LOX — Beta vulgaris subsp. vulgaris

Summary

BVRB_7G169930 (BvLOX) encodes a lipoxygenase enzyme with linoleate 9S- and 13S-lipoxygenase activity, as well as phytoene dehydrogenase, peroxidase, and salicylic acid-binding activities. The protein contains lipoxygenase and PLAT/LH2 domains and localizes to chloroplast thylakoids, stromules, and stress granules. BvLOX is associated with jasmonic acid and oxylipin biosynthesis, green leaf volatile production, and responses to herbivores, insects, ozone, high light, 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 have been connected to wound response, drought resistance, cadmium stress tolerance, and defense against herbivory. BvLOX is also associated with anther development, anther dehiscence, and cell redox homeostasis.
