Characterization and phylogenetic analysis of the complete mitochondrial genome of Stephnometra indica (Pelmatozoa: Crinoidea).

ABSTRACT: The crinoid Stephnometra indica inhabits coral reefs and surrounding waters in the western Pacific Ocean. In this study, the complete mitochondrial genome of S. indica (15,878?bp) was confirmed to contain 13 protein-coding genes, 22 tRNA genes, and 2 rRNA genes. The gene order of S. indica was identical to that of previously published Crinoidea. The nucleotide composition of the S. indica mitogenome was biased toward A?+?T nucleotide 73.68%. There were four unassigned regions (UASs) found in S. indica and all four UAS regions were AT-biased. The phylogenetic relationship illustrated that S. indica is more closely related to Antedon mediterranea within the family Crinoidea.

The complete mitochondrial genome of Anneissia intermedia (Crinoidea: Comatulida: Comatulidae).

Project description:Anneissia intermedia (A.H. Clark, 1916) is a common crinoid found in waters along the coastlines of China, Japan, and Korea. In this study, we determined the complete mitogenome of A. intermedia. The genome was found to be 15,874 bp in length and consists of 13 protein-coding genes, 22 tRNAs, and 2 rRNAs. With the exception of Antedon mediterranea, the gene order and genetic characteristics of the A. intermedia mitogenome are identical with those of the mitogenomes of other crinoids. The complete mitogenome of A. intermedia will contribute to enhance our understanding of the phylogeny of crinoids.

Characterization and phylogenetic analysis of the complete mitochondrial genome sequence of Photinia serratifolia.

Project description:Plant mitochondrial genomes (mitogenomes) are a valuable source of genetic information for a better understanding of phylogenetic relationships. However, no mitogenome of any species in the genus of Photinia has been reported. In this study, using NGS sequencing, we reported the mitogenome assembly and annotation of Photinia serratifolia, which is 473,579 bp in length, contains 38 protein-coding genes, 23 tRNAs, and 6 rRNAs, with 61 genes have no introns. The rps2 and rps11 genes are missing in the P. serratifolia mitogenome. Although there are more editing sites (488) in the P. serratifolia mitogenome than in most angiosperms, fewer editing types were found in the P. serratifolia mitogenome, showing a clear bias in RNA-editing. Phylogenetic analysis based on the mitogenomes of P. serratifolia and 8 other taxa of the Rosaceae family reflected the exact evolutionary and taxonomic status of P. serratifolia. However, Ka/Ks analysis revealed that 72.69% of the protein-coding genes in the P. serratifolia mitogenome had undergone negative selections, reflecting the importance of those genes in the P. serratifolia mitogenome. Collectively, these results will provide valuable information for the evolution of P. serratifolia and provide insight into the evolutionary relationships within Photinia and the Rosaceae family.

Complete mitochondrial genome of Rhodeuscyanorostris (Teleostei, Cyprinidae): characterization and phylogenetic analysis.

Project description:Rhodeuscyanorostris Li, Liao & Arai, 2020 is a freshwater fish that is endemic to China and restricted to Chengdu City in Sichuan Province. This study is the first to sequence and characterize the complete mitochondrial genome of R.cyanorostris. The mitogenome of R.cyanorostris is 16580 bp in length, including 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and a control region (D-loop). The base composition of the sequence is 28.5% A, 27.6% C, 26.4% T, and 17.5% G, with a bias toward A+T. The genome structure, nucleotide composition, and codon usage of the mitogenome of R.cyanorostris are consistent with those of other species of Rhodeus. To verify the molecular phylogeny of the genus Rhodeus, we provide new insights to better understand the taxonomic status of R.cyanorostris. The phylogenetic trees present four major clades based on 19 mitogenomic sequences from 16 Rhodeus species. Rhodeuscyanorostris exhibits the closest phylogenetic relationship with R.pseudosericeus, R.amarus, and R.sericeus. This study discloses the complete mitochondrial genome sequence of R.cyanorostris for the first time and provides the most comprehensive phylogenetic reconstruction of the genus Rhodeus based on whole mitochondrial genome sequences. The information obtained in this study will provide new insights for conservation, phylogenetic analysis, and evolutionary biology research.

Complete mitochondrial genome of the crinoid echinoderm, Florometra species (Echinodermata, Crinoidea).

Project description:In this study, we report the sequence of the mitochondrial genome (mitogenome) of the crinoid echinoderm, Florometra species (Echinodermata, Crinoidea). The complete mitogenome of Florometra sp. was 15,792 base pairs long and was composed of 13 protein-coding genes (PCGs), two ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes, and three regions of unassigned sequence (UAS) including one putative control region. Unique nucleotide composition, a clear positive bias for T with an apparent loss of C in PCGs as observed in the Crinoidea mitogenomes, was also seen in the Florometra sp. mitogenome (45% T, 12% C). Phylogenetic analysis with the concatenated nucleotide sequences of entire PCGs of echinoderms confirmed that Florometra sp. is highly related to F. serratissima within the family Crinoidea.

The complete mitochondrial genome of Wellcomia compar (Spirurina: Oxyuridae) and its genome characterization and phylogenetic analysis.

Project description:Wellcomia compar (Spirurina: Oxyuridae) is a pinworm that infects wild and captive porcupines. Despite clear records of its morphological structure, its genetics, systematics, and biology are poorly understood. This study aimed to determine the complete mitochondrial (mt) genome of W. compar and reconstruct its phylogenetic relationship with other nematodes. We sequenced the complete mt genome of W. comparand conducted phylogenetic analyses using concatenated coding sequences of 12 protein-coding genes (PCGs) by maximum likelihood and Bayesian inference. The complete mt genome is 14,373 bp in size and comprises 36 genes, including 12 protein-coding, two rRNA and 22 tRNA genes. Apart from 28 intergenic regions, one non-coding region and one overlapping region also occur. A comparison of the gene arrangements of Oxyuridomorpha revealed relatively similar features in W. compar and Wellcomia siamensis. Phylogenetic analysis also showed that W. compar and W. siamensis formed a sister group. In Oxyuridomorpha the genetic distance between W. compar and W. siamensis was 0.0805. This study reports, for the first time, the complete W. compar mt genome sequence obtained from Chinese porcupines. It provides genetic markers for investigating the taxonomy, population genetics, and phylogenetics of pinworms from different hosts and has implications for the diagnosis, prevention, and control of parasitic diseases in porcupines and other animals.
