ERD4 — Brassica juncea

Summary

BJUB07G17380S (ERD4, BjOSCA1.6) on chromosome B07 of Indian mustard encodes a calcium-activated cation channel belonging to the CSC1/OSCA1-like family. The gene is associated with seed germination and response to thirst, and its product localises to both the chloroplast membrane and the plasmalemma. Associations with leaf number and drought tolerance have been noted. Studies of related genes in other species link the family to miscellaneous traits and climatic growth-season temperature maxima, though these functions are not established for this gene.
