英文摘要	the influence of cadmium on growth, cadmium accumulation, composition, and content of glucosinolates was investigated in arabidopsis thaliana after 4 weeks of growth in hydroponics. accumulation of 3,820 and 321 mu g cd g(-1) dry weight in the roots and leaves of a. thaliana, respectively, exposed to 50 mu m cd. cadmium treatment significantly decreased the total concentration of glucosinolates both in the leaves and roots. cd-induced alteration of total glucosinolate content in the roots was mainly due to the decrease of indolyl-glucosinolates. in the cd treatment leaves, significant decreases were, respectively, detected for glucoibervirin and 4-methoxyglucobrassicin (p < 0.01), while other glucosinolate levels did not decrease significantly. in response to cadmium, the three indolyl-glucosinolates all showed significant decreases in the roots. the distinctive influence of cadmium on glucosinolate profiles in cd-sensitive a. thaliana may be of great ecological importance, decreasing the resistance to phytophage attack. taken together, our data is discussed in relation to jasmonic acid and salicylic acid as possible molecules that modulate the alteration of glucosinolate profiles in response to cadmium. the similar effects of cd treatment on the levels of individual glucosinolates in leaves and roots were observed at higher-concentration cadmium treatment (100 mu m cd).
