| + | [[https://www.uniprot.org/uniprot/EDS1C_ARATH EDS1C_ARATH]] Positive regulator of basal resistance and of effector-triggered immunity specifically mediated by TIR-NB-LRR (TNL) resistance proteins. 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).<ref>PMID:10077677</ref> <ref>PMID:11574472</ref> <ref>PMID:19578402</ref> <ref>PMID:20617163</ref> <ref>PMID:21434927</ref> <ref>PMID:22158819</ref> <ref>PMID:22316300</ref> <ref>PMID:24755512</ref> <ref>PMID:16040633</ref> | ||

| + | Plant nucleotide-binding leucine-rich repeat-containing (NLR) receptors with an N-terminal Toll/interleukin-1 receptor (TIR) domain sense pathogen effectors to enable TIR-encoded nicotinamide adenine dinucleotide hydrolase (NADase) activity for immune signaling. TIR-NLR signaling requires the helper NLRs N requirement gene 1 (NRG1), Activated Disease Resistance 1 (ADR1), and Enhanced Disease Susceptibility 1 (EDS1), which forms a heterodimer with each of its paralogs Phytoalexin Deficient 4 (PAD4) and Senescence-Associated Gene 101 (SAG101). Here, we show that TIR-containing proteins catalyze the production of 2'-(5''-phosphoribosyl)-5'-adenosine monophosphate (pRib-AMP) and diphosphate (pRib-ADP) in vitro and in planta. Biochemical and structural data demonstrate that EDS1-PAD4 is a receptor complex for pRib-AMP and pRib-ADP, which allosterically promote EDS1-PAD4 interaction with ADR1-L1 but not NRG1A. Our study identifies TIR-catalyzed pRib-AMP and pRib-ADP as a missing link in TIR signaling through EDS1-PAD4 and as likely second messengers for plant immunity. | ||
