NQR — Lactuca sativa

Summary

LsNQR (NQR) on chromosome 4 of garden lettuce encodes a protein with NADPH dehydrogenase (quinone) and NADH dehydrogenase (quinone) activities, binding FMN and belonging to the FMN_Rdtase-like and flavoprotein-like superfamilies. This gene is associated with hydrogen peroxide biosynthetic process, metabolic burst, and seed germination, and its product localises to the chloroplast stroma, cytosol, and plasmalemma. LsNQR is linked to respiration rate and photosynthetic rate. Studies of related genes in other species connect the NQR family to a wide range of traits including leaf dry weight, chilling stress response, bacterial disease response, drought tolerance, salt response, oxidative stress response, net photosynthetic rate, water use efficiency, chlorophyll content, anthocyanin content, flavonoid content, sugar content, protein content, fruit size, root branching, root length, meristem identity, stomatal resistance, stomatal opening, leaf water potential, leaf color, leaf necrosis, pungency, nitrate uptake, and quantum yield.
