Powdery mildews (PMs) are important plant pathogens causing widespread damage. Here, we report the first draft genome of , the causative agent of PM of flowering dogwood, . The assembled genome was 63.5 Mbp and resulted in formation of 19,442 contigs (N50 = 11,686 bp) that contained an estimated 6,860 genes with a genome coverage of 62×. We found 102 candidate secreted effector proteins (CSEPs) in similar to genes that are potentially involved in disease development. This draft genome is an initial step for understanding the evolutionary history of the PMs and will also provide insight into evolutionary strategies that led to the wide host expansion and environmental adaptations so effectively employed by the PM lineages.
白粉菌是一类重要的植物病原菌，可导致广泛的损害。在这里，我们报道了, , 的第一个基因组草案，, 是红叶石楠白粉病的病原体。组装的基因组大小为 63.5 Mbp，形成了 19442 个重叠群（N50=11686 bp），包含估计有 6860 个基因，基因组覆盖率为 62×。我们在 中发现了 102 个候选分泌效应蛋白（CSEP） 类似的 基因，这些基因可能参与了疾病的发展。该基因组草案是了解白粉菌进化历史的第一步，也将为了解导致白粉菌谱系广泛宿主扩张和有效环境适应的进化策略提供线索。
