LOX1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0573420 (HvLOX1) on chromosome 6H encodes a lipoxygenase enzyme with linoleate 13S-lipoxygenase activity (EC 1.13.11.12). The protein contains lipoxygenase and PLAT/LH2 domains and is associated with the lipoxygenase pathway, lipid oxidation, oxylipin and jasmonic acid biosynthesis, and green leaf volatile biosynthetic process. It has been connected to photoperiod-sensitive flowering time, seed yield, embryo development, root thickness, and responses to cold, wounding, herbivores, viruses, fungi, and bacteria. The gene product localises to chloroplast thylakoid membranes, stromules, P-bodies, stress granules, and the apoplast. Studies of related genes in other species link the family to jasmonate-mediated defence, green leaf volatile production, and resistance to herbivores and necrotrophic pathogens.
