Summary The bacterial flagellin (FliC) epitopes flg22 and flg II ‐28 are microbe‐associated molecular patterns ( MAMP s). Although is recognized by many plant species via the pattern recognition receptor FLS 2, neither nor extent of different families known. Here, we tested significance as a importance allelic diversity in plant–pathogen interactions using purified peptides Pseudomonas syringae ∆ fliC mutant complemented with alleles. genotype were found to significantly affect immune response, but not motility. restricted number solanaceous species. peptide does trigger any response Arabidopsis, mutations both have 2 ‐dependent effects on virulence. However, expression tomato allele confer Nicotiana benthamiana ability detect ‐28, plants silenced for altered recognition. Therefore, diversification an effective pathogen virulence strategy, appears be perceived yet unidentified Solanaceae, although it has effect Arabidopsis.
