-//Agrobacterium//-mediated expression of XopE1 triggers a fast cell-death reaction in non host //Nicotiana// plants revealing that XopE1 is recognized by //Nicotiana//. Its membrane localization delays the detection by the plant surveillance system and contributes to inactivate plant immune responses (Thieme //et al//., 2007). XopE1 was associated to different grades of cytotoxicity and intermediate growth inhibition on yeast and caused phenotypes ranging from chlorosis to cell death when transiently expressed via //Agrobacterium// in either host or non-host plants (Salomon //et al//., 2011; Adlung //et al//., 2016). XopE1 mutants grew to equivalent titers as wild-type //X. euvesicatoria// in tomato leaves indicating that is not required for bacterial multiplication in planta. However, XopE1 was found to be required to suppress chlorosis and tissue collapse at very late stages of //Xanthomonas// infection. XopE1 together with XopE2 and XopO may function redundantly to inhibit //X//. //euvesicatoria//-induced chlorosis in tomato leaves (Dubrow //et al//., 2018).+//Agrobacterium//-mediated expression of XopE1 triggers a fast cell-death reaction in non host //Nicotiana// plants revealing that XopE1 is recognized by //Nicotiana//.

 XopE1 was found to physically interact with tomato 14-3-3s (TFT) (Dubrow //et al.//, 2018). In addition, XopE1 was predicted to interact with VirK, which is secreted by the T2SS and for which a possible role in the modulation of plant immune response during the infection process was suggested (Assis //et al//., 2017). XopE1 was found to physically interact with tomato 14-3-3s (TFT) (Dubrow //et al.//, 2018).
