MDAR5 — Medicago truncatula

Summary

MTR_8G098910 (symbol MDAR5, also known as MtMDAR6) on barrel medic chromosome 8 encodes a protein with monodehydroascorbate reductase activity, leghemoglobin reductase activity, and dihydrolipoyl dehydrogenase (NADH) activity, belonging to the FAD/NAD-binding domain family. The gene is associated with nitrogen fixation, nodulation, phytochelatin anabolism, flavonoid metabolism, 2-oxoglutarate metabolism, fermentation, cellular oxidant detoxification, and responses to salt, cold, and salinity. It is linked to chlorophyll content and chlorophyll fluorescence, as well as signal transduction and homeostasis. The product localizes to mitochondria, chloroplast stroma, peroxisome membrane, cytoplasm, and nucleus. Studies of related genes in other species, such as monodehydroascorbate reductase (NADH) and EC 1.6.5.4, connect the family to similar oxidoreductase functions.
