HPL — Asparagus officinalis

Summary

A4U43_C01F13220 (AoHPL) encodes a cytochrome P450 family protein with colneleate synthase, allene oxide synthase, allene-oxide cyclase, lyase, monooxygenase and oxidoreductase activities, and binds iron and heme. It is associated with the lipoxygenase pathway, oxylipin and jasmonic acid anabolism, ether anabolism, sterol metabolism, fatty acid metabolism and anabolism, defense response and response to wounding. The product localises to the chloroplast outer membrane, chloroplast membrane, chloroplast inner membrane, chloroplast thylakoid membrane, chloroplast envelope and cytosol. AoHPL is linked to C6 volatile production, hexenal signaling, 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 and insect defense.
