Project description:The complete mitochondrial genome of Ancherythroculter wangi was determined. The mitochondrial genome, consisting of 16,622 base pairs (bp), encoded 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs and a non-coding control region, as those found in other Ancherythroculter species. These results can provide useful data for further studies on taxonomic status, molecular systematics, and stock evaluation.
Project description:This study determined the mitochondrial genome sequence of the stonefly, Kamimuria wangi. In order to investigate the relatedness of stonefly to other members of Neoptera, a phylogenetic analysis was undertaken based on 13 protein-coding genes of mitochondrial genomes in 13 representative insects. The mitochondrial genome of the stonefly is a circular molecule consisting of 16,179 nucleotides and contains the 37 genes typically found in other insects. A 10-bp poly-T stretch was observed in the A+T-rich region of the K. wangi mitochondrial genome. Downstream of the poly-T stretch, two regions were located with potential ability to form stem-loop structures; these were designated stem-loop 1 (positions 15848-15651) and stem-loop 2 (15965-15998). The arrangement of genes and nucleotide composition of the K. wangi mitogenome are similar to those in Pteronarcys princeps, suggesting a conserved genome evolution within the Plecoptera. Phylogenetic analysis using maximum likelihood and Bayesian inference of 13 protein-coding genes supported a novel relationship between the Plecoptera and Ephemeroptera. The results contradict the existence of a monophyletic Plectoptera and Plecoptera as sister taxa to Embiidina, and thus requires further analyses with additional mitogenome sampling at the base of the Neoptera.
