title: Update of the Xylella spp. host plant database

description: Following a request from the European Commission, in 2018 EFSA released a renovated database of host plant species of <em>Xylella</em> spp. (including both species<em> X. fastidiosa </em>and <em>X. taiwanensis</em>) together with a scientific report (EFSA, 2018). EFSA was tasked to maintain and update this database periodically. The mandate now covers the period 2021-2026 and EFSA is requested to release an update of the database twice per year. In January 2022 EFSA released the fifth update of the <em>Xylella</em> spp. host plant database (VERSION 5) with information retrieved from literature search up to June 2021 and recent Europhyt outbreak notifications (EFSA, 2022). The protocol applied for the extensive literature review, data collection and reporting, as well as results and lists of host plants are described in detail in the related scientific report (EFSA, 2022). The overall number of <em>Xylella</em> spp. host plants determined with at least two different detection methods or positive with one method (between: sequencing, pure culture isolation) reaches now 407 plant species, 185 genera and 68 families (category A – see section 2.4.2 of EFSA (2022)). Such numbers rise to 655 plant species, 293 genera and 88 families if considered regardless of the detection method applied (category E, see section 2.4.2 of EFSA (2022). The Excel files here attached represent the VERSION 5 of the <em>Xylella</em> spp. host plants database. For a detailed description of the information included in the database, please consult the related scientific report (EFSA, 2022). The Excel file “<em>Xylella</em> spp. host plants database – VERSION 5” contains several sheets: the LEGENDA (with extensive description of each table), the full detailed raw data of the <em>Xylella</em> spp. host plant database (sheet “observation”) and several examples of data extraction. Additional Excel files contain the lists of host plant species of <em>X. fastidiosa</em> (subsp. unknown (i.e. not reported), <em>fastidiosa</em>, <em>multiplex</em>, <em>pauca</em>, <em>morus</em>, <em>sandyi</em>, <em>tashke</em>, <em>fastidiosa/sandyi</em>) and <em>X. taiwanensis</em> infected naturally, artificially and in not specified conditions, and according to different categories (A,B,C,D,E – see section 2.4.2 of EFSA (2022)). The Excel file “new_host_plant_species_v5” contain the list of new host plant species added to the database in this new update. <strong>Question number: EFSA-Q-2017-00222</strong> <strong>Output number: EN-7040</strong> <strong>Correspondence: alpha@efsa.europa.eu</strong> <em>Bibliography:</em> EFSA (European Food Safety Authority), 2018.
