Bacterial spot is an endemic seedborne disease responsible for recurring outbreaks on tomato and pepper around the world. The disease is caused by four diverse species, Xanthomonas gardneri, Xanthomonas euvesicatoria, Xanthomonas perforans, and Xanthomonas vesicatoria. There are no commercially available disease-resistant tomato varieties, and the disease is managed by chemical/biological control options, although these have not reduced the incidence of outbreaks. The disease on peppers is managed by disease-resistant cultivars that are effective against X. euvesicatoria but not X. gardneri. A significant shift in composition and prevalence of different species and races of the pathogen has occurred over the past century. Here, I attempt to review ecological and evolutionary processes associated with the population dynamics leading to disease emergence and spread. The goal of this review is to integrate the knowledge on population genomics and molecular plant–microbe interactions for this pathosystem to tailor disease management strategies.

利用番茄和辣椒上黄单胞菌的生态进化动力学来解决旧病害的新问题

细菌性斑点病是一种地方性种子传播疾病,是世界各地番茄和辣椒反复爆发的原因。该病由四种不同的物种引起,即黄单胞菌黄单胞菌黄单胞菌、穿孔黄单胞菌黄单胞菌。没有市售的抗病番茄品种,该病是通过化学/生物控制方法来控制的,尽管这些并没有降低爆发的发生率。辣椒上的病害由抗病品种控制,这些品种对X. euvesicatoria有效,但对X. gardneri无效. 在过去的一个世纪里,病原体的不同物种和种族的组成和流行发生了重大变化。在这里,我试图回顾与导致疾病出现和传播的种群动态相关的生态和进化过程。本综述的目的是整合有关该病理系统的群体基因组学和分子植物-微生物相互作用的知识,以制定疾病管理策略。
