The complete mitochondrial genome and phylogenetic analysis of Turricula nelliae spurius (Gastropoda, Turridae). Issue 1 (2nd January 2019) - Fu, Zeqin
Abstract: Herein, we first determined the complete mitochondrial genome of Turricula nelliae spurius in this study. The circular mitochondrial genome is 16, 450â€‰bp in length, consisting of 13 protein-coding genes, 22 tRNA genes, and two ribosomal RNA genes. The nucleotide composition is 15.0% of C, 15.8% of G, 38.0% of T, and 31.2% of A. The control region is between tRNA Phe and COX3 genes and has 1, 144â€‰bp. In 13 protein-coding genes, three genes (nad2, nad4, atp6) start with ATA, the other 10 genes are with ATG. For the stop codon, nad3 and nad4l end with TAG, other 11 genes end with TAA. The phylogenetic tree was constructed based on 13 protein-coding genes of T. nelliae spurius and other 11 species using the Neighbor-joining method, and the result showed that T. nelliae spurius is closed to the Gemmuloborsonia moosai and clustered in the same branch with its same family speciesâ€" Lophiotoma cerithiformis . The mitochondrial genome would be helpful for the study of population genetic and phylogenetic analysis of the family Turridae.
