Complete mitogenome of the entomopathogenic fungus Metarhizium rileyi

Abstract

In this study, the complete mitogenome of an entomopathogenic fungus Metarhizium rileyi was assembled and annotated. This circular mitogenome was 62,514 bp in length and consisted of 2 rRNA genes, 25 tRNA genes, 14 standard protein-coding genes of the oxidative phosphorylation system, and seven intergenic ORFs. Seven genes were invaded by a total of 22 introns, including atp9 (1), cob (4), cox1 (8), cox3 (2), nad1 (1), nad5 (3), and rnl (3 introns). These introns all belonged to the group I intron family but fell into four specific subgroups. Phylogenetic analysis based on mitochondrial nucleotide sequences confirmed M. rileyi in the family Clavicipitaceae, being most close to Metarhizium anisopliae.
