Figure 2.

Generalized pathway of secondary metabolism from chorismate to aromatic amino acids and their secondary products. Enzyme abbreviations are shown over the step(s) they catalyze; numbers next to enzyme names indicate the maximum observed fold increases in expression in WtsE-exposed versus control plants in microarray experiments. Arrow thickness relates to this fold-change value. Numbers in parentheses indicate how many genes were found up-regulated with P < 0.05. Dashed arrows indicate steps not shown. CAD, Cinnamoyl alcohol dehydrogenase; CCoAMT, caffeoyl-CoA O-methyltransferase; CcoAR, cinnamoyl-CoA reductase; CHI, chalcone isomerase; CHS, chalcone synthase; CM, chorismate mutase; COMT, caffeic acid O-methyltransferase; HCT, hydroxycinnamoyl transferase; THT, tyramine N-hydroxycinnamoyltransferase.
