 Using RT-PCR analyses, XopE1 from //X. euvesicatoria// was found to be upregulated by HrpG and HrpX (Thieme //et al//., 2007). The promoter of xopE1<sub>XCV85-10</sub> contains a PIP BOX (Thieme //et al//., 2007). Using RT-PCR analyses, XopE1 from //X. euvesicatoria// was found to be upregulated by HrpG and HrpX (Thieme //et al//., 2007). The promoter of xopE1<sub>XCV85-10</sub> contains a PIP BOX (Thieme //et al//., 2007).

 +Transcriptome analysis (RNA-seq) and qRT-PCR revealed that //avrXacE1// (//xopE1//) gene expression is downregulated in a //X. citri// pv. //citri// Δ//phoP// mutant, indicating that PhoP is a positive regulator of //xopE1// expression (Wei et al., 2019).

-XopE1 was found to physically interact with tomato 14-3-3s (TFT) and is also associated to VirK secreted by T2SS and with a possible role in the modulation of plant immune response during the infection process (Assis //et al//., 2017). +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).
