Abstract
In this study, the first complete mitochondrial genome (mitogenome) of the mold mite, Tyrophagus putrescentiae was determined by long PCR and primer walking methods. The mitogenome was 13,288 bp in length, including 13 typical invertebrate protein-coding genes, 18 transfer RNA genes and 2 ribosomal RNA genes. The overall base composition of the heavy strand is 22.5% A, 48.2% T, 13.2% C and 16.1% G, with a A+T bias. Stop codon was incomplete for ND4 gene and ND2. Gene overlaps were observed between 12 pairs of the contiguous genes in T. putrescentiae. The study also displayed that four tRNAs were missed for T. putrescentiae. Researches on mitogenome would further contribute to resolving phylogenetic position and interrelationships of Tyrophagus.
