NQR — Daucus carota subsp. sativus

Summary

DCAR_022340 (symbol NQR, also known as DcNQR or DcNADPH) on carrot chromosome 6 encodes a NAD(P)H-dependent reductase with FMN-binding and NAD(P)H dehydrogenase (quinone) activity (EC 1.6.5.2). The protein localises to the chloroplast stroma, cytosol and plasmalemma. In carrot, NQR is associated with the methylerythritol 4-phosphate (MEP) pathway, respiration rate and photosynthetic rate. Studies of related genes in other species link the NQR family to leaf dry weight, chilling stress response, leaf necrosis, pungency, plant dry weight, leaf water potential, leaf colour, bacterial disease response, root branching, flavonoid content, quantum yield, net photosynthetic rate, nitrate uptake, salt response, meristem identity, fruit size, water use efficiency, sugar content, protein content, stomatal resistance, anthocyanin content, root length, stomatal opening, chlorophyll content, oxidative stress response and drought tolerance.
