ERD4 — Brassica juncea

Summary

BJUA08G28560S (ERD4, BjOSCA2.1) on Indian mustard chromosome A08 encodes a protein with CSC1/OSCA1-like domains and calcium-activated cation channel activity. The gene is associated with osmolarity sensing, seed germination, and response to thirst, and its product localizes to the chloroplast membrane, plasmalemma, and extracellular regions. It is linked to leaf number and drought tolerance. Related genes in other species are associated with root morphology traits, relative root length, and various climatic adaptation phenotypes.
