A new resource for research and risk analysis: the updated European Food Safety Authority database of Xylella spp. host plant species.

Following a series of requests for scientific advice from the European Commission starting in 2013, the European Food Safety Authority (EFSA) conducted pest risk assessment and created a comprehensive Xylella fastidiosa host plant database. The last update of the database, published in September 2018, includes information on host plants of both X. fastidiosa and X. taiwanensis, together with details on botanical classification, infection conditions, geographic location, pathogen taxonomy including information on subspecies, strain and sequence type, detection techniques and tolerant/resistant response of the plant. This updated database of host plants of Xylella spp. reported world-wide provides a key tool for risk management, risk assessment and research on this generalist bacterial plant pathogen.
