Fig. 8From: Comparative transcriptome and histological analyses of wheat in response to phytotoxic aphid Schizaphis graminum and non-phytotoxic aphid Sitobion avenae feedingEffects of S. graminum and S. avenae feeding on the activities of POD, SOD, CAT and APx in wheat leaves at different time points. The values are presented as means ± SE of three biological replicates. Leaves without aphid infestation at 0 h were set as control groups. Asterisks indicate the mean values are significantly different between the aphid-infested and control plants (P < 0.05)Back to article page
