Sequencing and phylogenetic analysis of mitochondrial genome of Aspergillus cristatus

Abstract

Aspergillus cristatus are the dominantly present microorganisms in dark tea. The whole mitochondrial genome sequence of A. cristatus was sequenced and reported in this study. The mitochondrial genome in A. cristatushas a full length of 77,649 bp, which is reported to be the longest among the mitochondrial genomes of Aspergillus species. The basesincluding A (34.14％), T (37.64％), C (15.61％) and G (12.61％) are found in their genome. A total of 42 genes (15 protein-coding genes, lrRNA/srRNA and 25 tRNAs) are encoded by the mitochondrial genome of this fungus. Phylogenetic analysis showed a closest relationship betweenA. pseudoglaucusand the taxonomic status of A. cristatus.
