ERD4 — Brassica juncea

Summary

BJUB08G30520S (symbol ERD4, preferred name BjOSCA1.7) on Indian mustard chromosome B08 encodes a calcium-activated cation channel, belonging to the CSC1/OSCA1-like family with cytosolic, N-terminal and seven-transmembrane domains. The gene is associated with seed germination, response to thirst, and localisation to the chloroplast membrane, extracellular region and plasmalemma. It has been linked to leaf number and drought tolerance. Studies of related genes in other species connect the OSCA1.7 family to metabolite content and iron concentration traits.
