Peronospora destructor is an obligate biotrophic oomycete that causes downy mildew on onion (Allium cepa). Onion is an important crop worldwide, but its production is affected by this pathogen. We sequenced the genome of P. destructor using the PacBio sequencing platform, and de novo assembly resulted in 74 contigs with a total contig size of 29.3 Mb and 48.48% GC content. Here, we report the first high-quality genome sequence of P. destructor and its comparison with the genome assemblies of other oomycetes. The genome is a very useful resource to serve as a reference for analysis of P. destructor isolates and for comparative genomic studies of the biotrophic oomycetes.

洋葱霜霉病的病因是Peronospora破坏基因的高质量基因组装配。

Peronospora破坏物是专性的生物营养卵菌，可引起洋葱霜霉病（葱属）。洋葱是世界范围内重要的农作物，但其生产受到这种病原体的影响。我们使用PacBio测序平台对P.destructor基因进行了测序，并且从头组装产生了74个重叠群，总重叠群大小为29.3 Mb，GC含量为48.48％。在这里，我们报告的第一个高质量的P. destructor的基因组序列，并将其与其他卵菌的基因组组装进行比较。基因组是非常有用的资源，可作为分析腐烂假单胞菌分离物和生物营养型卵菌的比较基因组研究的参考。
