The complete mitochondrial genome of the Asiatic cavity-nesting honeybee Apis cerana (Hymenoptera: Apidae).

ABSTRACT: In the present study, we determined the complete mitochondrial DNA (mtDNA) sequence of Apis cerana, the Asiatic cavity-nesting honeybee. We present here an analysis of features of its gene content and genome organization in comparison with Apis mellifera to assess the variation within the genus Apis and among main groups of Hymenoptera. The size of the entire mt genome of A. cerana is 15,895 bp, containing 2 ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA (tRNA) genes and one control region. These genes are transcribed from both strands and have a nucleotide composition high in A and T. The contents of A+T of the complete genomes are 83.96% for A. cerana. The AT bias had a significant effect on both the codon usage pattern and amino acid composition of proteins. There are a t
