H₂S-mediated balance regulation of stomatal and non-stomatal factors responding to drought stress in Chinese cabbage.

ABSTRACT: Increased evidence has shown that hydrogen sulfide (H₂S), a novel gasotransmitter, could enhance drought resistance in plants by inducing stomatal closure, with concurrent enhancement of photosynthetic efficiency, but little is known about the mechanism behind this contradictory phenomenon. This study examined the regulating mechanism of H₂S in response to drought stress from stomatal and non-stomatal factors in Chinese cabbage. The results showed that exogenous H₂S could increase the accumulation of photosynthetic pigments and alleviate the damage caused by drought stress. It also regulated the expression in transcriptional level and the activity of ribulose 1,5-bisphosphate carboxylase/oxygenase (BrRuBisCO) under drought stress. The large subunit of BrRuB
