Fig. 7From: The endophytic bacterium Sphingomonas SaMR12 alleviates Cd stress in oilseed rape through regulation of the GSH-AsA cycle and antioxidative enzymesThe effect of Sphingomonas SaMR12 on plant (a) SOD activity, (b) POD activity. (c) CAT activity and (d) APX activity in both shoots and roots. The solid line, non-inoculated plants; the dashed line, SaMR12-inoculated plants. Plant samples were harvested after 7 d of treatment. The vertical line on each bar shows the standard deviation (n = 3). The different letters on the error bars indicate significant differences among treatments at p < 0.05 in the shoot and the root, respectively. The same letters above the bars indicate no difference between the treatments at p < 0.05. Asterisk (*) and double asterisks (**) indicate p < 0.05 and p < 0.01, respectively, for Student’s t-test carried out between SaMR12 non-inoculated and SaMR12-inoculated samplesBack to article page
