Abstract
Ophiocordyceps lanpingensis (O. lanpingensis) belongs to the genus Ophiocordyceps, which is often found in Yunnan Province, China. This species is pharmacologically important for the treatment of renal disorders induced by oxidative stress and an inadequate immune response. In the present study, the mitogenome of O. lanpingensis was determined to be a circular molecule 117,560 bp in length, and to have 31% G + C content and 69% A + T content. This mitogenome comprised 82% of the whole genome that codes for significant genes. The protein-coding regions of the O. lanpingensis mitogenome, containing 24 protein-coding genes, were associated with respiratory chain complexes, such as 3 ATP-synthase complex F0 subunits (atp6, atp8, and atp9), 2 complex IV subunits/cytochrome c oxidases (cox2 and cox3), 1 complex III subunit (cob), 4 electron transport complex I subunits/NADH dehydrogenase complex subunits (nad1, nad4, nad5, and nad6), 2 ribosomal RNAs (rns, rnl), and 11 hypothetical/predicted proteins, i.e., orf609, orf495, orf815, orf47, orf150, orf147, orf292, orf127, orf349, orf452, and orf100. It was noted that all genes were positioned on the same strand. Further, 13 mitochondrial genes with respiratory chain complexes, which presented maximum similarity with other fungal species of Ophiocordyceps, were investigated. O. lanpingensis was compared with previously sequenced species within Ophiocordycepitaceae. Comparative analysis indicated that O. lanpingensis was more closely related to O. sinensis, which is one of the most remarkable and expensive herbs due to its limited availability and the fact that it is difficult to culture. Therefore, O. lanpingensis is an important medicinal resource that can be effectively used for medicinal purposes. More extensive metabolomics research is recommended for O. lanpingensis.
