The complete mitochondrial genome of Poropanchax normani and phylogenetic studies of Cyprinodontidaes.

ABSTRACT: The complete mitochondrial genome of the Cyprinodontiformes fish Poropanchax normani was studied in this study. The size of the entire mitochondrial genome was 16,878 bp, and the total length of the encoding sequence was 11,435 bp, accounting for 67.75%, encoding 3800 amino acids in total. Genome base compositions were: A was 27.30%, C was 28.30%, G was 16.17%, and T was 28.23%. ND2 and CO1 started with GTG, and other protein-coding genes started with ATG. ND1, ND2, and ND3 ended with TAG, respectively, CO2 and ND4 ended with a single T, and other PCGS ended with TAA. The ribosomal RNA lengths of 12S and 16S were 950 bp and 1690 bp, respectively. The control area (D-loop) was 1194 bp in size and ranged from 15,685 to 16,878 bp. It showed negative GC skew value (-0.2728) and negative AT skewness (-0.0168). Phylogenetic analysis showed that P. normani was most closely related to Xenotoca eiseni. The complete sequence of the mitochondrial genome will provide a new perspective for classification and help to draw a more complete picture of species diversity within the Cyprinodontiformes.

Project description:The Paracheirodon axelrodi is an important freshwater fish in the Amazon basin of South America, more expensive than Paracheirodon innesi. Here, we describe the complete 17,100 base pair (bp) mitochondrial genome of Paracheirodon axelrodi mohavensis. The mitogenome has a nucleotide base composition of A (29.62%), T (29.41%), G (15.39%), and C (25.62%), and encodes 13 protein subunits, 22 tRNAs, a 12S rRNA of 952 bp and 16S rRNA of 1665 bp, and a 1433 bp D-loop control region, each located in the conserved mtDNA structure typical for Characidae fishes. All protein-coding genes have initiation codons of ATG, ND1, ND2, CO2, ND3, ND4L, ND5, ND6 and Cytb ended by TAA as a stop codon, ND4 ended by AGA as a stop codon, CO1 ended by AGG as a stop codon, ATP8 and CO3 ended by TAG as a stop codon, ATP6 ended by ATT as a stop codon. This characterised mitogenome may help inform management practices for Paracheirodon axelrodi mohavensis by facilitating future studies on how allopatric populations of this imperilled species are evolving across refuge habitats.
