CIPK5 — Cicer arietinum

Summary

LOC101510050, designated CaCIPK5 or CIPK5, encodes a serine/threonine protein kinase containing a NAF/FISL domain and is annotated with calcium-dependent protein serine/threonine phosphatase activity, protein serine kinase activity, calcium ion binding, and ATP binding. This chickpea gene on chromosome 4 is associated with the downregulation of seed dormancy, release of seed from dormancy, upregulation of seed germination, and upregulation of gibberellic acid mediated signaling. It is linked to potassium ion homeostasis and transport, hypotonic and hyperosmotic salinity responses, cellular salinity response, regulation of stomatal closure, and response to hypoxia. Associations include traits such as water stress response, leaf chlorosis, transpiration rate, root length, root hair length, days to flowering, floral organ development, and seedling growth. The gene product localizes to the tonoplast, vacuole, membrane, pollen tube, and calcineurin complex. Studies of related genes in other species link the CIPK family to salinity tolerance, hypoxia tolerance, potassium acquisition, and pollen tube growth.
