Phytophthora plurivora can affect a range of ecologically and silviculturally important tree species, including European beech (Fagus sylvatica), a common late successional tree species native to Europe. Here, we report on the high-quality genome of P. plurivora strain TJ71 (CBS 124093). We sequenced it using Oxford Nanopore MinION and PacBio Sequel II long-read sequencing with 80x coverage, chromatin conformation capture (Hi-C) sequencing with 400x coverage and DNBSEQ 150bp paired-end short reads sequencing with 200x coverage. This complex sequencing approach allowed assembly of the genome at the chromosome level. Specifically, the Phytophthora plurivora genome resulted in 18 scaffolds of 47 Mbp total size with 95% completeness of the eukaryotic gene set as implemented in BUSCO. This is a considerable improvement relative to the previous NCBI reference genomes P. plurivora (NMPK00000000.1) with ~41 Mbp organized in 1,898 scaffolds with 93.8% eukaryotic BUSCO completeness. This high quality genome provides a valuable resource for further evolutionary, epidemiological and population genomic studies.
