NQR — Nicotiana attenuata

Summary

A4A49_15832 (symbol NQR) in coyote tobacco (Nicotiana attenuata) encodes a protein with NAD(P)H-dep_reductase, FMN_Rdtase-like, and Flavoprotein-like_sf domains, and is annotated with NADPH Dehydrogenase (quinone) Activity, NADH Dehydrogenase (quinone) (non-electrogenic) Activity, NAD(P)H Dehydrogenase (quinone) Activity, and FMN Binding (EC 1.6.5.2). The gene is associated with diverse biological processes including reactive oxygen species anabolism, H2O2 biosynthetic process, melatonin anabolism, Photosynthetic Electron Transport Chain, Electron Transport Chain, Wound Healing, Membrane Depolarization, Response To Yeast, and chewing. It is linked to Chloroplast Stroma, Cytosol, and plasmalemma localization. Associations with leaf dry weight, leaf necrosis, photosynthetic rate, respiration rate, and salt response have been noted. Studies of related genes in other species connect the NQR family to traits such as drought tolerance, chilling stress response, bacterial disease response, oxidative stress response, chlorophyll content, net photosynthetic rate, water use efficiency, and root branching.
