The mitochondrial genome analysis of Isaria tenuipes (Hypocreales: Cordycipitaceae)

Authors: Zhang, Sheng-Li and wei, Lei and Luan, Feng-Gang

The mitochondrial genome of Isaria tenuipes, strain TTZ2017-3, was sequenced on the Illumina Hiseq 4000 and the PacBio Sequel Sequencer and annotated. The genome is 66703bp in length, encoding 15 conserved protein-coding genes (PCGs) including ribosomal protein S3, two rRNA genes and 26 tRNA genes. The nucleotide composition of I. tenuipes mitochondrial genome was 39.1% of A, 35.6% of T, 11.2% of C, 14.2% of G, 74.7% of AþT content. Phylogenetic analysis with other Hypocreales species revealed that I. tenuipes was more closely related to Cordyceps militaris, separated from Lecanicillium muscarium, Paecilomyces hepialid, and Beauveria species with Cordyceps teleomorph. This study provided valuable information on the gene contents of the mitochondrial genome and would facilitate the study of function and evolution of Isaria.
