Characterization of the mitochondrial genome of Phyllomimus sp. (Orthoptera: Pseudophyllidae)

Abstract

The nearly complete mitochondrial genome (mitogenome) without tRNA-Met and with a partial A + T-rich region of phyllomimus sp. has been sequenced with the length of 15,543 bp. We found 140 bp-long intergenic spacers (IGSs) which located between tRNA-Gln and ND2, while this region should be tRNA-Met in most orthopteran mitogenomes. The content of As, Ts, Cs Gs and AT in the mitogenome is 37.3%, 32.5%, 20.6%, 9.5% and 69.8%, respectively. All protein-coding genes start with typical ATN codon except for ND1, which initiates with TTG codon instead, and end with either complete TAA/TAG codons or incomplete T(aa) codons. Phylogenetic analysis indicated that genetic distances of phyllomimus sp. and Orophyllus montanus was closer than other species.
