| 英文摘要 | the metabolic responses of arabidopsis thaliana to cadmium exposure was characterized in this study. a. thaliana was cultivated in medium contaminated with different cadmium concentrations (0, 5 and 50 mu m, respectively) for 2 weeks. metabolite analyses were performed using gas chromatography-mass spectrometry. more than 80 metabolites characterized by retention time indices and specific mass fragments were identified. the levels of carbohydrates, organic acids, amino acids, and other stress-responsive metabolites changed under cadmium stress. treated plants showed increased levels of ala, beta-ala, pro, set, putrescine, suc and other metabolites with compatible solute-like properties, notably 4-aminobutyric acid, glycerol, raffinose and trehalose, compared to control (untreated) plants. studies indicated that concentrations of antioxidants (alfa-tocopherol, campesterol, beta-sitosterol and isoflavone) also increased significantly. these results confirm the important role of antioxidant defences in the mechanisms of plant-resistance to cadmium stress. our results suggested that metabolic profiling is a powerful tool that can rapidly classify environmentally modified plants and simplify the process of cadmium-stress responses. these data will be helpful for better understanding of mechanisms of plant adaptation to cadmium stress at the metabolite level.
