NQR — Beta vulgaris subsp. vulgaris

Summary

BvNQR (BVRB_2G041670) on sugar beet chromosome 2 encodes a protein with NAD(P)H dehydrogenase (quinone) activity, NADH dehydrogenase (quinone) (non-electrogenic) activity, and FMN binding, placing it in the NAD(P)H-dependent reductase and flavoprotein-like superfamilies. The gene is associated with response to oxidative stress, signal transduction, innate immunity, jasmonic acid and auxin anabolism, metabolic burst, homeostasis, regulation of transport, innervation, and structural organization. It localizes to the chloroplast stroma, cytosol, and plasmalemma. Associations with agronomic traits include sugar content, photosynthetic rate, respiration rate, and root length. Studies of related genes in other species link 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, and root branching.
