ABSTRACT
Cadmium (Cd) is a poisonous element for human health. This study was conducted to explore whether H2S can alleviate the toxic effects of Cd on ginger. Specifically, ginger plants were grown in soil and treated with 7.5 mg·l-1 CdCl2, after which water (T1), 0.8 mM NaHS (T2), or 0.8 mM NaHS and 0.15 mM HT (T3) were added to the soil. The application of NaHS increased the activities of antioxidant enzymes (APX, GR, MDHAR, and DHAR) during the early treatment stage. It also inhibited the decrease in Pn, Gs, and Ls under Cd stress conditions while also limiting the increase in Ci. An analysis of the expression of Cd uptake-related genes indicated that NaHS upregulated the expression of ZoNramp1, which encodes a metal transporter, in roots as well as ZoPCS1, which encodes a phytochelatin synthase. In contrast, NaHS downregulated ZoHMA2 expression in the rhizomes and roots under Cd stress conditions.
