NQR — Solanum tuberosum

Summary

StNQR (PGSC0003DMG400005404) on potato chromosome 1 encodes an NAD(P)H:quinone oxidoreductase (EC 1.6.5.2) with NADPH dehydrogenase (quinone) activity, NADH dehydrogenase (quinone) (non-electrogenic) activity, and FMN binding. This flavoprotein contains an NAD(P)H-dependent reductase domain and is associated with oxidative phosphorylation, the electron transport chain, cellular respiration, and ROS metabolic processes. It is linked to wound healing, immune response, MAPK cascade, jasmonic acid signaling, salt response, and pH reduction. The gene is associated with respiration rate, photosynthetic rate, and meristem identity. The product localizes to the chloroplast stroma, cytosol, and plasmalemma. Studies of related genes in other species link the family to traits including leaf dry weight, chilling stress response, bacterial disease response, drought tolerance, water use efficiency, and anthocyanin content.
