Feeding assay of Spodoptera littoralis larvae on Arabidopsis WT and pop2-5 plants. S. littoralis first instar larvae were pre-weighed and three larvae were placed on each plant. The larval weight (mean ± SE) was measured after 7 days of feeding. (A) Final weight of larvae after feeding for 1 week on WT (white) and pop2-5 (black) plants. The total number of larvae weighed (N) is indicated in the bars. (B) Larval macroscopic view after 1 week of feeding on the indicated mutants. Experiments were repeated three times independently. Significant differences between WT and GABA mutant plants after feeding were analyzed by Student’s t-test (∗∗∗P ≤ 0.001).
