DES — Cucumis sativus

Summary

CsDES (CSA_7G075600) in cucumber encodes a fatty acid 9-hydroperoxide lyase, a cytochrome P450 family protein with allene oxide synthase, colneleate synthase, allene-oxide cyclase, lyase, monooxygenase, and oxidoreductase activities, and binds heme and iron. It is associated with the lipoxygenase pathway, oxylipin and jasmonic acid biosynthesis, fatty acid metabolism, immune and defense responses, fruit development and ripening, and sterol metabolism. The gene is linked to linoleic acid content and photosynthetic rate, and has been connected to arbuscular mycorrhizal fungal colonization. Its product localizes to the chloroplast membrane, inner membrane, thylakoid membrane, envelope, and cytosol. Studies of related genes in other species link the family to relative yield, fruit flavor, root volume, seed coat color, net photosynthetic rate, starch and sugar content, fruit size, jasmonic acid content, root length, photochemical quenching, and volatile aldehyde production.
