Disruption by bacterial effector of EDS1-TIR-NB-LRR resistance protein interactions constitutes the first step in resistance activation (PubMed:22158819). Acts redundantly with salicylic acid to regulate resistance gene-mediated signaling (PubMed:19578402). Triggers early plant defenses and hypersensitive response independently of PAD4, and then recruits PAD4 to potentiate plant defenses through the accumulation of salicylic acid (PubMed:11574472). Nuclear localization is essential for basal and TNL-conditioned immunity and for reprogramming defense gene expression, while cytoplasmic EDS1 is required to induce a complete immune response (PubMed:20617163). Heterodimerization with PAD4 and/or SGA101 is necessary for TNL-mediated effector-triggered immunity (PubMed:24331460). Contributes to nonhost resistance against E.amylovora (PubMed:22316300). Loss of EDS1-PAD4 interaction compromises basal but not TNL-triggered resistance (PubMed:21434927). Necessary for systemic acquired resistance (SAR) signal generation and perception (PubMed:24755512). Has no direct lipase activity (PubMed:16040633). Putative lipase activity is dispensable for immune functions (PubMed:24331460).
