MDAR1 — Brachypodium distachyon
Summary
Brachypodium distachyon gene MDAR1 (BRADI_4G38430V3) encodes a monodehydroascorbate reductase (MDHAR) with FAD/NAD-binding domains and leghemoglobin reductase activity. This enzyme is associated with cellular oxidant detoxification, hydrogen peroxide catabolism, and response to jasmonic acid. It has been linked to lignin content, photosynthetic rate, and disease tolerance. The gene product localizes to multiple cellular compartments including the peroxisomal lumen, chloroplast envelope, plasmodesmata, and apoplast. MDAR1 is associated with shoot development, carbohydrate and secondary metabolism, and responses to zinc, symbiotic fungi, and viruses. Studies of related genes in other species link the family to salt and drought stress tolerance, antioxidative responses, seedling growth, and mutualistic interactions with Piriformospora indica.
