The mitochondrial genome of the western bean cutworm, Striacosta albicosta (Lepidoptera: Noctuidae).

ABSTRACT: The complete 15,553?bp mitochondrial genome of the western bean cutworm, Stricosta albicosta, (Lepidoptera: Noctuidae) was assembled from paired end Illumina HiSeq2500 read data. Annotation showed 13 predicted protein coding genes (PCGs), 22 tRNAs and 2 rRNAs have an order and orientation typical of insect mitochondrial genomes, and the derived rearrangement of tRNA-Met, -Ile and -Gln upstream of nad2 as in other Lepidoptera. A 79.3% A?+?T content resulted in a bias for codons with A or T in the 3rd position, and prevalence of synonymous substitutions suggest the effects of purifying selection on the mitochondrial genome sequence. Two microsatellite repeat motifs, (CA)₁₀(AT)₁₉ and (AT)₁₂, are respectively located in intergenic spaces between tRNA-Glu and -Phe and tRNA-Leu and 16S rRNA. Mitochondrial phylogenomics was able to resolve sub-families within the Noctuidae, and suggest analogous analyses may be applicable across other lepidopteran Families.
