Fig. 3From: Comparative transcriptomic and metabolic analysis of wild and domesticated wheat genotypes reveals differences in chemical and physical defense responses against aphidsPhysiological characterization of the three genotypes including ROS, total chlorophyll levels, and water content. a DAB staining of hydrogen peroxide levels in the wheat leaves. Upper panel: DAB solution; lower panel: Na2HPO4 solution, which was applied as a control treatment. b Total chlorophyll content in leaves of wheat plants (mean ± SE, n = 5). c The relative water content of three wheat cultivars (mean values ± SE, n = 5). Different letters above the bars indicate significant differences (P value < 0.05), one-way ANOVA using the Tukey-Kramer HSD testBack to article page
