Rearrangement of trnQ-trnM in the mitochondrial genome of Allantus luctifer (Smith) (Hymenoptera: Tenthredinidae)

Abstract

The complete mitochondrial genome of the Allantus luctifer (Smith) (Hymenoptera: Tenthredinidae: Allantinae) is reported in this study (GenBank accession No. KJ713152). This is the first mitochondrial genome from the subfamily Allantinae and the first completely sequenced mitochondrial genome from the Tenthredinoidea. The length of this mitochondrial genome is 15,418 bp with an A+T content of 81.13%, including 13 protein-coding, 2 rRNA and 22 tRNA gene, and an A+T-rich region (Table 1). Gene arrangement is identical to the other two mitochondrial genomes of tenthredinoid species in nearly all region as in the pupative ancestral arrangement of insects. The ancestral pattern of “A+T-rich region-trnI(+)-trnQ(-)-trnM(+)” was rearranged to “trnM(-)-trnQ(+)-A+T-rich region-trnI(+)”, which is novel to the Hymenoptera. All protein-coding genes start with ATN start codon. Eleven protein-coding genes stop with termination codon TAA, whereas one protein-coding gene uses incomplete stop codon TA and one uses T. The A+T-region is 463 bp long with an A+T content of 86.6%.
