CPK16 — Cicer arietinum

Summary

LOC101502305, designated CPK16, encodes a calcium-dependent protein kinase (CDPK) in chickpea (Cicer arietinum) on chromosome 8. The product contains a Ser/Thr kinase domain, EF-hand calcium-binding motifs, and exhibits calcium-dependent protein serine/threonine kinase activity, calmodulin binding, and 1-aminocyclopropane-1-carboxylate synthase activity. CPK16 is associated with ethylene biosynthesis, response to calcium ions, inhibition of defence response to bacteria, defence response to fungi, response to heat, regulation of secondary shoot formation, and protein phosphorylation. It localises to the membrane, plasmalemma, cytoplasm, and nucleus. The gene has been linked to traits including abscisic acid concentration, ethylene sensitivity, flowering time, leaf senescence, stem elongation, high temperature stress response, disease tolerance, and salt tolerance. Related genes in other species connect the family to immune homeostasis, ethylene production, and plant growth.
