AFRR — Solanum tuberosum

Summary

StAFRR (PGSC0003DMG400002703) on potato chromosome 9 encodes a monodehydroascorbate reductase with dihydrolipoyl dehydrogenase (NADH) activity, belonging to the FAD/NAD-binding oxidoreductase family. The gene is associated with cellular oxidant detoxification, stress and immune responses, salinity response, and regulation of metabolism, including 2-oxoglutarate and glycine cleavage system processes. It is linked to mitochondrial and peroxisomal localisation, particularly the glycine cleavage system and KGDHC. Trait associations include water use efficiency, photosynthetic rate, root length and thickness, and drought tolerance. Studies of related genes in other species connect the family to net photosynthetic rate, leaf water potential, root volume, plant height, and fruit size.
