NQR — Cucumis sativus

Summary

CsNQR (CSA_5G623860) on cucumber chromosome 5 encodes an NAD(P)H dehydrogenase (quinone) (EC 1.6.5.2) with FMN binding, belonging to the NAD(P)H-dependent reductase and flavoprotein-like superfamily. The gene is associated with diverse biological processes including autophagy, nitrate import, auxin and ethylene metabolism, chlorophyll biosynthesis, detoxification, stomatal closure, and responses to salt and cadmium stress. It localizes to the chloroplast stroma, cytosol, and plasmalemma. Associations with agronomic traits include photosynthetic rate, chlorophyll content, quantum yield, respiration rate, nitrate uptake, protein content, plant dry weight, and salt tolerance. Related genes in other species are linked to leaf dry weight, chilling stress, bacterial disease response, drought tolerance, water use efficiency, fruit size, sugar content, and anthocyanin levels.
