Involved in the biosynthesis of homoterpenes, attractants of herbivores parasitoids and predators (e.g. predatory mites and parasitoid wasps) (By similarity). Component of the volatile terpenes biosynthesis pathways (PubMed:30187155). Converts mainly nerolidol to dimethylnonatriene (DMNT) and, to a lower extent, geranyllinalool to trimethyltridecatetraene (TMTT) (PubMed:27662898). (6E,10E)-geranyllinalool + O2 + reduced [NADPH--hemoprotein reductase] = (3E,7E)-4,8,12-trimethyltrideca 1,3,7,11-tetraene + but-3-en-2-one + H(+) + 2 H2O + oxidized [NADPH--hemoprotein reductase] (3S,6E)-nerolidol + O2 + reduced [NADPH--hemoprotein reductase] = (3E)-4,8-dimethylnona-1,3,7-triene + but-3-en-2-one + H(+) + 2 H2O + oxidized [NADPH--hemoprotein reductase] Secondary metabolite biosynthesis; terpenoid biosynthesis. Strongly induced in response to herbivory-mediated wounding. Impaired biosynthesis of dimethylnonatriene (DMNT), but abnormal accumulation of (E)-nerolidol (PubMed:27662898). Reduced levels of trimethyltridecatetraene (TMTT) (PubMed:27662898). Belongs to the cytochrome P450 family.
