CPK16 — Solanum lycopersicum

Summary

Tomato CPK16 (also known as CPK28, CPK18, or SlCDPK16) on chromosome 3 encodes a protein with serine/threonine kinase activity, calcium ion binding, calmodulin binding, and 1-aminocyclopropane-1-carboxylate synthase activity. It contains EF-hand and protein kinase domains. This gene is associated with thermomorphogenesis, hydrogen peroxide metabolism, hormone metabolism, protein oxidation, regulation of autophagy, and water transport. It localises to the membrane, plasmalemma, cytoplasm, and nucleus. CPK16 is associated with fruit firmness, fruit weight and size, sugar content, chlorophyll content, drought tolerance, submergence tolerance, high temperature stress response, disease tolerance, flowering time, and germination ratio. It is also linked to immunity, defense response, calcium signaling, lignin deposition, ethylene biosynthesis, and salt stress tolerance.
