Glutathioneinduced hydrogen sulfide enhances drought tolerance in sweet pepper (Capsicum annuum L.)

Glutathione (GSH) has been studied for its potential to enhance stress tolerance in plant systems, but the role of hydrogen sulfide (H2S) in GSH- induced water stress tolerance in sweet pepper (Capsicum annuum L.) is still under investi- gation. This study explores how H2S and GSH modulate water stress tolerance in pepper plants, addressing a research gap. The joint effect of sodium hydro- sulfide (NaHS), a donor of H2S, and GSH on water stress tolerance was deter- mined through pre-treatment...
