Complete mitochondrial genome and phylogenic analysis of Rhinogobius cliffordpopei (Perciformes, Gobiidae)

Mao

et al. 2022

Rhinogobius wuyanlingensis is endemic to the upper reaches of Feiyunjiang river basin. In this article, the complete mitochondrial genome (mtDNA) for this freshwater goby was first determined. Sequence analysis showed the genome consisted of 13 protein-coding genes, 22 tRNA genes, two ribosomal RNA genes, and two main non-coding regions (the control region and the origin of the light strand replication). This circular molecule was 16,491 bp in length with a slight AT bias of 53.5%. In the phylogenetic tree, R. wuyanlingensis was closer to Rhinogobius brunneus , Rhinogobius yonezawai, Rhinogobius flumineus , and Rhinogobius cliffordpopei . The mitochondrial genome of R. wuyanlingensis reported here would provide basal molecular data for evolution, taxonomy, and population genetics of Rhinogobius .

Characteristic and phylogenetic analyses of mitochondrial genome for Rhinogobius filamentosus (Teleostei: Gobiidae: Gobionellinae), an endemic species in China

Liu

et al. 2022

This study sequenced and annotated the complete mitochondrial genome sequence of Rhinogobius filamentosus , an endemic species in China. The complete mitochondrial genome was 16,510 base pairs long and contained 13 protein-coding genes (PCGs, 11,414 bp), 22 tRNA genes (1,555 bp), two rRNA genes (2,615 bp), two non-coding regions (D-loop: control region displacement loop, 478 bp; OL: origin of L-strand replication, 30 bp). The overall base composition of the genome was estimated to be T (25.4%), C (30.2%), A (27.6%) and G (16.7%), showing an AT bias (53%). Phylogenetic analyses revealed that the genus Rhinogobius included two clades. For one clade, R. filamentosus clustered with R. duospilus , and they formed a sister-group relationship with other ten Rhinogobius species. This work would be essential in revealing the evolutionary relationships in Gobionellinae.

“…Similar to most vertebrate mitogenomes, four pairs of protein-coding genes, namely ATP8-ATP6 , ATP6-CO3 , ND4L-ND4 , and ND5-ND6 , showed the overlapping which spanned 7, 1, 7,4, respectively (Wang et al. 2019 ; Yang et al. 2020 ).…”

Phylogenetic relationship and characterization of the complete mitochondrial genome sequence ofOpsarius caudiocellatus(Cypriniformes: Danionidae: Chedrinae)

Cao

et al. 2022

In this paper, we first report the complete mtDNA sequence of Opsarius caudiocellatus with the main aim of providing a basis for further researches of this species. Assembly circular mitogenome was 16,534 bp long encoded 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, and one control region. The gene nucleotide composition was estimated to be 28.1% A, 25.2% T, 18.6% G, 28.1% C. A maximum-likelihood (ML) phylogenetic tree was reconstructed using the 13 concatenated mitochondrial protein-coding genes of O. caudiocellatus and other 19 species of the subfamily Chedrinae. Result of the phylogenetic analysis revealed that O. caudiocellatus was well grouped with Barilius barila. This study could enrich genetic resources and be helpful to studies on evolution and conservation genetics for O. caudiocellatus.
