HPL — Medicago truncatula

Summary

MTR_2G087890, designated MtHPL1 (also known as HPL, CYP74B2), 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. The gene is associated with oxylipin and jasmonic acid biosynthesis, fatty acid metabolism, defense response, and response to wounding. Its product localizes to chloroplast membranes, including the outer and inner membranes, thylakoid membrane, and envelope, as well as the cytosol. MtHPL1 is associated with susceptibility to Pseudomonas syringae, C6 volatile production, hexenal signaling, and arabidopside accumulation. Studies of related genes in other species connect the family to root morphology traits.
