NQR — Nicotiana attenuata

Summary

A4A49_15833 (symbol NQR) in coyote tobacco (Nicotiana attenuata) encodes a protein with NAD(P)H-dependent reductase and flavoprotein-like superfamily domains, and is annotated with NADPH dehydrogenase (quinone) activity (EC 1.6.5.2), NADH dehydrogenase (quinone) (non-electrogenic) activity, NAD(P)H dehydrogenase (quinone) activity, and FMN binding. The gene is associated with diverse biological processes including reactive oxygen species anabolism, H2O2 biosynthetic process, photosynthetic electron transport chain, electron transport chain, wound healing, response to yeast, membrane depolarization, G1 phase, S phase, anaphase, and melatonin anabolism. It is linked to chloroplast stroma, cytosol, and plasmalemma localization. Associations with traits include leaf dry weight, leaf necrosis, photosynthetic rate, respiration rate, and salt response. Studies of related genes in other species link the NQR family to traits such as drought tolerance, chilling stress response, bacterial disease response, chlorophyll content, net photosynthetic rate, water use efficiency, and flavonoid and anthocyanin content.
