Fig. 2.

Effects of FR and simulated M. sexta herbivory on the abundance of defense-related transcripts. (A) Schematic comparison of the effects of FR and herbivory on the abundance of photosynthesis-related transcripts (n = 25 transcripts). (B) Comparison of the effects of FR and herbivory on the abundance of transcripts involved in secondary metabolism and stress signaling (n = 120 transcripts). (C) Comparison of the effects of FR and herbivory on the expression of genes encoding enzymes of the biosynthetic pathways that lead to the formation of phenolic compounds (n = 7 transcripts for the C6–C3 group and 4 for the C15 group). The height of the box is proportional to the number of transcripts that displayed the pattern of response specified by each color combination (green, down-regulated; red, up-regulated; black, not affected). For a full list of genes, see Table 1. (D) Biosynthetic chart showing the metabolic roles of the products of genes that were significantly regulated by herbivory.
