Figure 4From: Jasmonate-dependent induction of polyphenol oxidase activity in tomato foliage is important for defense against Spodoptera exigua but not against Manduca sextaS. exigua larvae perform better on jai1 mutants than on wild type. The experiment involved 300 and 150 four-day-old larvae on wild-type and jai1 plants, respectively. (A) Percent survival of S. exigua larvae on wild type (WT2, Castlemart, blue) and the jai1 mutant (yellow). (B) Larval development on wild-type (blue) and jai1 (yellow) host plants. Larval mass is given in mg as the mean +/- SD. Asterisks indicate significant differences (Wilcoxon signed rank test: *** P < 0.001). (C) S. exigua larvae at the end of the experiment, prior to pupation (scale bar = 1 cm).Back to article page
