Plants possess two distinct types of immune receptor. The first type, pattern recognition receptors (PRRs), recognizes microbe-associated molecular patterns (MAMPs) and initiates pattern-triggered immunity (PTI) on recognition. FLS2 is a PRR, which recognizes a part of bacterial flagellin. The second type, resistance (R) proteins, recognizes pathogen effectors and initiates effector-triggered immunity (ETI) on recognition. RPM1, RPS2 and RPS5 are R proteins. Here, we provide evidence that FLS2 is physically associated with all three R proteins. Our findings suggest that signalling interactions occur between PTI and ETI at very early stages and/or that FLS2 forms a PTI signalling complex, some components of which are guarded by R proteins.
