Complete mitochondrial genome of the important entomopathogenic fungus Cordyceps tenuipes (Hypocreales, Cordycipitaceae)

Abstract

Cordyceps tenuipes is a worldwide entomopathogenic fungus and is famous as the edible and medical value in East Asian nations. In the present study, the high-quality whole-genome of C. tenuipes was sequenced on the Illumina sequencing platform. The complete mitochondrial genome of this fungus was assembled as a single circular dsDNA of 31386 bp, including 15 protein-coding genes, 2 ribosomal RNA genes and 22 transfer RNA genes. The overall base composition of C. tenuipes is 36.6% A, 36.4% T, 11.8% C, 15.2% G, with a CG content of 27%. Phylogenetic analyses based on concatenated protein sequences from 27 taxa of five families within the order Hypocreales were conducted using Maximum likelihood (ML) and Bayesian inference (BI) methods. It is revealed that C. tenuipes is more closely related to C. militaris in the family Cordycipitaceae. This study would facilitate the future investigation of genetics, evolution and function of cordycipitoid fungi.
