摘要
We present the complete mitochondrial genome of the Clarias fuscus in this study. The mitochondrial genome is 16,525bp in length and consists of 13 protein-coding genes, two rRNA genes, 22 tRNA genes and a control region. The nucleotide compositions of the light strand are 31.17% of A, 27.54% of C, 25.34% of T, and 14.95% of G. With the exception of ND6 and eight tRNA genes, all other mitochondrial genes are encoded on the heavy strand. All the protein-coding genes begin with an ATG initiation codon except for COX with GTG. Five types of termination codons revealed are TAA (COX, ATP8, ND4L), T (ND2, ND3, ND4, COX?, Cytb), AGG (COX?), TA (ATP6), and TAG (ND1, ND5, ND6). Most genes are either abutted or overlapped and many features keep consistent with the other vertebrates.
