Complete mitochondrial genome of the medicinal fungus Ophiocordyceps sinensis.

ABSTRACT: As part of a genome sequencing project for Ophiocordyceps sinensis, strain 1229, a complete mitochondrial (mt) genome was assembled as a single circular dsDNA of 157,510 bp, one of the largest reported for fungi. Conserved genes including the large and small rRNA subunits, 27 tRNA and 15 protein-coding genes, were identified. In addition, 58 non-conserved open reading frames (ncORFs) in the intergenic and intronic regions were also identified. Transcription analyses using RNA-Seq validated the expression of most conserved genes and ncORFs. Fifty-two introns (groups I and II) were found within conserved genes, accounting for 68.5% of the genome. Thirty-two homing endonucleases (HEs) with motif patterns LAGLIDADG (21) and GIY-YIG (11) were identified in group I introns. The ncORFs found in g
