The intracellular nucleotide-binding domain leucine-rich repeat (NLR) class of immune receptors plays an important role in plant viral defence. Plant NLRs recognize viruses through direct or indirect association of viral proteins, triggering a downstream defence response to prevent viral proliferation and movement within the plant. This review focuses on current knowledge of intracellular perception of viral pathogens, activation of NLRs and the downstream signalling components involved in plant viral defence.
Keywords: Effector-triggered immunity (ETI); Immune receptors; NLR activation; immune signalling; nucleotide-binding domain leucine-rich repeat receptors (NLRs); plant viruses; viral effectors.
