ERD4 — Brassica juncea

Summary

BJUB03G30310S (ERD4, BjOSCA1.8) on Indian mustard chromosome B03 encodes a CSC1/OSCA1-like protein with mechanically gated channel activity and calcium-activated cation channel activity. The gene is associated with seed germination and response to thirst, and its product localises to the chloroplast membrane, plasmodesma, Golgi complex and plasmalemma. It is associated with leaf number and drought tolerance. Studies of related genes in other species link the family to yield and root morphology traits, as well as seed and root phenotypes.
