The complete mitochondrial genome of Lebiasina astrigata (Characiformes: Lebiasinida) and phylogenetic studies of Characiformes

Mitochondrial DNA Part B, 2019
In the present study, the complete mitochondrial DNA sequence of was determined for the first time. The mitochondrial genome of Lebiasina astrigata is a circular molecule of 16,899 bp in size and contains 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and 2 control regions. The base composition is 30.02% for A, 15.34% for G, 27.24% for C, and 27.
