Our knowledge in topics of the XylVec project has already been usefully applied within the Expert Working Group of the European Plant Protection Organization (EPPO), where Tanja Dreo participated in the creation of a diagnostic protocol for determination of the bacterium Xylella fastidiosa. A common protocol enables harmonization of diagnostic laboratories and comparability of results between countries. See the published protocol PM 7/24 (2) Xylella fastidiosa, 2016. EPPO Bull 46, 463–500. doi:10.1111/epp.12327.
