ERD4 — Brassica juncea

Summary

BJUA06G33570S (symbol ERD4, preferred name BjOSCA1.3) on Indian mustard (Brassica juncea) chromosome A06 encodes a protein belonging to the CSC1/OSCA1-like family. The gene product is annotated with calcium-activated cation channel activity, calcium channel activity, and protein binding, and is localized to the chloroplast membrane, plasmalemma, and extracellular space. BjOSCA1.3 is associated with PTI signalling, stomatal movement, seed germination, and response to thirst. It has been linked to leaf number, drought tolerance, and stomatal immunity. Related genes in other species connect the ERD (early-responsive to dehydration stress) family to dehydration responses.
