The results provide compelling evidence for the preferential utilization of either signaling component by particular R genes and thus define at least two disease resistance pathways and suggest that strong dependence on EDS1 or NDR1 is governed by R protein structural type rather than pathogen class.
Arabidopsis MAP Kinase 4 Negatively Regulates Systemic Acquired Resistance
Pre- and Postinvasion Defenses Both Contribute to Nonhost Resistance in Arabidopsis
It is reported that Arabidopsis PEN2 restricts pathogen entry of two ascomycete powdery mildew fungi that in nature colonize grass and pea species.
Direct interaction between the Arabidopsis disease resistance signaling proteins, EDS1 and PAD4
The Arabidopsis EDS1 and PAD4 genes encode lipase‐like proteins that function in resistance (R) gene‐mediated and basal plant disease resistance and two functions are proposed: the first is required early in plant defence, independently of P AD4, and the second recruits PAD 4 in the amplification of defences, possibly by direct EDS2–PAD4 association.
Effector-triggered immunity: from pathogen perception to robust defense.
In plant innate immunity, effector-triggered immunity displays remarkable robustness against pathogen disturbance, in part by employing compensatory mechanisms within the defense network.
Salicylic Acid–Independent ENHANCED DISEASE SUSCEPTIBILITY1 Signaling in Arabidopsis Immunity and Cell Death Is Regulated by the Monooxygenase FMO1 and the Nudix Hydrolase NUDT7[W]
Two new immune regulators are defined through analysis of corresponding Arabidopsis loss-of-function insertion mutants, and it is found that SA antagonizes initiation of cell death and stunting of growth in nudt7 mutants.
EDS1, an essential component of R gene-mediated disease resistance in Arabidopsis has homology to eukaryotic lipases.

The results suggest that EDS1 functions upstream of salicylic acid-dependent PR1 mRNA accumulation and is not required for jasmonic acid-induced PDF1.2 mRNA expression.

An RPP-nonspecific locus called EDS1 appears to be a necessary component of the resistance response specified by several RPP genes and is likely to function upstream from the convergence of disease resistance pathways in Arabidopsis.
Arabidopsis EDS1 Connects Pathogen Effector Recognition to Cell Compartment–Specific Immune Responses

EDS1 behaves as an effector target and activated TIR-NB-LRR signal transducer for defenses across cell compartments and is molecularly connected to RPS4 recognition of bacterial effector AvrRps4 to defense pathways.
