Improved whole genome sequence of Phytophthora capsici generated by long-read sequencing.

The soil-borne oomycete Phytophthora capsici is the most destructive pathogen of vegetable crops and is responsible for substantial economic losses worldwide. Here, we present an improved genome assembly of P. capsici generated by Oxford Nanopore long-read sequencing (for de novo assembly) and Illumina short-read sequencing (for polishing). The genome of P. capsici is 100.5 Mb in length (GC content = 50.8%) and contains 26,069 predicted protein-coding genes. The whole genome of P. capsici is assembled into 194 scaffolds, 90% of which are larger than 300 kb. The N50 scaffold length and maximum scaffold length are 1.0 and 4.1 Mb, respectively. The whole genome sequence of P. capsici will broaden our knowledge of this pathogen and enhance our understanding of the molecular basis of its pathogenicity, which will facilitate the development of effective management strategies.
