LOX — Beta vulgaris subsp. vulgaris

Summary

BvLOX (BVRB_4G072090) on sugar beet chromosome 4 encodes a protein with lipoxygenase domains and linoleate 13S-lipoxygenase activity, also annotated with phytoene dehydrogenase, peroxidase, and salicylic acid binding activities. The protein localizes to chloroplast thylakoids, stromules, and stress granules. BvLOX is associated with jasmonic acid and oxylipin biosynthesis, lipid oxidation, green leaf volatile production, and responses to herbivores, insects, high light, ozone, and viruses. It is linked to photoperiod-sensitive flowering, seed yield, photosynthetic rate, root thickness, and low temperature stress response. Related genes in other species are associated with jasmonate-mediated defense, wound response, resistance to herbivory and necrotrophic pathogens, leaf senescence, and stomatal closure.
