Pattern-recognition receptors are required for NLR-mediated plant immunity.

ABSTRACT: The plant immune system is fundamental for plant survival in natural ecosystems and for productivity in crop fields. Substantial evidence supports the prevailing notion that plants possess a two-tiered innate immune system, called pattern-triggered immunity (PTI) and effector-triggered immunity (ETI). PTI is triggered by microbial patterns via cell surface-localized pattern-recognition receptors (PRRs), whereas ETI is activated by pathogen effector proteins via predominantly intracellularly localized receptors called nucleotide-binding, leucine-rich repeat receptors (NLRs)^1-4. PTI and ETI are initiated by distinct activation mechanisms and involve different early signalling cascades^5,6. Here we show that Arabidopsis PRR and PRR co-receptor mutants-fls2 efr cerk1 and b
