ERD4 — Brassica juncea

Summary

BJUA01G25310S (symbol ERD4, preferred name BjOSCA1.6) on Indian mustard chromosome A01 encodes a protein with calcium-activated cation channel activity, belonging to the CSC1/OSCA1-like family with cytosolic, N-terminal and seven-transmembrane domains. The gene is associated with seed germination and response to thirst, and its product localises to the chloroplast membrane and plasmalemma. Associations include leaf number and drought tolerance. Studies of related genes in other species link the OSCA1.6 family to miscellaneous traits and climatic growth-season temperature maxima, though these findings are not established for this gene.
