Complete mitochondrial genome of Labeo rohita

Abstract

The complete mitochondrial genome of Labeo rohita, an important cultivable fish, was determined for the first time. The genome is 16,611 bp in length and consists of 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and one control region. The gene organisation and its order were similar to other vertebrates. The overall base composition on heavy strand was as follows A: 32.5%, G: 15.2%, C: 27.7%, T: 24.47%, and the A+T content 56.9%. The control region contains a microsatellite, (TA)₁₂, a putative termination-associated sequence and three conserved sequence blocks. This mitogenome sequence data would play an important role in population genetics and phylogenetics of Indian major carps.
