(A) Effect of P. indica on the spatial accumulation of Cd in different tissues of tobacco seedlings. The bars represent the means ± SDs, n = 3. Different letters on the bars mean significant differences at p < 0.001 (t-test). (B) The subcellular proportion of Cd in tobacco roots and leaves with P. indica inoculation or not. (C,D) The effect of P. indica on the antioxidant levels in tobacco under Cd stress. The bars represent the means ± SDs, n = 3. Significant differences (t-test): * means p < 0.05, *** means p < 0.001, **** means p < 0.0001.
