Plants possess innate immune systems to prevent most potential infections. The ancient and conserved innate immune responses are triggered by microbe‐associated molecular patterns (MAMPs) and play important roles in broad‐spectrum defenses. However, successful bacterial pathogens evolved type III virulence effectors to suppress MAMP‐mediated immunity. To survive, plants further developed highly specific resistance ( R ) genes to trigger gene‐for‐gene‐mediated immunity and turn the virulent pathogens into avirulent ones. We summarize here the very recent advances in this dynamic coevolution of plant‐bacterium interaction.
