Powdery mildew, caused by Podosphaera leucotricha, is an economically important disease of apple and pear trees. A single monoconidial strain (PuE-3) of this biotrophic fungus was used to extract DNA for Illumina sequencing. Data were assembled to form a draft genome of 43.8 Mb consisting of 8,921 contigs, 9,372 predicted genes, and 96.1% of complete benchmarking universal single copy orthologs (BUSCOs). This is the first reported genome sequence of P. leucotricha that will enable studies of the population biology, epidemiology, and fungicide resistance of this pathogen. Furthermore, this resource will be fundamental to uncover the genetic and molecular mechanisms of the apple−powdery mildew interaction, and support future pome fruit breeding efforts.

白粉病（Podosphaera leucotricha）引起的白粉病是苹果树和梨树的一种重要的经济疾病。该生物营养真菌的单单孢子菌株（PuE-3）用于提取DNA，用于Illumina测序。数据被组装成一个43.8 Mb的基因组草图，它由8,921个重叠群，9372个预测基因和96.1％的完整基准通用单拷贝直系同源物（BUSCO）组成。这是首次报道的白斑假单胞菌基因组序列，可用于研究该病原体的种群生物学，流行病学和抗真菌剂。此外，该资源将是揭示苹果与粉虱相互作用的遗传和分子机制的基础，并支持未来的梨果育种工作。
