AOS — Brassica oleracea var. botrytis

Summary

BoAOS (BOLND125_C02P054590.1_BOLND125_V1) on cauliflower chromosome 2 encodes a cytochrome P450 family protein 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 anabolism, oxylipin metabolism, fatty acid metabolism, and defence responses to wounding, fungi, and herbivory. The gene is linked to male sterility, anther dehiscence, nectar secretion, salt tolerance, somatic embryogenesis, and resistance to Sclerotinia sclerotiorum. It localises to chloroplast membranes, thylakoids, plastids, mitochondria and the cytosol. Studies of related genes in other species connect the family to additional traits including drought tolerance, heat stress tolerance, aphid resistance, seed weight, chlorophyll content, and potassium uptake.
