title: Complete mitochondrial genome of the "floppy-wing" morph reproductive termite, Reticulitermes labralis (Isoptera: Rhinotermitidae).
abstract: The complete mitochondrial genome of Reticulitermes labralis (Isoptera: Rhinotermitidae) was determined for its nucleotide sequence of 16 113 bp. Its gene content and organization were identical with other Reticulitermes species. The 13 protein-coding genes (PCGs) have typical ATN initiation codon. But, the stop codons were TAA, TAG and an incomplete termination codon (T) abutting an adjacent tRNA gene. Twenty-two tRNA genes, in addition to tRNASer(AGN) replaced lacking of the DHU stem with a simple loop, showed the typical clover-leaf secondary structure. The A + T-rich region was 1311 bp in length with 65.98% A + T content. In addition to the A + T-rich region, non-coding sequences of the mtDNA genome harbored 17 intergenic spacers. There were three complete repeats of repeat A in CR, which were not discovered in other termite species. Phylogenetic tree based on the 11 complete mitochondrial genome sequences of closely related termite species accords well with morphological phylogenetic analysis.
