title: The complete mitochondrial genome of the nematode endoparasitic fungus Hirsutella minnesotensis.
abstract: In this study, the complete mitochondrial genome of a nematode fungal pathogen, Hirsutella minnesotensis, is sequenced. The circular mitogenome of H. minnesotensis is 52,245 bp in length and consists of 2 rRNA, 25 tRNA and 14 standard protein-coding genes of the oxidative phosphorylation system as well as four additional free-standing ORFs encoding for an endonuclease or a hypothetical protein. Seven genes (rnl, cob, cox1, nad3, nad4, nad4L and nad5) are invaded by group I or unclassified introns, and these introns carry ORFs of ribosomal protein S3 and GIY-YIG/LAGLIDADG endonucleases or hypothetical proteins. Evidence of intron degeneration is significant for the nad4L intron and cox1-i1 due to unexpected stop codons and/or frame shifting. Phylogenetic analysis based on concatenated protein sequences confirms H. minnesotensis as a member of the fungal order Hypocreales. In this study, we present the complete mitogenome sequence of H. minnesotensis, which is the first complete mitogenome of the family Ophiocordycipitaceae.
