Left: The putative tryptamine (red), Trp-independent (light blue), IPyA (green), indoleacetamide (yellow), and IAOx (dark blue) biosynthetic pathways to IAA in Arabidopsis. The steps shown in gray appear not to occur in peas. Right: The simplified pathway scheme suggested to occur in pea based on the present results and . N-hydroxytryptamine was not detected as a metabolite in this study, suggesting that tryptamine might be converted directly to IAAld in pea roots. The Trp-independent, indoleacetamide, and IPyA pathways were not studied.
