Figure 1From: Early activation of wheat polyamine biosynthesis during Fusarium head blight implicates putrescine as an inducer of trichothecene mycotoxin productionPrinciple pathway of polyamine biosynthesis in plants. Expression of all genes encoding enzymes of the pathway were investigated except for agmatine deaminase, carbamoylputrescine amidase and spermine synthase. Metabolites measured in this study included arginine, putrescine, spermine and spermidine. Metabolites indicated by an asterisk were previously shown to have in vitro trichothecene inducing activity [18].Back to article page
