AOS — Cucumis sativus

Summary

CSA_2G360780 (symbol AOS) on cucumber chromosome 2 encodes an allene oxide synthase, a cytochrome P450 enzyme with allene oxide synthase, colneleate synthase, allene-oxide cyclase, hydro-lyase, monooxygenase, and oxidoreductase activities, and binds heme and iron. The gene is associated with jasmonic acid anabolism, oxylipin metabolism, unsaturated fatty acid metabolism, the epoxygenase P450 pathway, induced systemic resistance, systemic acquired resistance, secondary metabolism, chlorophyll fluorescence, cell wall organization, and cellular respiration. Its product localizes to the chloroplast membrane, thylakoid, envelope, plastid, mitochondria, and cytosol. AOS is linked to photosynthetic rate, plant height, root length, salt tolerance, resistance to Sclerotinia sclerotiorum, virus resistance, nectar secretion, male sterility, defense responses to insect herbivory and necrotrophic fungi, and somatic embryogenesis. Related genes in other species are linked to wound response, herbivore-induced volatile emission, and parasitoid attraction.
