Fig. 2From: Comparative transcriptome and histological analyses of wheat in response to phytotoxic aphid Schizaphis graminum and non-phytotoxic aphid Sitobion avenae feedingChlorophyll content of wheat leaves after aphid infestation. Control: untreated leaves; Sa48h: leaves infested with S. avenae for 48 h; Sg48h: leaves infested with S. graminum for 48 h. The values are presented as means ± SE of three biological replicates. Different letters indicate significant differences among treatments (P < 0.05, ANOVA)Back to article page
