SO — Brassica juncea

Summary

BjSO (BJUB06G22590S) from Indian mustard (Brassica juncea) chromosome B06 encodes a molybdenum cofactor-binding oxidoreductase with nitrate reductase, sulfite oxidase, and cytochrome-b5 reductase activities, along with FAD, heme, and molybdenum ion binding. The gene is associated with nitrate assimilation, sulfur metabolism, chlorophyll metabolism, nitric oxide anabolism, and responses to sulfur dioxide, nitrite, and light stimulus. It has been linked to leaf shaping, lateral root development, and root development, and localises to mitochondria, cytosol, and organelle membranes. Associations with virus resistance have also been noted. Studies of related genes in other species connect the family to sulfite oxidation, sulfite detoxification, and selenite oxidation, and to leaf necrosis.
