摘要

The filamentous fungus Arcopilus aureus (Sordariale: Chaetomiaceae) is notable for its multi-domain significance across agriculture, medicine, and industry. In this study, we generated a chromosome-level nuclear genome and a complete circular mitogenome for A. aureus by integrating data from next-generation sequencing, PacBio HiFi, and Hi-C technologies. The final nuclear genome assembly spans 33.77 Mb (GC content: 57.67%), and was organized into seven chromosomal-sized scaffolds (only one gap) with an N50 size of 5.09 Mb and BUSCO completeness of 95.91%. A total of 10,282 protein-coding genes, 228 non-coding RNAs, and ~1.77 Mb of repetitive elements were predicted in the nuclear genome. By contrast, the mitogenome of A. aureus is 33,820 bp in length, with a GC content of 25.96%. It harbors 15 typical mitochondrial protein-coding genes, one unidentified ORF, two rRNAs (small subunit rns and large subunit rnl), and 28 tRNAs. This high-quality genome assembly provides a valuable resource for understanding the ecology, genetics, and evolution of A. aureus, which facilitates elucidating its mechanisms of biocontrol, infection, and metabolite synthesis.
