NATA1 Effects on P. rapae and P. xylostella Growth.

(A) NATA1 gene expression 3 d after one neonate caterpillar was placed on a 3-week-old Arabidopsis plant. Gene expression on control plants without caterpillars was set to 1.

(B) N^δ-acetylornithine accumulation 7 d after one neonate caterpillar was placed on a 3-week-old Arabidopsis plant.

(C) P. rapae dry weight 7 d after neonate larvae were placed on wild-type Col-0 or nata1-1.

(D) Pupal weight of P. xylostella that spent their entire larval growth on Col-0 or nata1-1. P values calculated with t tests. *P < 0.05, t test relative to controls. Numbers in bars indicate sample sizes ± se. ND, not detected.
