The mitochondrial genome of a 9-arm feather star Thaumatocrinus naresi (Crinoidea, Pentametrocrinidae).

ABSTRACT: The genus Thaumatocrinus is composed of species displaying 10 undivided arms arising from 10 radials. Thaumatocrinus naresi is also considered to be a 10-arm species, but individuals with 9 arms were also reported. Here, we report the mitochondrial genome of T. naresi with 9 arms collected from the western Pacific. The genome is 16,047 bp in length with a 67.84% AT content. It contains 13 protein-coding genes (PCGs), 2 ribosomal RNA genes, and 22 transfer RNA genes. Phylogenetic analysis shows that T. naresi forms an independent lineage within Comatulida.

The complete mitochondrial genome of Comaster schlegelii (Crinoidea, Comatulida).

Project description:Comaster schlegelii, belonging to the family Comatulidae, is a variable feather star distributed in the Pacific Ocean. The complete mitochondrial genome of this species was 15,887 bp in length, consisting of 13 protein-coding genes, 22 transport RNA genes, two ribosomal RNA genes and one control region. The whole mitochondrial genome of C. schlegelii had a high AT content of 72.73%. The phylogenetic relationship was reconstructed with 16 relevant echinoderms, which revealed C. schlegelii was closely clustered with Anneissia pinguis in the family Comatulidae.

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.

Complete mitochondrial genome of the crinoid Poliometra prolixa (Crinoidea: Comatulida: Antedonidae).

Project description:Poliometra prolixa Sladen, 1881, is a comatulid crinoid found in the Arctic deep sea. In this study, we report the complete mitochondrial genome sequence of P. prolixa (Comatulida: Antedonidae). The complete mitogenome of P. prolixa was 15,916 bp long and comprised 13 protein-coding genes (PCGs), 22 transfer RNA genes, and 2 ribosomal RNA genes. The base composition of the P. prolixa mitogenome was 24.0% A, 44.9% T, 19.0% G, and 12.1% C. Phylogenetic analysis using all PCGs of the complete mitogenome confirmed the inclusion of P. prolixa within the Comatulida.

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.

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

Project description: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.

Retinoic Acid Signaling Regulates the Metamorphosis of Feather Stars (Crinoidea, Echinodermata): Insight into the Evolution of the Animal Life Cycle.

Project description:Many marine invertebrates have a life cycle with planktonic larvae, although the evolution of this type of life cycle remains enigmatic. We recently proposed that the regulatory mechanism of life cycle transition is conserved between jellyfish (Cnidaria) and starfish (Echinoderm); retinoic acid (RA) signaling regulates strobilation and metamorphosis, respectively. However, the function of RA signaling in other animal groups is poorly understood in this context. Here, to determine the ancestral function of RA signaling in echinoderms, we investigated the role of RA signaling during the metamorphosis of the feather star, Antedon serrata (Crinoidea, Echinodermata). Although feather stars have different larval forms from starfish, we found that exogenous RA treatment on doliolaria larvae induced metamorphosis, like in starfish. Furthermore, blocking RA synthesis or binding to the RA receptor suppressed metamorphosis. These results suggested that RA signaling functions as a regulator of metamorphosis in the ancestor of echinoderms. Our data provides insight into the evolution of the animal life cycle from the viewpoint of RA signaling.

The skeletal proteome of the feather star Anneissia japonica

Project description:Skeletal elements from the feather star Anneissia japonica were isolated and stripped of organic material. The skeleton was then demineralized and the occluded proteins isolated. The proteins were separated by SDS-PAGE and fractions were analyzed by LC-MS/MS. The results were compared to predicted proteins encoded by the genome. The proteins found in the organic matrix of the skeleton were compared to those found in other skeletons both within Echinodermata and to other taxa.
