Fig 3

To analyze the expression of B. rapa Cd tolerance genes (BrMTs and BrPCSs), qRT-PCR was performed with cDNA synthesized from total RNA as a template and gene-specific primers (S1 Table). The expression levels of Cd tolerance genes were normalized to the level of actin, and the values indicate the average and standard error (biological replicates: 3). Different letters indicate that the means (between various samples) are significantly different by the Tukey HSD test (P≤0.05). R, roots from one-month old plants; RL, rosette leaves from one-month old plants; Fl, flower; AL, leaf from flowering plants; St, stem from flowering plants.
