RD17 — Cicer arietinum

Summary

LOC101512214 (CaRD17) on chickpea chromosome 5 encodes a dehydrin family protein with a conserved dehydrin signature domain. The product is associated with actin, calcium ion, mRNA, and protein binding, and exhibits transmembrane receptor protein serine/threonine kinase activity. CaRD17 is associated with responses to desiccation, cold, heat, abscisic acid, osmotic stress, and fungal defence, as well as phloem transport, leaf vascular tissue pattern formation, and regulation of seed germination. It localises to the actin cytoskeleton, plasmodesmata, membrane, mitochondria, cytosol, plasmalemma, cytoplasm, and nucleus. The gene is associated with leaf vein morphology, and phenotypes including hyperosmotic stress response, cold acclimation, drought tolerance, and altered stress responses affecting heat, cold, osmotic, and hypoxia tolerance. Studies of related genes in other species link the dehydrin family to freezing tolerance and low-temperature responses.
