Plants and animals sense intruding pathogens by using proteins that recognize diverse microbe-associated molecular patterns (MAMPs) and initiate innate immune responses. Early signalling responses in the host include calcium influx, an oxidative burst and transcriptional reprogramming. Here, four calcium-dependent protein kinases are described that function as calcium sensors, act as convergence points for various MAMPs, and are crucial for transcriptional reprogramming and oxidative burst in plants.
