One of the main Ca2+ decoders in plants are calcium-dependent protein kinases (CDPKs). Among them, AtCPK1 is one of the best studied as a positive regulator in the plant response to biotic and abiotic stress. Inactivation of the autoinhibitory domain of AtCPK1 (the mutated form of AtCPK1-Ca) provides constitutive activity of the kinase via imitation of the stress-induced Ca2+ increase. For the first time in the present study, we performed a proteomic analysis of the overexpressed mutant AtCPK1-Ca form of Arabidopsis thaliana in transformed Vitis amurensis calli. In our previous studies, we have shown that overexpression of this mutated form led to dramatically enhanced specialised metabolism in plant cell cultures, including resveratrol in V. amurensis.
