Expression of two xenobiotic metabolism genes in S. flava negatively correlates with the defensive potential of their host plants. The xenobiotic metabolism genes Peritrophin A and Glutathione S-transferase D1 (GstD1) are expressed at higher levels in S. flava larvae feeding on the rbohD and rbohF Arabidopsis mutants and at lower levels in larvae feeding on the asFBP1.1 mutant. This correlates with the lower potential for reactive oxygen species (ROS) formation in asFBP1.1, and with the enhanced propensity for programmed cell death and concomitant release of ROS and other defensive chemicals in rbohD and rbohF. The figure shows the expression of Peritrophin A and GstD1 relative to the control housekeeping gene RpL32 in larvae reared on Arabidopsis mutants compared to wild-type (Col-0) plants. Error bars represent standard error of the mean. Capital letters indicate statistically significant differences in gene expression between larvae feeding on mutant plants compared to those feeding on WT plants; lowercase letters indicate statistically significant differences in gene expression between larvae feeding on the asFBP1.1 mutant and larvae feeding on the rbohD and -F mutants (one-way ANOVA with post hoc Tukey’s HSD tests; P < 0.05).
