NQR — Cucumis sativus

Summary

CsNQR (CSA_5G435080) on cucumber chromosome 5 encodes a protein with NAD(P)H-dependent reductase, FMN reductase-like, and flavoprotein-like superfamily domains, and is annotated with NADPH dehydrogenase (quinone) activity (EC 1.6.5.2), NADH dehydrogenase (quinone) (non-electrogenic) activity, NAD(P)H dehydrogenase (quinone) activity, and FMN binding. The gene is associated with biological processes including catabolism, regulation of autophagy, nitrate import, hormone metabolism, memory, cellular homeostasis, electron transfer, metabolic burst, autophagy, auxin anabolism, auxin transport, chlorophyll anabolism, detoxification, response to cadmium, ethylene anabolism, stomatal closure, virus-induced PTGS, and response to salt. It localizes to the chloroplast stroma, cytosol, and plasmalemma. Trait associations include plant dry weight, respiration rate, quantum yield, nitrate uptake, protein content, photosynthetic rate, chlorophyll content, and salt tolerance. Studies of related genes in other species link the family to leaf dry weight, chilling stress response, bacterial disease response, drought tolerance, water use efficiency, fruit size, sugar content, and anthocyanin content.
