BIP — Cicer arietinum

Summary

CaBIP (LOC101513614) on chickpea chromosome 6 encodes a member of the Hsp70 family, specifically a luminal-binding protein (BIP) with a heat shock protein 70 chaperone domain and ATPase activity. The gene is associated with the unfolded protein response, ER stress response, and protein folding in the ER, as well as cellular response to cold and downregulation of ethylene-mediated signaling. It has been connected to numerous traits including temperature stress response, osmotic response sensitivity, root hair length, stomatal resistance, auxin sensitivity, flowering time, disease tolerance, and seed growth and development. The gene is also linked to virus resistance, cold tolerance, thermotolerance, male fertility, and root hair elongation. Studies of related genes in other species link the family to cadmium stress tolerance and seed germination.
