<i>Penicillium griseofulvum</i> CF3 is a fungus isolated from healthy strawberry soil, with the potential to promote the growth of plants and enhance their resistance to diseases. However, the genome sequence of <i>P. griseofulvum</i> CF3 remains unclear. Therefore, we performed the whole-genome CCS sequencing of <i>P. griseofulvum</i> CF3 using the PacBio Sequel II platform. The assembled genome comprised 104 contigs, with a total length of 37,564,657 bp, encoding 13,252 protein-coding genes. Comprehensive functional annotation was performed using various BLAST databases, including the non-redundant (Nr) protein sequence database, Gene Ontology (GO), the Kyoto Encyclopedia of Genes and Genomes (KEGG), EuKaryotic Orthologous Groups (KOG), and the Carbohydrate-Active enZymes (CAZy) database, to identify and predict protein-coding genes, tRNAs, and rRNAs. The Antibiotics and Secondary Metabolites Analysis Shell (Antismash) analysis identified 50 biosynthetic gene clusters involved in secondary metabolite production within the <i>P. griseofulvum</i> CF3 genome. The whole-genome sequencing of <i>P. griseofulvum</i> CF3 helps us to understand its potential mechanisms in promoting plant growth and enhancing disease resistance, paving the way for the application of the CF3 strain in sustainable crop production.
