Annual Conference 2021 (Online)

The EuroXanth COST Action held its 4th Annual Conference on “Integrating science on Xanthomonadaceae for integrated plant disease management in Europe” online from 28 to 30 June 2021 (three afternoons at Paris time). This conference served as a platform to exchange knowledge and to share technical knowhow with respect to members of the Xanthomonadaceae family. The deadline for Registration was Sunday, May 23. The program and book of abstracts can be downloaded from our website: Program & Book of Abstracts (ISBN 978-86-7834-377-3).

The conference addressed topics of all four Working Groups:
Session 1: Diagnostics & Diversity – Population Structure
Session 2: Pathogen Biology
Session 3: Genetic Resistance – Host Defence
Session 4: Disease Management – Vector Control

All four topics were well represented. In total, 29 invited talks and 45 poster presentations were given. Unfortunately, the COVID-19 pandemic did not allow to meet in person. On the other hand, switching to an online format allowed joining with more colleagues than it would have been possible with an on-site conference. Yet, we missed social activities that would give ample time for interesting discussions and often lead to new collaborations. No doubt that this large gathering of scientists from Europe and beyond working on Xanthomonas and Xylella can be considered as a great success of the EuroXanth COST Action. The success is also linked to the great job that was done by the organisers, Prof. Dr. Aleksa Obradović (University of Belgrade) and Dr. Katarina Gašić (Institute for Plant Protection and Environment, Belgrade), both from Serbia. We would also like to thank the staff from ARIA.ONE for their professional support in organising this event. Thanks a lot to all of you for your commitment!
