toxic secondary metabolite biosynthetic pathway 2013-05-22T11:17:23Z PW:0001319 Those metabolic reactions involved in the synthesis of toxic secondary metabolites, known as mycotoxins, produced by some fungi, such as Fusarium. The mycotoxins they produce in cereal crops, such as species of fumonisins and trichothecenes, can affect humans and animals if present in food. mycotoxin biosynthetic pathway pathway vpetri toxic secondary metabolite metabolic pathway
