Mitochondrial DNA A DNA Mapp Seq Anal. 2016;27(2):916-7. doi: 10.3109/19401736.2014.926484. Epub 2014 Jun 25.
Paecilomyces hepiali, belonging to the Eurotiales order Ascomycota, is an endoparasitic fungus that commonly exists in the natural Cordyceps sinensis anamorph stage. Here, we report the complete mitochondrial DNA sequences of P. hepiali for the first time. The genome is 24,245 bp in length, encoding 15 protein-coding genes (PCGs), 2 rRNA genes, 25 tRNA genes and 3 homing endonucleases. The overall AT composition is 73.37% and the average AT content of PCG, rRNA, tRNA and non-coding region are 74.21%, 66.07%, 62.83% and 75.96%, respectively. Phylogenetic analysis with eight Ascomycota species and thirteen Basidiomycota species revealed that P. hepiali is was more closely related to Cordyceps bassiana, Cordycep smilitaris and Cordyceps brongniartii. It is confirmed that P. hepiali is a derivative of Cordyceps sinensis. This study provided valuable information on the gene contents of the mitochondrial genome and would facilitate the study of function and evolution of P. hepiali.
蝙蝠蛾拟青霉属于子囊菌门散囊菌目，是一种内寄生真菌，通常存在于天然冬虫夏草的无性型阶段。在此，我们首次报道了蝙蝠蛾拟青霉的完整线粒体DNA序列。该基因组长度为24,245 bp，编码15个蛋白质编码基因（PCGs）、2个rRNA基因、25个tRNA基因和3个归巢内切酶。总体AT组成为73.37%，PCG、rRNA、tRNA和非编码区的平均AT含量分别为74.21%、66.07%、62.83%和75.96%。与8种子囊菌物种和13种担子菌物种的系统发育分析表明，蝙蝠蛾拟青霉与球孢白僵菌、蛹虫草和布氏虫草的关系更为密切。证实蝙蝠蛾拟青霉是冬虫夏草的衍生物。本研究为线粒体基因组的基因内容提供了有价值的信息，将有助于蝙蝠蛾拟青霉的功能和进化研究。
