Abstract
Direct or indirect recognition of pathogen-derived effectors by plant nucleotide-binding leucine-rich repeat (LRR) receptors (NLRs) initiates innate immune responses. The Hyaloperonospora arabidopsidis effector ATR1 activates the N-terminal Toll-interleukin-1 receptor (TIR) domain of Arabidopsis NLR RPP1. We report a cryo-electron microscopy structure of RPP1 bound by ATR1. The structure reveals a
