CSP1 — Cicer arietinum

Summary

LOC101490833 (CaCSP1) on chickpea chromosome 6 encodes a cold shock domain-containing protein with RNA folding chaperone activity, nucleic acid binding, and DNA-binding transcription factor activity. It is associated with regulation of cellular respiration, response to desiccation and low humidity, ethylene anabolism, guard cell fate commitment, stamen and fruit development, seed development, root hair initiation, and maintenance of root meristem identity. The gene has been connected to cold tolerance, ABA accumulation, floral transition, and embryo development. Studies of related genes in other species link the family to freezing tolerance, salt stress tolerance, seed germination, ABA sensitivity, and shoot and root meristem regulation. CaCSP1 localizes to the nucleus, nucleolus, cytosol, plasmalemma, and vesicles.
