Metabolomics analysis reveals different mechanisms of cadmium response and functions of reduced glutathione in cadmium detoxification in the Chinese cabbage

Chinese cabbage (Brassica rapa) is one of the vegetable crops with largest acreage and yield in East Asia. With aggravation heavy metal pollution soil, excessive accumulation has become increasingly severe cabbage, among which, cadmium most representative elements. It critical to understand regulatory mechanism Cadmium (Cd) response tolerance at metabolism level. Comparative functional metabolomics transcript analyses were conducted grown on half-strength MS solid medium different Cd concentrations (5, 25, 100 µM Cd). The results revealed that responses not consistent metabolic responses, treatment could induce more specific differentially expressed metabolites. Moreover, reduced glutathione (GSH) pathway was induced under higher stresses (25, following result indicated GSH played a role reduction but led low stress. This study offers information handling contamination cabbages conditions. Different concentration resulted accumulate stress, exclude cabbage.
