Plants lack the mechanisms needed for adaptive immunity and thus rely entirely on innate immunity to protect themselves from pathogens and pests [1]. Their innate immune systems must protect against innumerable, highly adaptable viruses bacteria, fungi, oomycetes, nematodes, and insects. Two important components of the plant immune system are induced by the presence of pathogen molecules [1]. O...

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...
