DES — Cucumis sativus

Summary

CSA_7G075590 (DES, also known as HPL, AOS3, CsHPL, CsDES1, CsDES, CsAOS3) in cucumber (Cucumis sativus) on chromosome 7 encodes a cytochrome P450 family protein with allene oxide synthase, colneleate synthase, allene-oxide cyclase, lyase, monooxygenase, and oxidoreductase activities, binding heme and iron. The gene is associated with the lipoxygenase pathway, oxylipin and jasmonic acid biosynthesis, unsaturated fatty acid and lipid metabolism, and processes including fruit development, sensory perception, immune response, chlorophyll fluorescence, cellular respiration, fermentation, and chloroplast fission. It is linked to fruit flavor, fruit size, sugar content, linoleic acid content, seed coat color, photosynthetic rate, and arbuscular mycorrhizal fungal colonization. The protein localizes to the chloroplast inner membrane, thylakoid membrane, envelope, and cytosol. Studies of related genes in other species connect the family to volatile aldehyde production, alpha-ketol formation, and traits including jasmonic acid content, root length, and net photosynthetic rate.
