ERD4 — Brassica juncea

Summary

BJUB08G31710S (symbol ERD4, preferred name BjOSCA1.1) on Indian mustard chromosome B08 encodes a protein with CSC1/OSCA1-like and Malonyl-CoA decarboxylase-like domains. The gene is associated with calcium-activated and monoatomic cation channel activity, and has been linked to cellular hyperosmotic response, regulation of calcium ion import, protein tetramerization, seed germination, osmotic response, and response to thirst. The encoded product localises to the chloroplast membrane, cytosol, and plasmalemma. BjOSCA1.1 is associated with leaf number and drought tolerance. Studies of related genes in other species link the family to mechanosensitivity.
