FIGURE 9.

Diet test conducted with bacterially expressed and purified Arabidopsis Kunitz-PI;1 and commercially available soybean trypsin inhibitor. (A) Survival rates of nutrient-starved pillbugs on Kunitz-PI;1 and soybean trypsin inhibitor diets. For control (Ctr), a senescent Arabidopsis leave was used as diet. (B) as (A), but depicting the results for nutrient-starved woodlice on Kunitz-PI;1 and soybean trypsin inhibitor versus control diets. Asterisks indicate statistically significant changes compared with the corresponding WT sample for each condition calculated by a two-tailed Student’s t-test; ^∗∗∗P < 0.001 (cf. Supplementary Table S2).
