The complete mitochondrial genome of Poecilia formosa (Poecilia, Cyprinodontidae) and phylogenetic studies of cyprinodontiformes.

ABSTRACT: We report the complete mitochondrial genome sequence of Poecilia formosa. The genome is found to be 16636?bp in length and has a base composition of A (29.59%), G (14.61%), C (28.26%), and T (27.54%). Similar to other Poecilia species, it contains a typically conserved structure including 13 protein-coding genes, 2 rRNA genes, 1 control region (D-loop), and 22tRNA genes. The proportion of coding sequences with a total length of 11,533?bp is 69.33%, which encodes 3837 amino acids. All protein-coding genes started with Met, ND1, CO1, ATP8, ATP6, CO3, ND4L, ND5, ND6 and CytB ended by TAA as a stop codon, ND2 and ND3 ended by TAG as a stop codon, CO3 and ND4 ended by a single T. The lengths of 12S ribosomal RNA is 948?bp, ranging from 70?bp to 1018?bp, and the lengths of 16S ribosomal RNA is 1674?bp, ranging from 1090?bp to 2764?bp. The length of control region is 879?bp, ranging from 15757?bp to 16636?bp, respectively. The complete mitochondrial genome sequence provided here would be useful for further understanding the evolution of ratite and conservation genetics of Poecilia formosa.
