Structure of the central plant immunity signaling node EDS1 in complex with its interaction partner SAG101

Template:ABSTRACT PUBMED 24331460

Function

[SG101_ARATH] Acyl hydrolase that triggers the leaf senescence onset. Can use triolein as substrate to produce oleic acids.^{[1] [2] [3] [4]} Involved in the EDS1-dependent intrinsic and indispensable resistance signaling pathway; together with PAD4, required for programmed cell death triggered by RPS4 in response to avirulent pathogens (e.g. Pseudomonas syringae pv. tomato strain DC3000 and Hyaloperonospora parasitica isolates CALA2 and EMWA1) and in restricting the growth of virulent pathogens (e.g. H. parasitica isolates NOCO2 and P.syringae pv. tomato strain DC3000 avrRps4). Regulates the nuclear localization of EDS1. Essential for the RPP8/HRT-mediated resistance to the turnip crinkle virus (TCV). Involved in the post-invasion resistance to Phakopsora pachyrhizi in the mesophyll.^{[5] [6] [7] [8]}
