From: Ultraviolet-B enhances the resistance of multiple plant species to lepidopteran insect herbivory through the jasmonic acid pathway

Figure 1

JA pathway is required for UV-B-enhanced Arabidopsis resistance to S. litura. (A) Mean masses (±SE) of S. litura, after 12 days of feeding on control and UV-B-pretreated wild-type (WT), uvr8-2, gs4, and dde2-2 Arabidopsis. Control and UV-B-pre-exposed WT and mutant Arabidopsis were treated with simulated herbivory (SH+) or left untreated (SH−), and the levels of JA (B), JA-Ile (C), and total GSs (D) were determined in samples collected at 2 h (for B and C) or 48 h (for D). For A, n = 30-50; for B–D, n = 6–8. Asterisks (*P < 0.05, **P < 0.01, Student’s t-test) and different letters (P < 0.05, Duncan’s multiple range test) indicate significant differences between treatments within the same genotype.
