Abstract
In this study, we cloned and sequenced the complete mitochondrial genome of Barbatula nuda. The genome was found to be 16,619 bp in size with a mostly conserved structural organization when compared with that of other teleost fish. It contained 37 genes (13 protein-coding genes, 22 transfer RNA genes, and 2 ribosomal RNA genes) and 2 main non-coding regions (the control region and the origin of the light-strand replication). All protein-coding genes are initiated with ATG except for COX 1, which begin with GTG instead. However, the termination codons of 13 protein-coding genes varied with TAA, TA, T or TAG. The complete mitochondrial genome sequence is useful for phylogenetic analysis and studies of population genetics of B. nuda.
