ERD4 — Brassica juncea

Summary

BJUB01G02400S (ERD4, BjHYP1) on Indian mustard chromosome B01 encodes a protein with CSC1/OSCA1-like domains and mechanically gated channel activity, also annotated as calcium-activated cation channel activity. It is associated with seed germination, response to thirst, and localises to the chloroplast membrane, plasmalemma, and nucleus. The gene is linked to leaf number and drought tolerance, and to mechanosensation. Related genes in other species link the family to kinase-associated domains, though this is not established for BjHYP1 itself.
