ERD4 — Brassica juncea

Summary

BJUA08G10020S (symbol ERD4, preferred name BjOSCA1.6) encodes a calcium-activated cation channel protein belonging to the CSC1/OSCA1-like family, with domains including the cytosolic, N-terminal and seven-transmembrane regions. The gene is associated with seed germination and response to thirst, and its product localises to the chloroplast membrane and plasmalemma. BjOSCA1.6 is associated with leaf number and drought tolerance. Studies of related genes in other species connect the family to miscellaneous traits and climatic growth-season temperature maxima, though these associations are not yet established in B. juncea.
