Plant damage of Col-0 and Kon genotypes infested with T. urticae and mite performance. A, Leaf damage on the Arabidopsis mutant Col-0 Salk line (pp2a5) as well as Col-PP2-A5 (PP2-A5_1.1, PP2-A5-2.3, and PP2-A5_4.1) and Kon-PP2-A5 (PP2-A5_1.2, PP2-A5-4.1, and PP2-A5_5.3) overexpressing lines and Col-0 and Kon wild type (WT), relative to nontransformed Col-0 wild type, 4 d after infestation. Data are means ± se of six independent plants. B, Effects of silencing and overexpression of PP2-A5 in Arabidopsis Col-0 or Kon plants on mite mortality. Data are means ± se of eight independent plants. For A and B, different letters indicate significant differences (P < 0.05, one-way ANOVA followed by Tukey’s test). C, Correlation among mite mortality and leaf damage (P < 0.05, Pearson product moment).
