Abstract

Xylaria hypoxylon is a noticeable black fungus, and also habitual to cluster on rotting wood. In this study, the high-quality whole-genome of X. hypoxylon strain SFY20170806 was sequenced on the Illumina sequencing platform. The complete mitochondrial genome of X. hypoxylon was assembled and annotated. The single circular structure of 129,366 bp length is the largest species found in the order Xylariales. The overall GC content is 29.7% and gene composition includes 13 protein-coding genes (PCGs), 30 transfer RNA genes(tRNA), 2 ribosomal RNA genes(rRNA) and 6 open reading frames (ORF). Phylogenetic tree was constructed to validate the evolutionary relationship based on the complete mitogenomes from twelve taxa of four species of Xylariales, four species of Hypocreales, two species of Helotiales, one species of Microascales and X. hypoxylon. Phylogenetic analysis demonstrated that X. hypoxylon has a special evolutionary status and close genetic relationship with Annulohypoxylon stygium.
