AOS — triticum aestivum

Summary

TRAESCS5D02G413200 (TaAOS) on wheat chromosome 5D encodes a cytochrome P450 enzyme with allene oxide synthase, colneleate synthase, allene-oxide cyclase and hydro-lyase activities, and is also annotated for monooxygenase and oxidoreductase functions. The gene is associated with oxylipin, fatty acid, sterol and methionine metabolism, the lipoxygenase and epoxygenase P450 pathways, and stress-activated MAPK cascades. It is linked to defense responses including callose deposition, systemic acquired resistance, innate immune response, and detection of biotic stimulus, as well as regulation of hydrogen peroxide metabolism and apoptotic processes. Associations with agronomic traits include grain weight, plant height, anthesis time, leaf lamina length, photosynthetic rate, cold tolerance, and resistance to stem rust, stripe rust and salt stress. The protein localizes to chloroplast membranes, thylakoids, plastids and mitochondria.
