Genome sequencing highlights the fungal sclerotium formation of medicinal fungi Polyporus umbellatus.

Abstract

Objectives: Polyporus umbellatus is a well-known medicinal fungus in Asia. Due to its long growth cycle, wild resources of P. umbellatus are rapidly declining. Research on P. umbellatus growth is scarce, thereby impeding the investigation into the mechanism of sclerotium formation. In this study, the whole genome sequence of P. umbellatus was assembled and annotated.

Data description: The generated genome was 79.74 Mb with an N50 of 969.73 Kbp, a GC content of 50.63%, encoding 10,864 protein-coding genes. Additionally, 82 ribosomal RNAs, 488 transfer RNAs, 25 small nuclear RNAs (snRNAs) and 741 micro RNA (miRNAs) were identified. This genomic resource will unveil molecular mechanisms of sclerotium formation and provides insight into the underlying molecular processes in medicinal fungi.
