LOX — Solanum tuberosum

Summary

PGSC0003DMG400007793 (LOX, also known as Lox2, LOX6, StLOX3.1, and several other synonyms) on potato chromosome 12 encodes a lipoxygenase, a member of the lipoxygenase protein family characterized by conserved domains including LipOase_CS, LipOase_Fe_BS, and LipOase_plant. The enzyme exhibits linoleate 13S-lipoxygenase activity, oxidoreductase activity, and has been annotated with phytoene dehydrogenase, peroxidase, and salicylic acid binding activities. LOX is associated with the lipoxygenase pathway, oxylipin and jasmonic acid biosynthesis, lipid oxidation, wound healing, response to herbivores, and regulation of secondary metabolism. It localizes to chloroplast thylakoids, stromules, stress granules, and the apoplast. The gene is linked to traits including photoperiod-sensitive flowering time, seed yield, photosynthetic rate, salt and low temperature stress responses, root thickness, and jasmonic acid content. Studies of related genes in other species connect the family to jasmonate biosynthesis, wound response, resistance to herbivory and necrotrophic pathogens, and stomatal closure.
