The complete mitochondrial genome of Labeo catla (Hamilton, 1822) using long read sequencing

Labeo catla is a widely cultured species in monoculture and polyculture systems of the Indian subcontinent. In this study, the complete mitochondrial genome sequence of catla was reconstructed from Oxford Nanopore sequence data. The mitochondrial genome is 16,600 bp in length (accession no. is MN830943) which is larger than the previously reported catla mitogenomes. Like other vertebrate mitochondrial genomes, it has 13 protein-coding genes, 22 tRNAs, 2 rRNAs and a putative control region. Most of the mitogenes are encoded on H-strand. Phylogenetic analysis showed that Labeo catla is more closely related to Labeo rohita than other labeo species. The catla mtgenome reported here will facilitate population genetics, phylogenetics and molecular taxonomy of Indian major carps.
