In nature,plant have evolved a two-layered immune system to protect themselves against diverse pathogens,including bacteria,fungi,oomycetes and so on.The first layer of the immune system is the immunity triggered upon recognition of the pathogen-associated molecular patterns(PAMPs)via cell surface-localized pattern recognition receptors(PRRs),and is called pattern-triggered immunity(PTI).The second layer of the plant immunity is triggered by activation of intracellular immune receptors,Nucleotide-binding,Leucine-rich Repeat proteins(NLR),through direct or indirect recognition of pathogen effectors,and is known as effector-triggered immunity(ETI).
