The complete genome sequence and phylogenetic analysis of the mitochondrial DNA of the wood-decaying fungus Fomitopsis palustris

摘要

The complete mitochondrial genome sequence of the wood-decaying fungus Fomitopsis palustris (Basidiomycete, Agaricomycotina) was determined by next-generation sequencing technology. The complete sequence of the circular mitochondrial DNA of F. palustris was 63,479 bp in length with a 75.98% AT content. The mitochondrial genome encoded 14 conserved proteins, 2 ribosomal RNAs, 26 transfer RNAs, and 19 additional open reading frames. The coxI and cob genes contained six and one group I introns, respectively, and encoded eight open reading frames, including seven intron-encoded endonucleases. The complete mitochondrial genome of F. palustris presented herein represents the first such report for brown rot basidiomycetes. In addition, the BLAST score ratio and phylogenetic analysis may open new avenues to understanding the evolutionary status of this fungus .
