HPL — Solanum lycopersicum

Summary

SOLYC07G049690.3, also known as HPL or SlCYP74B2, encodes a cytochrome P450 family protein with allene oxide synthase, allene-oxide cyclase, hydro-lyase, lyase, monooxygenase, and oxidoreductase activities, and binds iron and heme. The gene is associated with the lipoxygenase pathway, oxylipin metabolism, fatty acid breakdown, and hormone metabolism, and its product localizes to chloroplast membranes. HPL is associated with fruit size, plant height, flavonoid content, pungency, and aphid response traits, as well as susceptibility to Pseudomonas syringae, C6 volatile production, hexenal signaling, and indirect defense responses. Studies of related genes in other species connect the family to green leaf volatile biosynthesis, fruit aroma, and herbivore resistance.
