NQR — Cucumis melo

Summary

MELO3C005147.2 (symbol NQR, preferred name CmNQR) on melon chromosome 10 encodes a NAD(P)H dehydrogenase (quinone) enzyme (EC 1.6.5.2) with NADPH and NADH dehydrogenase (quinone) activities, binding FMN and belonging to the NAD(P)H-dependent reductase and flavoprotein-like superfamilies. The gene is associated with fruit development, metabolic burst, and homeostasis, and its product localizes to the chloroplast stroma, cytosol, and plasmalemma. It is associated with respiration rate, photosynthetic rate, and flavonoid content. Studies of related genes in other species connect the family to traits including chilling stress response, bacterial disease response, drought tolerance, salt response, oxidative stress response, leaf dry weight, net photosynthetic rate, chlorophyll content, anthocyanin content, sugar content, fruit size, water use efficiency, and stomatal resistance.
