Genome Sequence Resource of Fusarium oxysporum Strain PkF01: The Causative Agent of Rhizome Rot of Polygonatum kingianum

Abstract

Fusarium oxysporum strain PkF01 is the causal agent of Polygonatum kingianum rhizome rot. Here, we report, for the first time, the genome assemblies of the F. oxysporum strain PkF01 using the PacBio Sequel system. We obtained a total base number of 51.27 Mb in 87 contigs. The number of scaffolds and scaffold N50 were 86 and 2.46 Mb, with a 47.55% GC content. The number of coding sequences was 17,265, with total length of 36.61 Mb, average length of 1.77 kb, and a gene density of 0.34 kb. A total of 11,447, 14,734, 10,759, and 4,434 genes were annotated using the Pfam, COG, GO, and KEGG databases, respectively. A total of 764, 335, 1,572, 216, 4,245, 1,591, 2,242, and 1,926 genes were annotated using the CAZy, CYP450, DFVF, CARD, PHI, SignalP, TCDB, and TMHMM databases, respectively. Collinearity analysis showed that the PkF01 genome shared more homologous genomic regions with F. oxysporum f. sp. lilii strain Fol39 than with F. oxysporum f. sp. lycopersici strain Fol4287, indicating that the PkF01 genome is more closely related to the Fol39 rather than the Fol4287 genome. The high-quality genome sequences of PkF01 will provide a valuable resource for not only investigating both the pathogenicity mechanism and host specificity in F. oxysporum but also exploring disease control measures.
