The first draft genome sequence of Penicillium adametzioides FBCC-F1417, isolated from freshwater plant litter in South Korea

Penicillium adametzioides is a phylogenetically distinct and ecologically adaptable member of the genus Penicillium. Reports from different isolates and contexts describe postharvest pathogenicity, biocontrol potential, and production of marine-derived metabolites. Because these roles come from different strains and environments, species-level generalizations remain uncertain. To address the lack of genomic data while avoiding overgeneralization, we sequenced and annotated P. adametzioides FBCC-F1417, a freshwater plant-litter isolate from Korea, to provide a strain-resolved genomic resource that supports comparative and pangenomic studies across P. adametzioides and related taxa. We assembled the genome of P. adametzioides FBCC-F1417 into 12 contigs totaling 40.47 Mb, with an N50 of 5.16 Mb and GC content of 45.52%. BUSCO analysis showed 99.2% completeness, indicating a high-quality assembly. Gene prediction identified 13,643 protein-coding genes, of which 5,959 proteins (40.7%) were functionally annotated. Repeat analysis showed that 6.62% genome consisted of repetitive elements. Secondary metabolite analysis predicted 86 biosynthetic gene clusters, including NRPS, PKS, terpene, and hybrid types. These features should be interpreted as attributes of FBCC-F1417 rather than definitive species-wide characteristics, and the annotated genome is intended as a reference for downstream comparative and pangenomic analyses that will test which features are conserved across P. adametzioides.
