eventually led to an increase in iron uptake. Taken together, these results indicate that H2S improved iron uptake by regulating root development and PSs secretion, and consequently increased chlorophyll biosynthesis and photosynthesis in plants under iron-deficiency.
