Response of the Arabidopsis indolic secondary metabolite network to infection with Colletotrichum higginsianum (opens in new tab)

In plants, the indolic amino acid tryptophan (Trp) serves as the precursor for the synthesis of a plethora of indolic secondary metabolites with allelopathic activity against microbes or toxicity against herbivores. In the cruciferous model plant Aradidopsis, indolic glucosinolates, the major phytoalexin camalexin, carbonyl nitriles and indole carboxylic acids are abundant products of the branched biosynthetic pathway that originates from the Trp oxidation product indole-acetaldoxime (IAOx). ...
