Characterization of the complete mitochondrial genome of Mucor indicus Lendn. 1930 (Mucorales: Mucoraceae), isolated from the wine fermentation system

Mucor indicus Lendn. 1930 has been widely used in food fermentation; however, its mitochondrial genome characteristics are not well understood. In this study, the complete mitochondrial genome of M. indicus was obtained, which was 61,400 bp in length with a GC content of 33%. The M. indicus mitochondrial genome was found to contain 14 core protein-coding genes, four free-standing ORFs, 18 intronic ORFs, 26 tRNAs, and two rRNA genes. Phylogenetic trees were generated for 25 early-differentiated fungi using the Bayesian inference (BI) method, which demonstrated that M. indicus is closely related to Mucor piriformis. This study provides useful information for the classification and evolution of Mucor species or other early-differentiated fungi.
