NQR — Beta vulgaris subsp. vulgaris

Summary

BvNQR (BVRB_2G041660) on sugar beet chromosome 2 encodes a protein with NAD(P)H-dependent reductase, FMN reductase-like and flavoprotein-like domains, and exhibits NADPH dehydrogenase (quinone) and NADH dehydrogenase (quinone) activities with FMN binding. The gene is associated with response to oxidative stress, signal transduction, innate immunity, metabolic burst, jasmonic acid and auxin anabolism, homeostasis, regulation of transport, innervation, and structural organization. Its product localizes to the chloroplast stroma, cytosol, and plasmalemma. BvNQR is linked to sugar content, photosynthetic rate, respiration rate, root length, and oxidative stress response. Studies of related genes in other species connect the family to leaf dry weight, chilling stress response, drought tolerance, salt response, bacterial disease response, net photosynthetic rate, water use efficiency, chlorophyll content, anthocyanin content, flavonoid content, root branching, fruit size, and meristem identity.
