“…All GC skew values are negative with the exception of the ND6 gene of C. kumu , which had a positive GC skew. This result suggests that more Ts and Cs are present in most PCGs, which is consistent with most previous observations 34, 39 .…”

“…In contrast, these enrichments are slightly higher compared with those of C. poecilopus (51.4%) and Cottus hangiongensis (51.3%). Both of the highest A + T contents (60.9% and 59.8%) were detected in the control region, which is consistent with previous research on other fish 20, 34 . Additionally, the AT skew (0.0277) for the C. kumu mitogenome is slightly positive, indicating a higher occurrence of As to Ts, and its GC skew (−0.2925) is negative, indicating a higher content of Cs than Gs.…”

“…The AT skew (0.0287) and GC skew (−0.2895) for the L. microptera mitogenome are identical to those of the L. microptera mitogenome. These findings are similar to all sequenced Scorpaeniformes mitogenomes to date, except for Cottus poecilopus , Cottus hangiongensis and Satyrichthys amiscus 20, 34 , which have a negative AT skew.…”

“…The CR in L. microptera spanned 838 bp with 59.3% A + T content and shows a slightly positive AT skew (0.0181) and a negative GC skew (−0.1144). The A + T content of the two mitogenomes is lower than most of the other Scorpaeniformes species to date 33, 34 . Several conserved sequence blocks (CSBs) are observed in the control regions of teleost fish, which could play important roles in mitochondrial metabolism 42 .…”

The mitochondrial genome (mitogenome) can provide useful information for analyzing phylogeny and molecular evolution. Scorpaeniformes is one of the most diverse teleostean orders and has great commercial importance. To develop mitogenome data for this important group, we determined the complete mitogenomes of two gurnards Chelidonichthys kumu and Lepidotrigla microptera of Triglidae within Scorpaeniformes for the first time. The mitogenomes are 16,495 bp long in C. kumu and 16,610 bp long in L. microptera. Both the mitogenomes contain 13 protein-coding genes (PCGs), 2 ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes and two non-coding regions. All PCGs are initiated by ATG codons, except for the cytochrome coxidase subunit 1 (cox1) gene. All of the tRNA genes could be folded into typical cloverleaf secondary structures, with the exception of tRNASer(AGN) lacks a dihydrouracil (DHU) stem. The control regions are both 838 bp and contain several features common to Scorpaeniformes. The phylogenetic relationships of 33 fish mitogenomes using Bayesian Inference (BI) and Maximum Likelihood (ML) based on nucleotide and amino acid sequences of 13 PCGs indicated that the mitogenome sequences could be useful in resolving higher-level relationship of Scorpaeniformes. The results may provide more insight into the mitogenome evolution of teleostean species.

Background The freshwater fish Gobiobotia naktongensis (Teleostei, Cypriniformes, and Gobionidae) is an endangered class I species whose population size has been greatly reduced. Objective To successfully protect and restore the highly endangered freshwater fish G. naktongensis from the Geum River in South Korea. Methods The mitogenome was characterized using the primer walking method with phylogenetic relationships. Results The complete mitogenome of G. naktongensis Geum River was 16,607 bp, comprising 13 protein-coding genes, 2 ribosomal RNA genes, and 22 transfer RNA (tRNA) genes. Seventeen substitutions were found by comparing the tRNA regions between G. naktongensis Geum and Nakdong Rivers and G. pappenheimi; most were specific to G. naktongensis Nakdong River, with changes in their secondary structures. The comparison between G. naktongensis Geum River and G. pappenheimi revealed differences in the lengths of the D-loop and two tRNAs (tRNAArg and tRNATrp) and the secondary structures in the TΨC-arm of tRNAHis. In the phylogenetic tree, G. naktongensis Geum River did not cluster with its conspecific specimen from the Nakdong River in South Korea, but showed the closest relationship to G. pappenheimi in mainland China. Conclusions Our results support the existence of the Paleo-Huanghe River connecting the Korean peninsula and mainland China, suggesting that G. naktongensis in the Geum River should be treated as a different evolutionarily significant unit separated from that in the Nakdong River. The complete mitogenome of G. naktongensis Geum River provides essential baseline data to establish strategies for its conservation and restoration.
