Abstract

Abstract: Rochia nilotica is a common marine gastropod species in family Tegulidae. At present, less molecular information of genus Rochia was reported. In the present study, we first determined the complete mitochondrial genome of R. nilotica . The mitochondrial sequence was 16, 966 bp in length and encoded for 35 metazoan mitochondrial genes, including 13 protein-coding genes, 20 transfer RNAs, and two rRNAs. The overall nucleotide composition is 32.2% A, 17.3% C, 17.8% G, and 32.7% T. Thirteen protein-coding genes started with ATG codons, and 10 protein-coding genes used termination codon of TAA, whereas the remaining three had a termination codon of TAG. Three overlaps between adjacent genes were found in the mitochondrial gene. The phylogenetic relationships of 17 mitochondrial sequences based on the concatenated nucleotide sequences of 13 protein-coding genes showed that R. nilotica was closely related to Tectus pyramis .
