* Complete mitochondrial genome of Macrognathus aculeatus (Synbranchiformes: Mastacembelidae).
- In this study, we cloned and sequenced the complete mitochondrial genome (mitogenome) of Macrognathus aculeatus. The genome is a circular molecule of 16,537 bp in length and consists of 13 protein-coding genes, 22 tRNA genes, 2 ribosomal RNA genes and 2 main non-coding regions (the control region and the origin of the light strand replication). The overall base composition of M. aculeatus is 30.03% for A, 26.46% for T, 28.72% for C and 14.79% for G, with a slight A + T bias of 56.49%. It has the typical vertebrate mitochondrial gene arrangement.
