Complete mitochondrial genome of Aspergillus japonicus from the built environment and its phylogenetic analysis

Abstract

The complete mitochondrial genome of the important black aspergilli species Aspergillus japonicus was determined using the next-generation sequencing technology. The circular mitogenome of A. japonicus YFCC 8801-W is 48,001 bp in length with a GC content of 27.1%, containing 14 protein-coding genes (PCGs), 4 ORFs, 24 transfer RNA (tRNA) genes and 2 ribosomal RNA (rns and rnl) genes. Phylogenetic analysis based on 14 PCGs showed that A. japonicus was clustered in the A. section Nigri clade of the genus Aspergillus (Aspergillaceae) and formed a separate clade with high credible support. This study provides valuable information for further exploration of mitochondrial evolution in the order Aspergillales.
