NQR — Solanum tuberosum

Summary

StNQR (PGSC0003DMG400005410) on potato chromosome 1 encodes a NAD(P)H dehydrogenase (quinone) (EC 1.6.5.2) with FMN binding, belonging to the NAD(P)H-dependent reductase and flavoprotein-like superfamilies. The gene is associated with oxidative phosphorylation, cellular respiration, electron transport, and the MAPK cascade, as well as wound healing, immune response, cell death, jasmonic acid signaling, and regulation of reactive oxygen species. It is linked to starch breakdown, pH reduction, and homeostasis, and localises to the chloroplast stroma, cytosol, and plasmalemma. Associations with respiration rate, photosynthetic rate, and meristem identity have been noted. Studies of related genes in other species connect the family to traits including drought tolerance, salt response, chilling stress response, bacterial disease response, leaf dry weight, chlorophyll content, net photosynthetic rate, water use efficiency, and anthocyanin content.
