HPL — Cucumis melo

Summary

MELO3C018833.2, symbol HPL (CmHPL), encodes a cytochrome P450 enzyme with allene oxide synthase, allene-oxide cyclase, hydro-lyase, lyase, monooxygenase and oxidoreductase activities, binding heme and iron. It localises to the chloroplast membranes. The gene is associated with oxylipin and jasmonic acid biosynthesis, fatty acid and sterol metabolism, sucrose metabolism, defense responses and wounding response. It has been linked to sugar content, C6 volatile production, hexenal signaling, volatile synthesis, arabidopside accumulation and susceptibility to Pseudomonas syringae. Studies of related genes in other species connect the family to fruit aroma, green leaf volatile biosynthesis, aphid resistance, insect resistance and herbivore defense, as well as fruit flavor, linoleic acid content, pungency, flavonoid content, fruit size and plant height.
