The complete mitochondrial genome of an orb-weaver spider Araneus angulatus (Araneae: Araneidae).

ABSTRACT

The complete mitochondrial genome of an orb-weaver spider Araneus angulatus is 14,205 bp in length and contains 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs, and a control region. The A + T content of the major strand is 75.4%. Nine of the protein-coding genes are initiated by typical ATN codons, one gene (COI) starts with TTA and other three genes (ND6, COII, and COIII) begin with TTG. The truncated stop codon (T) occurs in ND3, ND4L, and ND6, whereas the rest ten genes end with the canonical stop codon (TAA and TAG). Fifteen tRNAs lack the potential to form the typically cloverleaf-shaped secondary structure. The control region is 649 bp in length and contains a long tandem repeat region. The result of phylogenetic analysis shows that the relationship of A. angulatus was close to the species in the same family Araneidae.
