Update of the Xylella spp. host plant database - Systematic literature search up to 31 December 2025

This scientific report provides an update of the Xylella spp. host plant database, aiming to provide information and scientific support to risk assessors, risk managers and researchers dealing with Xylella spp. Upon a mandate of the European Commission, EFSA created and regularly updates a database of host plant species of Xylella spp. The current mandate covers the period 2021-2026. This report is related to the fourteenth version of the database published in Zenodo in the EFSA Knowledge Junction community, covering literature published from 1 July 2025 up to 31 December 2025 and recent Europhyt outbreak notifications. Informative data have been extracted from 41 selected publications. Twenty-seven new host plants were identified and added to the database. They were naturally infected by X. fastidiosa, X. fastidiosa subsp. multiplex or X. fastidiosa subsp. fastidiosa in Argentina, the United States, Portugal and Spain. No additional data were retrieved for X. taiwanensis, and no additional multilocus sequence types (STs) were identified worldwide. No new information on the tolerant/resistant response of plant species to X. fastidiosa infection was added to the database. The Xylella spp. host plant species were listed in different categories based on the number and type of detection methods applied for each finding. The overall number of Xylella spp. host plants determined with at least two different X. fastidiosa detection methods, or positive with one method (between sequencing and pure culture isolation (category A)), reaches now 471 plant species, 213 genera and 72 families. Such numbers rise to 755 plant species, 329 genera and 93 families if considered regardless of the detection methods applied (category E).
