CSC1 — Brassica juncea

Summary

BjCSC1 (BJUA01G32770S) on Indian mustard chromosome A01 encodes a CSC1/OSCA1-like protein with mechanically gated channel activity and calcium-activated cation channel activity, and also shows identical protein binding. It is associated with monoatomic cation transport, seed germination, and response to thirst, and localises to the chloroplast membrane and plasmalemma. The gene is linked to leaf number and drought tolerance, as well as mechanosensation and mechanical signal transduction. Related genes in other species connect the family to hyperosmotic stress response and calcium concentration traits.
