Abstract

The complete sequence of Pseudopodoces humilis mitochondrial genome was determined by using long PCR and conserved primers walking approaches. The results showed that the entire mitochondrial genome of Pseudopodoces humilis was 16 809 bp in length with 52.9% A+T content, and the 37 genes had the same gene order with that of Gallus gallus. All protein coding genes of the Pseudopodoces humilis mitochondrial genome started with ATG codon, except for COI with GTG. For terminate codon usage, most of genes terminate with codons TAA or TAG, ND1 and ND5 were AGA, COII was AGG, and the COIII and ND4 genes had an incomplete termination codon (T). The secondary structures of 22 tRNA were predicted, all tRNA can form typical secondary structure, except tRNASer ( AGN ) with an absence of DHU arm, and tRNAPhe with an extra nucleotide inserted in the TpsiC arm. The predicted secondary structures of 12S rRNA and 16S rRNA exhibit 47 helics in 3 structural domains and 60 helics in 6 domains, respectively. The control region of Pseudopodoces humilis located between tRNAGlu and tRNAPhe with 1 240 bp in length, and has structure domains found in that of the other birds.
