LOX — Beta vulgaris subsp. vulgaris

Summary

BvLOX (BVRB_4G072060) on sugar beet chromosome 4 encodes a protein with lipoxygenase and PLAT/LH2 domains, and is annotated with linoleate 13S-lipoxygenase and phytoene dehydrogenase activities. It is associated with lipid oxidation, oxylipin and jasmonic acid biosynthesis, green leaf volatile production, and responses to herbivores, insects, viruses, ozone, and high light intensity. The gene is linked to photoperiod-sensitive flowering time, seed yield, photosynthetic rate, root thickness, and low temperature stress response. Its product localizes to chloroplast thylakoids, stromules, stress granules, and the apoplast. Studies of related genes in other species connect the family to wound response, jasmonate accumulation, drought resistance, herbivore defense, and resistance to fungal pathogens and viruses.
