NQR — Beta vulgaris subsp. vulgaris

Summary

BvNQR (BVRB_2G041680) on sugar beet chromosome 2 encodes a protein with NADPH dehydrogenase (quinone) activity, NADH dehydrogenase (quinone) (non-electrogenic) activity, and FMN binding, belonging to the NAD(P)H-dependent reductase, FMN reductase-like, and flavoprotein-like superfamilies. The gene is associated with response to oxidative stress, signal transduction, innate immunity, metabolic burst, jasmonic acid anabolism, auxin anabolism, regulation of transport, homeostasis, innervation, and structural organization. Its product localises to the chloroplast stroma, cytosol, and plasmalemma. BvNQR is linked to respiration rate, sugar content, photosynthetic rate, root length, and oxidative stress response. Studies of related genes in other species connect the family to drought tolerance, salt response, chilling stress response, bacterial disease response, leaf dry weight, water use efficiency, chlorophyll content, anthocyanin content, and fruit size.
