LOX1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0679840 (HvLOX1) on barley chromosome 7H encodes a lipoxygenase enzyme with linoleate 13S-lipoxygenase and oxidoreductase activities, containing Lipoxygenase and PLAT/LH2 domains. It is associated with the lipoxygenase pathway, lipid oxidation, oxylipin and jasmonic acid biosynthesis, green leaf volatile biosynthetic process, and responses to wounding, herbivore, virus, fungi, bacteria, cold, and salicylic and jasmonic acids. The gene is linked to photoperiod-sensitive flowering time, seed yield, plant embryo development, low temperature stress response, root thickness, nitrogen use efficiency, insect herbivory resistance, and plant yield. The product localizes to chloroplast thylakoids, stromules, the apoplast, and stress granules. Studies of related genes in other species connect the family to insect resistance, green leaf volatile biosynthesis, and defense against fungal pathogens and herbivory.
