The gene sequence of xopE4 is similar to XopE2 (avrXacE3), but due to its low amino acid sequence identity (31%) was considered a different effector that can discriminate between X. citri and //X. fuscans// pv. aurantifolii strains, both causing citrus bacterial canker (Moreira //et al//., 2010; Dalio //et al//., 2017).
