LOX — Beta vulgaris subsp. vulgaris

Summary

BvLOX (BVRB_8G196630) on sugar beet chromosome 8 encodes a lipoxygenase family protein with linoleate 13S-lipoxygenase, phytoene dehydrogenase, peroxidase, and RNA cap-binding activities. The gene is associated with jasmonic acid and oxylipin biosynthesis, lipid oxidation, green leaf volatile production, and responses to herbivores, insects, ozone, high light, and viruses. It has been linked to photoperiod-sensitive flowering time, seed yield, photosynthetic rate, root thickness, and low temperature stress response. The product localizes to chloroplast thylakoids, stromules, stress granules, and the apoplast. Studies of related genes in other species connect the family to defense against herbivory and necrotrophic pathogens, jasmonate signaling, green leaf volatile production, and resistance to potyviruses and fungal pathogens.
