摘要:
The contamination of soil by cadmium (Cd) is a widely concerned environmental problem threatening plant growth and human health. The essential nutrient sulfur plays a crucial role in plant responses to Cd stress. Cysteine (Cys) is the first product of sulfur assimilation and plays a cardinal role for detoxicating heavy metals in plants. Brown mustard (Brassica juncea (L.) Czern) has good application prospect in phytoremediation of heavy metals-polluted soil due to its high enrichment capacity for multiple heavy metals. However, the effect of exogenous Cys in mitigating Cd toxicity in B. juncea...
