Figure 5. Expression patterns of three key genes encoding proteins involved in divalent cation uptake (ZIP), detoxification (PCS), transport (MTP) in roots and leaves of non-inoculated (-DSE) or inoculated (+DSE) maize exposed to 0, 10, 50, 100 mg kg⁻¹ Cd²⁺ for 30 days.

Different letters on the bars indicate significant difference between the treatments (Tukey’s HSD, p < 0.05).
