Infections by Xanthomonas spp. cause a wide variety of non-specific symptoms, making their identification difficult. The coexistence of phylogenetically close strains, but drastically different in their phenotype, poses an added challenge to diagnosis. Data on future climate change scenarios predict an increase in the severity of epidemics and a geographical expansion of pathogens, increasing pressure on plant health services. In this context, the effectiveness of integrated disease management strategies strongly depends on the availability of rapid, sensitive, and specific diagnostic methods. The accumulation of genomic information in recent years has facilitated the identification of new DNA markers, a cornerstone for the development of more sensitive and specific methods. Nevertheless, the challenges that the taxonomic complexity of this genus represents in terms of diagnosis together with the fact that within the same bacterial species, groups of strains may interact with distinct host species demonstrate that there is still a long way to go. In this review, we describe and discuss the current molecular-based methods for the diagnosis and detection of regulated Xanthomonas, taxonomic and diversity studies in Xanthomonas and genomic approaches for molecular diagnosis. specialized Xanthomonas molecular methods quarantine pests regulated non-quarantine pests EUROPE 076 084 114 9 4 862 [30 p.] 2021 https://www.documentation.ird.fr/hor/fdi:010081373 10.3390/microorganisms9040862 [F B010081373] https://www.documentation.ird.fr/hor/fdi:010081373 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2021-06/010081373.pdf IRD - Base Horizon / Pleins textes 2021-06-15 2025-02-24 fdi:010081373 fre
