title: Complete mitochondrial genome of Chinese lake gudgeon Sarcocheilichthys sinensis (Cypriniformes, Cyprinidae).
abstract: The complete mitochondrial genome of the Chinese lake gudgeon Sarcocheilichthys sinensis was first determined in this study. It is a circular DNA double strand of 16,684 bp in length, encodes genes for 13 proteins, 2 ribosomal RNA subunits, 22 transfer RNAs and an A + T-rich control region with the typical gene order in vertebrate mitogenomes. Overall nucleotide composition is 30.5% A, 26.6% C, 16.7% G and 26.3% T. Three start codons (ATG, GTG and ATA) and three stop codons (TAG, TAA and T) were found in all protein-coding genes. The tRNA-Ser(AGY) lacked the dihydrouridine arm and could not fold into typical cloverleaf secondary structure. The origin of L-strand replication was identified between the tRNA-Asn and tRNA-Cys genes.
