plants express cell membrane-localized pattern recognition receptors (PRRs) and intracellular nucleotide-binding leucine-rich repeat (NLR) receptors to fend off pathogens. PRR recognition of conserved microbial features and NLR recognition of pathogen effectors lead to pattern-triggered immunity (PTI) and effectortriggered immunity (ETI), respectively [1].
