The complete mitochondrial genome of the Songpu mirror carp, Cyprinus carpio.

ABSTRACT: In this study, the complete mitochondrial genome sequences of Cyprinus carpio (strain Songpu) were reported for the first time. The genome is found to be 16 582?bp in length accurately using the next-generation sequencing technology and bioinformatics tools, and it has a base composition of A (31.9%), G (15.7%), C (27.5%) and T (24.9%), indicating that the percentage of A?+?T (56.8%) was higher than G?+?C (43.2%). The whole genome contains a typically conserved structure, which includes 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and one control region (D-loop). To obtain the phylogenetic relationship between Songpu mirror carp and other species, 11 mitochondrial genomes were used for phylogenetic analysis. The result shows the Songpu mirror carp is closely related to Cyprinu carpio carpio that is also a member of the genus Cyprinu.

Project description:BackgroundAquaporins (Aqps) are integral membrane proteins that facilitate the transport of water and small solutes across cell membranes. Among vertebrate species, Aqps are highly conserved in both gene structure and amino acid sequence. These proteins are vital for maintaining water homeostasis in living organisms, especially for aquatic animals such as teleost fish. Studies on teleost Aqps are mainly limited to several model species with diploid genomes. Common carp, which has a tetraploidized genome, is one of the most common aquaculture species being adapted to a wide range of aquatic environments. The complete common carp genome has recently been released, providing us the possibility for gene evolution of aqp gene family after whole genome duplication.ResultsIn this study, we identified a total of 37 aqp genes from common carp genome. Phylogenetic analysis revealed that most of aqps are highly conserved. Comparative analysis was performed across five typical vertebrate genomes. We found that almost all of the aqp genes in common carp were duplicated in the evolution of the gene family. We postulated that the expansion of the aqp gene family in common carp was the result of an additional whole genome duplication event and that the aqp gene family in other teleosts has been lost in their evolution history with the reason that the functions of genes are redundant and conservation. Expression patterns were assessed in various tissues, including brain, heart, spleen, liver, intestine, gill, muscle, and skin, which demonstrated the comprehensive expression profiles of aqp genes in the tetraploidized genome. Significant gene expression divergences have been observed, revealing substantial expression divergences or functional divergences in those duplicated aqp genes post the latest WGD event.ConclusionsTo some extent, the gene families are also considered as a unique source for evolutionary studies. Moreover, the whole set of common carp aqp gene family provides an essential genomic resource for future biochemical, toxicological, physiological, and evolutionary studies in common carp.
