AOS — Phaseolus vulgaris

Summary

PHAVU_001G017800 (PvAOS) encodes a cytochrome P450 protein with allene oxide synthase, allene-oxide cyclase, colneleate synthase, hydro-lyase, monooxygenase and oxidoreductase activities, and binds heme and iron. In French bean, this gene is associated with jasmonic acid and oxylipin biosynthesis, the epoxygenase P450 pathway, polyamine and sterol metabolism, nitrogen fixation, nodulation, and responses to wounding, jasmonic acid, fungi and peptides. It is linked to resistance to Sclerotinia sclerotiorum, salt tolerance, virus resistance, defence against necrotrophic fungi and insect herbivory, male sterility, defective anther dehiscence, sepal senescence, floral organ abscission, nectar secretion and production, somatic embryogenesis, cell death, filament elongation, sorbitol stress response, and reduced trichome density with impaired wound response. The protein localises to plastids, chloroplast membranes, thylakoids, mitochondria and the cytosol.
