The complete mitochondrial genome of the entomopathogenic fungus Beauveria pseudobassiana (Ascomycota, Cordycipitaceae) was determined and found to be 28,006 bp in length. It encodes genes for 14 proteins, 2 ribosomal RNA subunits, 25 transfer RNAs with the synteny identical to those of B. bassiana and B. brongniartii. The overall base composition is 36.7% A, 35.8% T, 15.3% C and 12.2% G with an AT content of 72.5%. Group-І introns were found in large rRNA gene (rnl) and cox2 gene that include rps3 gene and putative GIY-YIG homing endonuclease, respectively. The mitochondrial genome of B. pseudobassiana will contribute to the investigation of the phylogenetic relationship, taxonomic resolution and biogeography of Beauveria.
测定了昆虫病原真菌拟白僵菌（子囊菌门，虫草科）的完整线粒体基因组，发现其长度为28,006 bp。它编码14种蛋白质、2个核糖体RNA亚基和25个转运RNA的基因，其同线性与球孢白僵菌和布氏白僵菌相同。总体碱基组成为36.7%A、35.8%T、15.3%C和12.2%G，AT含量为72.5%。在大核糖体RNA基因（rnl）和cox2基因中发现了Ⅰ组内含子，分别包含rps3基因和假定的GIY-YIG归巢内切核酸酶。拟白僵菌的线粒体基因组将有助于研究白僵菌的系统发育关系、分类分辨率和生物地理学。
