AFRR — Capsicum annuum

Summary

CaAFRR (T459_22355) on pepper chromosome 9 encodes a monodehydroascorbate reductase (NADH) with dihydrolipoyl dehydrogenase (NADH) activity, an oxidoreductase acting on NAD(P)H that binds FAD or FADH2 and nucleotides. The gene is associated with the ascorbate-glutathione cycle, 2-oxoglutarate metabolism, glycine decarboxylation, cellular respiration, protein oxidation, detoxification, response to hypoxia, chlorophyll fluorescence, fruit ripening, and signal transduction. It localises to mitochondria, peroxisome membrane, and the glycine cleavage system. CaAFRR is associated with net photosynthetic rate, fruit size, plant height, stem diameter, root volume and length, leaf water potential, and pungency. Studies of related genes in other species connect the family to drought tolerance and water use efficiency.
