A Phytophthora capsici effector suppresses plant immunity via interaction with EDS1

EDS1 (Enhanced Disease Susceptibility 1) plays a crucial role in both effector‐triggered immunity activation and plant basal defence. However, whether pathogen effectors can target EDS1 or an EDS1‐related pathway to manipulate immunity is rarely reported. In this study, we identified a Phytophthora capsici Avirulence Homolog (Avh) RxLR (Arg‐any amino acid‐Leu‐Arg) effector PcAvh103 that interacts with EDS1. We demonstrated that PcAvh103 can...
