LOX3 — Phaseolus vulgaris

Summary

PHAVU_009G262900, designated PvLOX3, encodes a lipoxygenase enzyme with linoleate 9S- and 13S-lipoxygenase activity, peroxidase activity, and salicylic acid binding, and contains lipoxygenase and PLAT/LH2 domains. In French bean, this gene is associated with jasmonic acid and oxylipin biosynthesis, green leaf volatile production, lipid oxidation, anther development and dehiscence, filament development, and responses to high light, ozone, insects, fungi, bacteria, and salicylate. The protein localizes to chloroplast thylakoids, stromules, envelope, stroma, apoplast, and cytosol. PvLOX3 is linked to male fertility, plant growth, lateral root and inflorescence development, and tolerance to cadmium, heat, salt, drought, and copper stress, as well as resistance and susceptibility to root-knot nematode infection. Studies of related genes in other species connect the family to N-acylethanolamine metabolism.
