Transcript levels of TPS10 and TPS10M are high in transgenic lines and stable across several treatments (mean ± sem, n = 4). Transcripts were quantified in the first fully expanded leaf (+1) in two lines of TPS10 (A), two lines of TPS10M (B), or line M-1 1 h after treatment with herbivory-related elicitors (C), which did not change TPS10M transcript abundance (P = 0.491 in a Kruskal-Wallis test across treatments). Similarly, no effect of treatment was observed on transcripts in the other lines in separate experiments (not shown). There was a very low signal caused by nonspecific amplification in wild-type (WT) negative controls (not detected [nd] < 0.001 units), which increased to a maximum of approximately 0.03 units after W+OS treatment. *, P < 0.05; **, P < 0.01; ***, P < 0.001 after Holm-Bonferroni correction of Welch’s t tests versus the wild type (the wild type was tested two times in A and B, and M-1 was tested two times in C).
