Genome Sequence Resource of Phytophthora vignae, the causal agent of stem and root rot of cowpea

The causal agent of stem and root rot of cowpea, Phytophthora vignae, is a widely distributed species of Phytophthora genus. Here, we generate a high-quality complete genome assembly of P. vignae strain PSY2020 (89.39 Mb, N50: 2.99 Mb) from China using Oxford Nanopore Technologies (ONT) sequencing. The genome assembly completeness evaluated by BUSCO was 94.51% at eukaryote level.

We identified 42.54% repeat sequences and a total of 20,536 protein-encoding genes, of which 15,184 genes could be annotated. And we also identified 924 candidate RXLR effectors in the genome assembly. The described genome sequence will provide a valuable resource for better understanding of pathogenicity mechanisms of P. vignae, and shedding light on uncovering phylogenetical classification of Phytophthora species.
