Complete Mitochondrial Genome of the Grass Moth Glyphodes quadrimaculalis (Lepidoptera: Crambidae)
Glyphodes quadrimaculalis (Lepidoptera: Crambidae) feed on a root tuber of Cynanchum wilfordii (Asclepiadaceae) that is one of the most famous traditional medicines in Korea. The genus Glyphodes includes ~130 species distributed worldwide, so the complete mitochondrial genome (mitogenome) would be helpful for bio-identification, biogeographic studies, and multigene-based phylogeny. The 15,255-bp long G. quadrimaculalis genome comprises 37 typical genes and one large non-coding region, with the typical arrangement found in Lepidoptera. Of the 13 protein coding genes (PCGs), 12 begin with typical start codons found in insect mitochondrial PCGs, but the COI gene starts with atypical CGA. One of the noteworthy features of the genome includes the presence of a 51-bp long non-coding space sequence located between tRNAGln and ND2 that reveals high sequence homology (71.4%) to the neighboring ND2 gene, indicating the origin of the region by partial duplication of the ND2 gene.
