黄单胞菌属细菌侵染广泛的农作物和野生植物，其中大多数物种是植物病害的罪魁祸首，这些病害对种子、植物和食品贸易产生全球经济和环境影响。黄单胞菌感染。引起各种各样的非特异性症状，使其难以识别。在系统发育上接近的菌株共存，但在表型上却截然不同，这给诊断带来了额外的挑战。关于未来气候变化情景的数据预测，流行病的严重性将增加，病原体将在地理上扩大，从而增加植物卫生服务的压力。在这方面，综合疾病管理战略的有效性在很大程度上取决于是否有快速、灵敏和具体的诊断方法。近年来基因组信息的积累促进了新DNA标记的识别，这是开发更灵敏和特异方法的基石。然而，该属的分类复杂性在诊断方面所代表的挑战，以及在同一细菌物种内，菌株组可能与不同的宿主物种相互作用的事实表明，仍有很长的路要走。本文就目前黄单胞菌的分子诊断和检测方法、黄单胞菌的分类和多样性研究以及分子诊断的基因组方法作一综述。
Bacteria in the genus Xanthomonas infect a wide range of crops and wild plants, with most species responsible for plant diseases that have a global economic and environmental impact on the seed, plant, and food trade. 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.
