Arabidopsis Calcium Dependent Protein Kinase 3, and Its Orthologues OsCPK1, OsCPK15, and AcCPK16, Are Involved in Biotic and Abiotic Stresses.

ABSTRACT: Calcium-dependent protein kinases (CPKs) are plant proteins that directly bind calcium ions before phosphorylating substrates involved in biotic and abiotic stress responses, as well as development. Arabidopsis thaliana CPK3 (AtCPK3) is involved with plant signaling pathways such as stomatal movement regulation, salt stress response, apoptosis, seed germination and pathogen defense. In this study, AtCPK3 and its orthologues in relatively distant plant species such as rice (Oryza sativa, monocot) and kiwifruit (Actinidia chinensis, asterid eudicot) were analyzed in response to drought, bacteria, fungi, and virus infections. Two orthologues were studied in O. sativa, namely OsCPK1 and OsCPK15, while one orthologue-AcCPK16-was ide
