DES — Cucumis melo

Summary

MELO3C018413.2 (DES, also known as HPL) on melon chromosome 2 encodes a cytochrome P450 protein with colneleate synthase, allene oxide synthase, allene-oxide cyclase, lyase, monooxygenase and oxidoreductase activities, and binds iron and heme. The encoded protein localises to the chloroplast inner membrane, thylakoid membrane and envelope, as well as the cytosol. This gene is associated with oxylipin and jasmonic acid biosynthesis, fatty acid metabolism, sterol metabolism, cellular respiration, fruit ripening, homeostasis and defense responses. It 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, alpha-ketol formation, and traits including relative yield, fruit size, sugar content, jasmonic acid content, root volume and length, seed coat color, starch content, and net photosynthetic rate.
