Complete mitochondrial genome of the important bio-control fungus Purpureocillium lilacinum (Ophiocordycipitaceae, Hypocreales) and its phylogenetic analysis

Purpureocillium lilacinum is widely used as commercialized bio-control agents for controlling plant parasitic nematodes, as well as other insects and plant pathogens. In this study, the complete mitogenome of P. lilacinum was determined using the next-generation sequencing technology. The mitogenome is a circular molecule of 23,495 bp containing 15 protein-coding genes (PCGs), 2 rRNA (rnl and rns) genes and 22 tRNA genes. The overall base composition is 35.5% A, 36.0% T, 12.9% C and 15.6% G, with a CG content of 28.5%. Phylogenetic analysis inferred from 14 concatenated PCGs of 47 taxa shows that P. lilacinum is clustered with the genus Tolypocladium of Ophiocordycipitaceae and forms a separate clade with strong statistical support. This study contributes to our understanding about sytematics and evolutionary biology of cordycipitoid fungi.
