Figure 2. Indole-3-acetic acid (IAA) biosynthetic pathways starting from L-tryptophan.
Top: aldoxime pathway; middle: indole-3-acetamide pathway; bottom: indole pyruvate pathway (IpyA). Locus tags are indicated for genes that could be identified. Dashed, crossed-out lines represent pathways that are absent in P. vagans C9-1.
