Approximately 33 types of commonly consumed fruits and vegetables are members of the family Cucurbitaceae, making it an important crop family worldwide. However, pathogen resistance to pesticides and fungicides has become a growing problem in cultivation practices. The identification of the effector proteins in each unique fungus–host pair would help toward the development of strategies for preventing the infection of important crops. In this study, we characterized the genome of Podosphaera xanthii, the fungal pathogen that causes powdery mildew disease in cucurbitaceous plants. A first-draft genome of 209.08 MB was assembled and compared with those of 25 other fungal pathogens, particularly for identifying candidate secreted effector proteins. This draft genome can serve as a valuable resource for future genomic and proteomic studies of P. xanthii and its host-specific pathogenesis.

葫芦科约有33种常用水果和蔬菜，是全世界重要的农作物科。然而，病原体对杀虫剂和杀真菌剂的抗性已成为栽培实践中日益严重的问题。在每个独特的真菌-宿主对中识别效应蛋白将有助于制定预防重要农作物感染的策略。在这项研究中，我们表征了黄荚鱼的基因组，是在葫芦科植物中引起白粉病的真菌病原体。组装了209.08 MB的第一稿基因组，并将其与其他25种真菌病原体的基因组进行了比较，特别是用于鉴定候选分泌的效应蛋白。该基因组草图可以为黄单胞菌及其宿主特异性发病机理的未来基因组和蛋白质组学研究提供宝贵的资源。
