Expression ratios of <i>FMO_GS-OX2</i> in leaves subjected to different oviposition and feeding treatments.

<p>Values are means ± standard errors of wild-type <i>Arabidopsis thaliana</i> plants (Col-0). C: untreated control leaves (<i>N</i> = 8); E: leaves on which eggs were laid and left for 5 days (<i>N</i> = 8); E+F: leaves on which eggs were laid and caterpillars hatched and fed for 2 days (<i>N</i> = 7); F: leaves that never had eggs but were fed on for 2 days (<i>N</i> = 7). Data were normalised to the amplification of ubiquitin, calibrated against the value of the control, and statistically evaluated by analyses of variance (ANOVA). Different letters above the columns indicate significant differences by means of Fisher's LSD test for <i>post hoc</i> comparisons (<i>P</i><0.05).
