Fig. 1From: Differential tissue accumulation of 2,3,7,8-Tetrachlorinated dibenzo-p-dioxin in Arabidopsis thaliana affects plant chronology, lipid metabolism and seed yieldDetection and quantification of TCDD in Arabidopsis tissues by HR/GC-MS. Plants were grown for 30-days in glass tubes containing MS media supplemented with various concentrations of TCDD 0, 10, 50 and 100 ng L−1. In each treatment, shoots and roots of plant were taken and subjected separately to the extraction and analysis of TCDD. Concentration of TCDD in plant tissues was expressed as pg g−1 fresh weight. Inset, a representative HR/GC-MS diagram indicating the peak of TCDD (Retention time ≈ 5.22) in the plant extract. Three measurements were done for three individual plants. Data are mean values ± SD (n = 6)Back to article page
