Root enhancement in cytokinin-deficient oilseed rape causes leaf mineral enrichment, increases the chlorophyll concentration under nutrient limitation and enhances the phytoremediation capacity

Table 1 Cytokinin content of 8-d-old Brassica napus seedlings overexpressing the CKX2 gene. The concentration of cytokinin metabolites was measured in root, shoot and whole seedlings of the lines 35S:CKX2-1, 35S:CKX2-4, 35S:CKX2-13, and wild type. The cytokinin metabolite concentrations detected in the transgenic lines are shown as percent of those found in wild type. Absolute values and statistical analysis are shown in Additional file 1: Table S1. Percentage printed in bold indicates statistically significant differences (p < 0.05) as compared to wild type calculated by Student’s t-test
