Abstract:
Activation of Ca²⁺ signaling is a universal response to stress that allows cells to quickly respond to environmental cues. Fluctuations in cytosolic Ca²⁺ are decoded in plants by Ca²⁺-sensing proteins such as Ca²⁺-dependent protein kinases (CDPKs). The perception of microbes results in an influx of Ca²⁺ that activates numerous CDPKs responsible for propagating immune signals required for resistance against disease-causing pathogens. This review describes our current understanding of CDPK activation and regulation, and provides a comprehensive overview of CDPK-mediated immune signaling through interaction with various substrates.
