NQR — Solanum lycopersicum

Summary

SlNQR (SOLYC01G096420.3) on tomato chromosome 1 encodes a flavoprotein with FMN-binding and NAD(P)H dehydrogenase (quinone) activity, belonging to the FMN_reductase-like family. The gene is associated with diverse biological processes including reactive oxygen species and hydrogen peroxide biosynthesis, the ascorbate-glutathione cycle, cellular respiration, nitrate import, and protein oxidation. It localises to the chloroplast stroma, cytosol and plasma membrane. SlNQR has been linked to several agronomically important traits: leaf necrosis and colour, chlorophyll and anthocyanin content, fruit size, net photosynthetic rate, quantum yield, water use efficiency, stomatal resistance and opening, drought tolerance, and bacterial disease response. Studies of related genes in other species connect the family to salt and oxidative stress responses, chilling tolerance, root branching, and flavonoid and sugar content.
