Complete mitochondrial genome of Copadichromis virginalis (Cichlidae).

ABSTRACT: In this study, we report the complete mitochondrial genome of Copadichromis virginalis (Cichlidae fish). The mitochondrial genome is 16?704?bp in length and has a base composition of A (27.6%), T (30.1%), C (15.7%) and G (26.6%), demonstrating a slight bias of high AT content (57.6%). It contains 35 genes (13 protein-coding genes, 22 tRNAs and two rRNAs) and a non-coding A?+?T rich region (D-loop region). The mitochondial genome of Copadichromis virginalis presents a clear bias in nucleotied composition with a positive AT-skew and a negative GC-skew. Except for ND6 gene, all other protein-coding genes were located on the H-strand. ND4 gene and ND4L gene were overlapped by 5?bp, ATP8 gene and ATP6 gene were overlapped by 9?bp. The nucleotide sequence of 13 protein-coding genes of Copadichromis virginalis and other 19 Cichlidae species were used for phylogenetic analysis. The result indicated Copadichromis virginalis a close relationship with species Astatotilapia calliptera.

The complete mitochondrial genome of Lamprologus signatus (Perciformes: Cichlidae).

Project description:In this study, the complete 16,583 bp mitochondrial genome of Lamprologus signatus (Poll, 1952) was determined from a specimen sourced from Lake Tanganyika. The mitogenome contains 37 genes [13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, and 22 transfer RNA (tRNA) genes] and a putative control region, which consists of 27.1% A, 27.0% T, 29.9% C, and 16.0% G, with a total G + C content of 45.9%. A maximum likelihood phylogenetic tree based on mitochondrial PCGs suggested that L. signatus is clustered with members of the tribes Haplochromini and Tropheini. As this is the first report of the entire mitogenome in the tribe Lamprologini, the complete mitochondrial sequence information of L. sigantus will be useful in determining phylogenetic relationships of Pseudocrenilabrinae tribes.

Complete mitochondrial DNA genome of banded cichlid Heros severus Heckel, 1840 (Perciformes: Cichlidae).

Project description:In this study, we sequenced the complete mitochondrial genome of Heros severus Heckel, 1840 (Perciformes, Cichlidae). This mitochondrial genome, consisting of 16,577 base pairs (bp), contains 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs, and 2 noncoding control regions (control region and origin of light-strand replication) as those found in other vertebrates. Control region, of 917 bp in length, is located between tRNAPro and tRNAPhe. Within the control region, typical conserved domains, such as the termination-associated sequence (TAS), central, and conserved sequence blocks domains were identified. The overall base composition of the heavy strand shows 27.6% of T, 26.3% of C, 29.3% of A, and 16.8% of G, with a slight A + T rich feature (56.9%). The complete mitogenome data provide useful genetic markers for the studies on the molecular identification, population genetics, phylogenetic analysis, and conservation genetics.

Characterization and phylogenetic analysis of the complete mitochondrial genome of Mango tilapia (Sarotherodon galilaeus: Cichlidae).

Project description:BackgroundSarotherodon galilaeus (Linné, 1758) is a member of the family Cichlidae, which is considered the most important aquaculture freshwater species endemic to Africa and the Middle East. The genetics and molecular biology of this species are rare. This requires more comprehensive mitochondrial genomes-based phylogenetics to enhance understanding of the relationship and delineate this species.Methods and resultsHere, we assembled the complete mitogenome of S. galilaeus using Illumina high-throughput sequencing technology. The mango tilapia mitogenome was 16,631 bp in length with an AT composition of 53.4% and 46.4% GC content. It encodes 37 genes comprising two ribosomal RNA genes (rRNAs), 22 transfer RNA genes (tRNAs), and 13 protein-coding genes (PCGs) as well as the D-loop known as the control region. The phylogenetic tree was conducted to provide a relationship within the haplotilapiine lineage based on the maximum likelihood method, and the newly sequenced S. galilaeus was clustered with other Sarotherodon species.ConclusionOur results provide a new perception of the genetic basis of S. galilaeus species for further research on systematics, evolution, population genetics, and molecular ecology.

The complete mitochondrial genome of Sarotherodon galilaeus (Linnaeus, 1758) (Perciformes: Cichlidae) and its phylogenetic placement.

Project description:Sarotherodon galilaeus (Linnaeus, 1758), a cichlid species that is naturally distributed in African and Eurasian waters, was introduced in many Asian countries for aquaculture. To date, rare genetic studies focused on this species have hindered our understanding of this species. Here, we reported the complete mitochondrial genome of S. galilaeus that was sequenced using next-generation sequencing technology. The resulting mitogenome of S. galilaeus was 16,630 in length and comprised 13 protein-coding genes (PCG), 22 transfer RNA (tRNA) genes, 2 ribosomal RNA genes (rRNA), and one control region (D-loop). Phylogenetic analysis indicated that Oreochromini species contained two lineages (I and II) and S. galilaeus clustered with Oreochromis aureus rather than other Sarotherodon species.

Taxonomic investigation of the zooplanktivorous Lake Malawi cichlids Copadichromis mloto (Iles) and C. virginalis (Iles).

Project description:The taxonomic status of the zooplanktivorous cichlids Copadichromis mloto and C. virginalis has been confused since their original descriptions by lles in 1960. Whilst two forms of C. virginalis, 'Kaduna' and 'Kajose', were distinguished in the type material, C. mloto has not been positively identified since its original description. Here we re-examined the types as well as 54 recently collected specimens from multiple sampling locations. Genome sequencing of 51 recent specimens revealed two closely related but reciprocally monophyletic clades. Geometric morphological analysis indicated that one clade morphologically encompasses the type specimens of C. virginalis identified by Iles as the Kaduna form, including the holotype, whilst the other clade encompasses not only the paratypes identified as the Kajose form, but also the type series of C. mloto. Given that all three forms in Iles's type series are from the same locality, that there are no meristic or character states to differentiate them and that there are no records of adult male C. mloto in breeding colours, we conclude that the Kajose form previously identified as C. virginalis represents relatively deeper bodied sexually active or maturing individuals of C. mloto.Supplementary informationThe online version contains supplementary material available at 10.1007/s10750-022-05025-1.

Low genetic and morphometric intraspecific divergence in peripheral copadichromis populations (perciformes: cichlidae) in the lake Malawi basin.

Project description:Peripheral isolated populations may undergo rapid divergence from the main population due to various factors such as a bottleneck or a founder effect followed by genetic drift or local selection pressures. Recent populations of two economically important Copadichromis species in Lake Malombe, a satellite lake of Lake Malawi, were neither genetically nor morphometrically distinct from their source populations in the main lake. Evidence was found for a founder effect which had a different impact on the genetic composition of the two species. In addition, the increased fishing pressure in Lake Malombe may have led to a reduction of the body sizes of both species.

Characterization and phylogenetic analysis of the complete mitochondrial genome of the firemouth cichlid, Thorichthys meeki (Perciformes: Cichlidae).

Project description:Here, we report information on the complete mitochondrial genome of the firemouth cichlid, Thorichthys meeki (Brind 1918). Illumina HiSeq genome sequencing produced the assembly of a circular mitogenome of 16,527 base pairs (bp) from T. meeki consisting of 46.8% GC nucleotides, 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and a putative control region as shown in the typical teleost gene composition. The gene order of the T. meeki mitogenome was identical to that of other cichlid species. A maximum likelihood phylogenetic tree based on mitochondrial PCGs showed a close relationship of T. meeki with Thorichthys aureus (Gunther 1862) within Heroini tribe.
