Abstract

Nucleotide-binding domain and leucine-rich repeat domaincontaining
(NLR) proteins are sentinels of plant immunity that
monitor host proteins for perturbations induced by pathogenic
effector proteins. Here we show that the Arabidopsis ZAR1 NLR
protein requires the ZRK3 kinase to recognize the Pseudomonas
syringae type III effector (T3E) HopF2a. These results support
the hypothesis that ZAR1 associates with an expanded ZRK
protein family to broaden its effector recognition spectrum.
