Abstract

The Arabidopsis RRS1-R/RPS4 immune receptor complex responds to bacterial effectors AvrRps4 and PopP2. Guo et al. show that effector-enhanced RRS1 N- and C-terminal proximity comprises a critical reconfiguration step involved in derepression of the complex. Further, RRS1-R C-terminal phosphorylation-dependent conformational reconfigurations distinguish responsiveness to the two effectors.
