“…Research shows that, Exostoma species clustered with the clade containing the most genera of glyptosternine cat shes and then clustered with the more primitive groups Glaridoglanis and Glyptosternon (Gong et al 2021), this is consistent with the ndings of our study. Based on our study, it is possible that the Exostoma sp.…”

BackgroundAt present, the phylogenetic relationship of the Sisoridae is relatively chaotic. ObjectiveThis study systematically investigated the mitochondrial genomes (mitogenomes) of three species Creteuchiloglanis kamengensis, Glaridoglanis andersonii, and Exostoma sp., reconstruct the phylogenetic relationships of the family and to determine the phylogenetic position of Exostoma sp. within Sisoridae. MethodThe sample of three Sisoridae were collected and DNA were extracted. After sequencing, NOVOPlasty was used for sequence assembly. Annotate sequences with MITOS WebServer, tRNAscan-SE2.0, and NCBI database. MEGA was used for sequence analysis and Phylosuite was used for phylogenetic tree construction. ResultsThe lengths of the mitogenomes' sequences of C. kamengensis, G. andersonii, and Exostoma sp were 16,589, 16,531, and 16,529 bp, respectively. They contained one identical control region (D-loop), two ribosomal RNAs (rRNAs), 13 protein-coding genes (PCGs) and 22 transfer RNA (tRNA) genes among the three species. We applied two approaches, Bayesian Inference (BI) and Maximum Likelihood (ML), to build phylogenetic trees. Our ndings revealed that the topological structure of both ML and BI trees exhibited signi cant congruence. Speci cally, the monophyly of Sisorinae and Glyptosternoids was robustly supported in the ML tree. ConclusionIt also proves that the current phylogenetic relationship of Sisoridae is relatively chaotic, and provides new molecular biology data support for the reconstruction of the phylogenetic relationship of Sisoridae. This study will be of great scienti c value to the study of phylogeny and the genetic variation of Sisoridae.

“…Assemblies of the clean reads obtained de novo were conducted using SPAdes 3.9 [ 11 ] to obtain the complete circular mitogenomes. The annotations were conducted using the MitoZ toolkit [ 12 ] according to the vertebrate mitochondrial codon system, and then checked manually with reference to the published mitogenome of Exostoma gaoligongense [ 10 ]. Composition of nucleotides, relative synonymous codon usage (RSCU), and interspecific genetic divergence were calculated using Mega 7.0 [ 13 ].…”

“…To date, the complete mitogenome sequences have been determined for dozens of glyptosternine catfishes. However, very few documents of the mitogenomics of Exostoma species have been published [ 10 ]. Therefore, the complete mitogenomes from species of Exostoma are required to improve the accuracy of mitogenome features of this genus, as well as to promote the analysis of their phylogenetic positioning and evolutionary history.…”

The genus Exostoma is a group of stenotopic and rheophilic glyptosternine catfishes distributed in South and Southeast Asia. So far, comprehensive studies on mitogenomics referring to this genus are very scarce. In this study, we first sequenced and annotated the complete mitochondrial genomes of Exostoma tibetanum and Exostoma tenuicaudatum—two sympatric congeners from the lower Yarlung Tsangpo River, Tibet, China. The mitogenomes of both species contained 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes, one light-strand origin of replication, and one control region, with lengths of 16,528 bp and 16,533 bp, respectively. The mitogenome architecture, nucleotide composition, and codon usage of protein-coding genes were almost identical between the two Exostoma species, although some estimated parameters varied. Phylogenetic analysis strongly supported the monophyly of Exostoma in the subfamily Glyptosternae, and Exostoma tibetanum had the closest relationship to Exostoma tenuicaudatum. The divergence time estimation demonstrated that these two species diverged approximately 1.51 Ma during the early Pleistocene, which was speculated to be triggered by the river system changes caused by the uplift of the southeastern Tibetan Plateau. Selection pressure analyses indicated that all protein-coding genes of Exostoma species underwent a strong purifying selection, while minority positive sites from NADH dehydrogenase complex genes were detected. These findings are expected to promote our understanding of the molecular phylogeny of the genus Exostoma and provide valuable mitogenomic resources for the subfamily Glyptosternae

Glyptothorax pallozonus Lin, 1934 is a small benthic fish belonging to the Sisoridae family that is distributed in the Dongjiang and Rongjiang Rivers of China. In the present study, we sequenced and characterized the complete mitochondrial genome of G. pallozonus for the first time. The complete mitogenome of G. pallozonus is 16,542 bp in length and includes 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), two ribosomal RNA (rRNAs), and a control region (CR). The mitogenome architecture was identical to that of other teleosts. Maximum likelihood (ML) phylogenetic analysis strongly supported the monophyly of Glyptothorax , which contains two clades. These results advance our understanding of the molecular phylogeny of the genus Glyptothorax .
