DES — Cucumis melo

Summary

MELO3C018412.2 (DES, CmDES) on melon chromosome 2 encodes a cytochrome P450 enzyme with allene oxide synthase, colneleate synthase, and allene-oxide cyclase activities, along with monooxygenase and oxidoreductase functions. The gene is associated with oxylipin and jasmonic acid biosynthesis, fatty acid metabolism, sterol metabolism, and defense responses. Its product localizes to chloroplast membranes, including the thylakoid, inner membrane, and envelope, as well as the cytosol. In melon, DES is linked to photosynthetic rate and arbuscular mycorrhizal fungal colonization. Studies of related genes in other species connect the family to fruit flavor, volatile aldehyde production, and alpha-ketol formation, as well as traits including relative yield, fruit size, sugar and starch content, root volume and length, seed coat color, sporogenesis, and jasmonic acid content.
