Complete mitogenome of Hemiculter leucisculus (Cyprinidae: Cultrinae).

The complete mitogenome was first determined for a minnow Hemiculter leucisculus in this study. It is 16,622 bp in length and has 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and 1 control region. Overall nucleotide base composition is 30.4% A, 27.10% C, 17.10% G and 25.40% T. All the tRNA genes can fold into the typical clover-leaf secondary structures, except the tRNA-Ser2 which loses the dihydrouridine arm and is replaced with one 11 bp loop. The origin of light-strand replication (OL) was found between the tRNA-Asn and tRNA-Cys genes while the termination associated sequence (TAS) and the conserved sequence blocks (CSB1-3) were found in the control region.
