The complete mitochondrial genome of the Clarias fuscus (Siluriformes, Clariidae)

Abstract

We present the complete mitochondrial genome of the Clarias fuscus in this study. The mitochondrial genome is 16,525 bp 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 COXІ with GTG. Five types of termination codons revealed are TAA (COXІ, ATP8, ND4L), T (ND2, ND3, ND4, COXП, Cytb), AGG (COXШ), TA (ATP6), and TAG (ND1, ND5, ND6). Most genes are either abutted or overlapped and many features keep consistent with the other vertebrates.
