Nod-like receptors (NLRs) belong to AAA+ ATPases and act as ATP-dependent molecular switches, which detect activity of pathogens. Function of a large class of plant NLRs with Toll-like domain (TNL) is fully dependent on a class of EDS1-like proteins specific to seed plants. EDS1 (Enhanced Disease Susceptibility 1) – like proteins are defined as fusions of two domains: lipase-like a/b hydrolase domain and an a-helical bundle domain specific to the EDS1 family. In Arabidopsis, RRS1-RPS4 TNL signaling is dependent on the nuclear localization of EDS1 and formation of heterodimers between EDS1 and its sequence-related partners, PAD4 and SAG101. Here, we deposited results of affinity purification and LC-MS analyses are deposited for the EDS1 complexes after triggering NLR-dependent immune responses in Arabidopsis leaves. As a negative control, plants expressing GFP-tagged Telomere Repeat Binding 1 were used. The complexes were purified from nuclear enriched fractions of Arabidopsis complementation lines infected with the TNL-triggering bacteria.
