The complete mitochondrial genome and phylogenetic analysis of the dwarf surf clam Mulinia lateralis.

ABSTRACT: Mulinia lateralis (Say, 1822) is a species of the bivalve family Mactridae and represents a promising model species for molluscan research. In this study, the complete mitochondrial genome (mitogenome) of M. lateralis was sequenced and assembled for the first time. The 21,668?bp mitogenome contained 13 protein-coding genes, 2 rRNAs, 22 tRNA genes, and an AT-rich region. The overall AT content (69.56%) was higher than GC content (30.44%). Phylogenetic analysis supported that M. lateralis belongs to the family Mactridae. The mitochondrial genome of M. lateralis provides a valuable resource for further understanding the phylogeny of the family Mactridae and for functional studies of molluscan mitochondrial genes.

The complete mitochondrial genome sequence and phylogenetic analysis of Luciola lateralis, one of the most famous firefly in Japan (Coleoptera: Lampyridae).

Project description:We will report the complete mitochondrial genome sequence of Japanese firefly 'Heike Botaru', Luciola lateralis (Coleoptera: Lampyridae). Total length of this mitogenome was 16,719?bp and the composition of each base was A (42.50%), C (9.01%), G (14.16%), T (34.33%), respectively. The obtained sequence fulfils general mitogenome composition of metazoan (13 protein coding sequences (CDSs), 22 tRNA genes, two rRNA subunits, and an AT-rich region). From the phylogenetic tree analysis using 25 kinds of insect mitogenome including firefly family was found that L. lateralis is the closest to the genus Aquatica.

Complete mitochondrial genome of the soft-shell clam Mya arenaria.

Project description:We have sequenced and characterized the complete mitochondrial genome of the soft-shell clam, Mya arenaria, an important organism for environmental toxicology and aquaculture. Mya arenaria is located in the taxonomic order Myoida, which lacks any member with a completely annotated mitogenome. The M. arenaria mitochondrial genome is 17?947?bp in length. Like most marine bivalves, the circular mitogenome codes entirely on the heavy strand, with no introns. As with other bivalves, the gene order of the mitochondrion is highly rearranged. The mitogenome contains 12 protein-coding genes but ATP8 is missing, consistent with about half of all bivalve genera. Twenty-three tRNAs were identified. Phylogenetic analysis shows that M. arenaria is related most closely with the bivalves Sinonovacula constricta, and Moerella iridescens, of the infraclass Euheterodonta (unassigned). This, along with the close grouping of the phylogenetic trees, confirms a close tie between Myoida and Euheterodonta (unassigned).

Centrosome-associated RNA in surf clam oocytes.

Project description:Centrosomes are the major microtubule-organizing center in animal cells. They are composed of a pair of [9(3) + 0] centrioles surrounded by a relatively ill-defined pericentriolar matrix, provide the ciliary centriole-kinetosome (basal body) progenitor, and organize the assembly of microtubules into the mitotic spindle during cell division. Despite >100 years of microscopic observation and their obvious significance, our understanding of centrosome composition, dynamic organization, and mechanism of action is limited when compared with that of other cellular organelles. Centrosomes duplicate only once per cell cycle to ensure development of a normal bipolar spindle. The initial event in centrosome duplication is centriole replication, which is generative, semiconservative, and independent of the nucleus. Such observations led to the proposal that centrosomes contain their own complement of nucleic acids, possibly representative of an organellar genome comparable with those described for mitochondria and chloroplasts. The consensus in the field is that centrosomes lack DNA but may contain RNA. We isolated centrosomes from oocytes of the surf clam, Spisula solidissima, and purified from them a unique set of RNAs. We show here by biochemical means and subcellular in situ hybridization that the first transcript we analyzed is intimately associated with centrosomes. Sequence analysis reveals that this centrosome-associated RNA encodes a conserved RNA-directed polymerase domain. The hypothesis that centrosomes contain an intrinsic complement of specific RNAs suggests new opportunities to address the century-old problem of centrosome function, heredity, and evolution.

Complete mitochondrial genome of the surf smelt Hypomesus japonicus (Osmeriformes, Osmeridae).

Project description:The complete mitochondrial genome was sequenced in two individuals of the surf smelt Hypomesus japonicus. The genome sequences are 16,762 and 16,771?bp in size, and the gene arrangement, composition, and size are very similar to the other smelt mitochondrial genomes published previously. The difference between two H. japonicus genomes studied is 0.37%, which is noticeably higher in comparison with other osmerid fishes. The level of sequence divergence between H. japonicus and related osmerids belonging to genera Hypomeus, Osmerus, and Mallotus varies within a very narrow range (12.31-13.72%) indicating poor phylogenetic resolution of this complex fish group.

Complete mitochondrial genome of the hard clam (Mercenaria mercenaria).

Project description:The hard clam (Mercenaria mercenaria) is an important economic and ecological bivalve. In this study, the mitochondrial genome was sequenced. The sequenced genome size was 18,360 bp. The nucleotide composition was asymmetric with a AT bias. Mitogenome contained 13 protein-coding genes (PCGs), 2 rRNA genes, and 22 tRNA genes. Of 13 PCGs, 3 genes (cox3, nad3, and cox2) had incomplete stop codons. Furthermore, phylogenetic analysis using 12 PCGs (except atp8) figured out that M. mercenaria was closely related to genus Dosinia. The complete mitogenome of M. mercenaria provides essential information for further phylogenetic and evolutionary analysis in Veneridae.

Project description:The complete nucleotide sequence of the mitochondrial genome (mitogenome) of Aspiorhynchus laticeps was determined. The length of the complete mitochondrial DNA sequence of A. laticeps is 16,591 bp, which consists of 13 protein-coding genes, 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a non-coding region 'D-loop'. Except for the D-loop, another non-coding region named replication origin of L-strand (OL) region was also found. According to the phylogenetic analysis, A. laticeps has a closer relationship with Schizothorax.

Project description:Ixodes persulcatus is a species of hard tick which is a predominant tick species that spreads a wide array of serious human and animal pathogens. Here, we first assemble the complete mitogenome of I. persulcatus of China. The total length of the mitogenome was 14,539 bp included 36 genes and with a mitogenome structure similar to other ticks. Phylogenetic tree was constructed based on the complete mitogenome of I. persulcatus and closely related 19 species ticks to assess their phylogenic relationship and evolution. We also analyze the differences between the mitogenomes of I. persulcatus of Japan and China. The complete mitogenome data would be useful for further study of I. persulcatus.

The complete mitochondrial genome of Min pig (Hebao) and a phylogenetic analysis.

Project description:The complete mitochondrial genomes of Min pig (Hebao) are published in this paper. The full length of mtDNA is 16,719?bp and contained 13 PCGs, 2 rRNA and 22 tRNA, and 1D-loop(MN258706). A phylogenetic tree with the 13 protein-coding genes sequences of Min pig (Hebao) together with 45 other Chinese pig breeds and 7 foreign pig breeds was constructed. The results can be subsequently used to provide information for pig phylogenetic and insights into the evolution of genomes. The result of phylogenetic analysis showed that the genetic relationship of Min pig (Hebao) is closer to that of Dapulian pigs.
