Comparative mitogenomic and phylogenetic characterization on the complete mitogenomes of Talaromyces (Penicillium) marneffei

Abstract

We report the complete mitochondrial DNA (mtDNA) sequences of four Talaromyces marneffei strains and performed comparative genomic and phylogenetic analyses. The gene orders of the four mtDNAs are identical to the previously published mtDNA of strain PM1 (nad4l, nad5, nad2, atp9, cob, nad1, nad4, atp8, atp6, nad6, cox3, rps, cox1, nad3, cox2). Phylogenetic analysis showed that the four mtDNAs were clustered with that of PM1 with high bootstrap support. Compared to mtDNA of PM1, the only non-synonymous mutation was located in nad2 (T505M) of strain PM26. Synonymous single nucleotide polymorphisms were observed at eight positions in the four mtDNAs.
