SO — Brassica juncea

Summary

BJUA06G32230S (BjSO) on Indian mustard chromosome A06 encodes a molybdenum cofactor-binding oxidoreductase with sulfite oxidase, nitrate reductase, and cytochrome-b5 reductase activities, and contains FAD, heme, and molybdenum ion binding sites. The gene is associated with nitrate assimilation, sulfur metabolism, chlorophyll metabolism, nitric oxide anabolism, and responses to sulfur dioxide, nitrite, and light stimulus. It is linked to leaf shaping, regulation of lateral root development, and root development, and localizes to mitochondria, cytosol, and organelle membranes. Associations also include virus resistance. Studies of related genes in other species connect the family to sulfite oxidation, sulfite detoxification, selenite oxidation, and leaf necrosis.
