Reference Genome Resource for the Citrus Pathogen Phytophthora citrophthora

Abstract

Phytophthora citrophthora is an oomycete pathogen that infects citrus. Its occurrence in citrus-growing regions worldwide is considered a major contributor to crop losses. This study presents a high-quality genome resource for P. citrophthora , which was generated using PacBio HiFi long-read high-throughput sequencing technology. We successfully assembled a 48.5 Mb genome containing 16,409 protein-coding genes from high-quality reads. This marks the first complete genome assembly of P. citrophthora , providing a valuable resource to enhance the understanding of pathogenic behaviour and fungicide sensitivity of this destructive citrus pathogen.
