AOS — Brassica oleracea

Summary

BoAOS (BOLC102_C02P048650.1) on cabbage chromosome 2 encodes a cytochrome P450 enzyme with allene oxide synthase, colneleate synthase, allene-oxide cyclase, hydro-lyase, monooxygenase and oxidoreductase activities, binding heme and iron. It is associated with jasmonic acid and oxylipin biosynthesis, the epoxygenase P450 pathway, and responses to insects, fungi, and herbivory. The gene is linked to male sterility, anther dehiscence, nectar secretion, wound response, cell death, and traits including quantum yield, chlorophyll content, self-incompatibility, salt tolerance, and resistance to Sclerotinia sclerotiorum. It localises to plastids, chloroplast membranes, thylakoids, mitochondria and cytosol. Related genes in other species connect the family to jasmonic acid production, insect herbivory resistance, oxylipin biosynthesis, wound signal transduction, and tolerance to drought, heat, osmotic stress and waterlogging.
