Assembling the biosynthetic puzzle of crucifer metabolites: indole-3-acetaldoxime is incorporated efficiently into phytoalexins but glucobrassicin isnot

First biosynthetic studies utilizing tetradeuterated precursors indicate th at the indole glucosinolate glucobrassicin is not a precursor of the phytoa lexin brassinin, and that indole-3-acetaldoxime is an efficient precursor.
