Complete mitochondrial genome of freshwater goby Rhinogobius cliffordpopei (Perciformes, Gobiidae): genome characterization and phylogenetic analysis

Characterization of the complete mitochondrial genome of Rhinogobius leavelli (Perciformes: Gobiidae: Gobionellinae) and its phylogenetic analysis for Gobionellinae

“…The NJ and ML analysis showed similar phylogenetic trees and both presented five major clades, which was in accordance with previous molecular study (Agorreta et al 2013;Xia et al 2015;Gong et al 2017;Zhong et al 2018). The major different between NJ and ML phylogenetic trees was relationship between genus Rhinogobius and genus Tridentiger.…”

“…Conventional stop codons (TAA and TAG) had been found in seven PCGs, while two kinds of incomplete stop codons (Tand TA-) were found in the remaining six PCGs, which could be completed by post-transcriptional polyadenylation (Ojala et al 1981). The location and structure of tRNA genes of R. leavelli were similar to R. cliffordpopei (Nichols, 1925) (Zhong et al 2018) and were conservative like other bony fish. Non-coding regions were assumed to act as splicing recognition sites during the process of transcription (He et al 2005).…”

“…The non-coding regions in the R. leavelli mitogenome ranged from 1 to 846 bp and the largest spacer, Dloop usually causes length change of the whole mitogenome. In R. cliffordpopei, a putative stable stem-loop secondary structureof its second largest spacer was inferred (Zhong et al 2018), which was thought to play an importance role inconjunction with the origin of mitochondrial DNA replication (Desjardins and Morais 1990). The second largest spacer was 31 bp in length and located between tRNA-Asn and tRNA-Cys genes, which was similar to R. cliffordpopei and maybe also play an importance role in R. leavelli.…”

Characterization and phylogenetic analysis of the complete mitochondrial genome of Rhinogobius sp. (Perciformes, Gobiidae)

“…was determined using 12 pairs of primers which were designed based on the mitogenome sequence of Rhinogobius clifordpopei (Zhong et al. 2018 ).…”

The mitochondrial genome of striped snakehead Channa striata (Perciformes: Channidae) and phylogenetic analysis

“…The complete mitochondrial genome of C. striata was 16,531 bp in length, which composed of 13 protein-coding genes (PCG), 22 tRNA, 2 rRNA genes and one control region. All the genes of C. striata encoded on the H-strand with the exception of one PCG (ND6) and 8 tRNAs (tRNA-Gln, tRNA-Ala, tRNA-Asn, tRNA-Cys, tRNA-Tyr, tRNA-Ser(UCN), tRNA-Pro, and tRNA-Glu), which was typical for teleost mtDNA (Zhong et al 2018). The typical ATG start codons were present in PCGs except for COI with GTG, and three types of stop codons (TAA, TA-, and T-) were found, and the incomplete stop codons were presumably completed by posttranscriptional polyadenylation (Ojala et al 1981).…”
