ERD4 — Brassica juncea

Summary

BJUA03G32700S (symbol ERD4, preferred name BjOSCA1.1) on Indian mustard chromosome A03 encodes a calcium-activated cation channel, belonging to the CSC1/OSCA1-like family with Malonyl-CoA decarboxylase-related domains. The gene is associated with calcium ion import regulation, protein tetramerization, and cellular responses to osmotic stress and thirst. It has been linked to seed germination, leaf number, and drought tolerance. The product localises to the chloroplast membrane, cytosol, and plasmalemma. Related genes in other species connect the family to mechanosensitivity.
