Complete mitochondrial genome sequences and phylogenetic relationship of Elysia ornata (Swainson, 1840) (Mollusca, Gastropoda, Heterobranchia, Sacoglossa)

Abstract The sacoglossans are small sea slugs in the Heterobranchia. In this study, mitochondrial genome of a sacoglossan sea slug, Elysia ornata (Swainson, 1840) is analyzed and phylogenetic tree of the species in the Heterobranchia is reconstructed based on amino acid sequences of mitochondrial protein coding genes. The phylogenetic relationship analysis shows that E. ornata belongs to the monophyletic Sacoglossa in the Heterobranchia and the Sacoglossa shows sister group relationship with a lineage including Anaspidea and Siphonarioidea. This is the fourth record for the mitochondrial genome of sacoglossan sea slugs.

Complete mitochondrial genome of Leptodius sanguineus (Decapoda, Xanthidae)

Abstract The complete mitochondrial genome sequenced from a xanthid crab, Leptodius sanguineus which was collected from a rocky intertidal area in Chuuk lagoon. The mitochondrial genome size of L. sanguineus evaluated as 15,480 bp with 33.6% A, 24% C, 11.2% G and 31.2% T and mitochondrial gene order of L. sanguineus is typical to brachyuran species. Phylogenetic analysis shows that the family Xanthidae has sister group relationship with a lineage including the families Portunidae and Menippidae in the subsection Heterotremata. This is the first report for the complete mitochondrial genome from the xanthid crabs.

Abstract Complete mitochondrial genome of smooth-handed ghost crab Ocypode cordimanus (Latreille, 1818) has been sequenced and phylogenetic relationships evaluated due to mitochondrial protein coding genes. This is the second record of complete mitochondrial genome from the genus. The size of mitochondrial genome for O. cordimanus is 15,604 bp and the nucleotide distribution of the mitochondrial genome is 31.8% A, 21.8% C, 11.9% G and 34.5% T.

Complete mitochondrial genome of Atergatis integerrimus (Decapoda, Xanthidae) from the Philippines

Abstract In this study, a complete mitochondrial genome from the red egg crab, Atergatis integerrimus was sequenced and analyzed. The mitochondrial genome length is 16,333 bp and is composed of 13 protein-coding, two ribosomal RNA and 22 tRNA genes. The structure and gene orientation of the mitochondrial genome was found to be identical with the other brachyurans. The position of A. intergerrimus in the superfamily Xanthoidea was determined based on the mitochondrial protein-coding genes. The result of the phylogenetic relationship study showed that A. integerrimus was closest to Leptodius sanguineus.

Complete mitochondrial genome analysis of Phascolosoma sp. (Sipuncula, Phascolosomatida, Phascolosomatidea) from Micronesia

Abstract In this study a Sipuncula species Phascolosoma sp. was collected from seagrass area from Chuuk lagoon Micronesia and its complete mitochondrial genome analyzed. This is the second complete mitochondrial genome record from the genus after Phascolosoma esculenta. The total length of mitochondrial genome of the species is 16,571 bp, which is longer than P. esculenta record. Also, locations of tRNA-Gly and putative control region are different between two records. Furthermore, phylogenetic relationship of Phascolosoma sp. are investigated due to protein-coding genes of mitochondrial genome. Due to the lack of recorded data, P. esculenta has been observed is the closest species to Phascolosoma sp. and they are belonging to the monophyletic group.

The complete mitochondrial genome of Menathais tuberosa (Gastropoda, Neogastropoda, Muricidae) collected from Chuuk Lagoon

Abstract Complete mitochondrial genome of the knobbed rock shell sea snail Menathais tuberosa (Röding, 1798) has been sequenced and phylogenetic relationships evaluated due to mitochondrial protein coding genes. The size of mitochondrial genome for M. tuberosa is 15,294 bp and the nucleotide composition of the mitochondrial genome is 28.4% A, 16.5% C, 17.6% G and 37.5% T. Reconstructed phylogenetic tree of the Neogastropoda showed that M. tuberosa is in the monophyletic Muricidae. This is the first record of complete mitochondrial genome from the genus.

Complete mitochondrial genome of xanthid crab Atergatis floridus (Linnaeus, 1767)

Abstract The complete mitochondrial genome sequenced from the floral egg crab Atergatis floridus (Linnaeus, 1767) and the determination of the position of the species in the reconstructed phylogenetic tree of the infraorder Brachyura using the protein coding mitochondrial genes are presented. Results show the mitochondrial genome length of A. floridus is 16,435 bp with nucleotide distribution as 33.4% A, 20.3% C, 10.5% G and 35.8% T. The structure of the complete mitochondrial genome of the species is the same as with the previous xanthid record. The result of the phylogenetic analysis suggests that A. floridus is the closest species to other Xanthidae species in the brachyuran records. This is the first complete mitochondrial genome record from the genus Atergatis.

Analysis of complete mitochondrial genome of Etisus anaglyptus (Arthropoda, Decapoda, Xanthidae) with phylogenetic consideration

Abstract The complete mitochondrial genome is sequenced and analyzed from a xanthid crab Etisus anaglyptus, which is the first complete mitochondrial genome for the genus. The mitochondrial genome length of E. anaglyptus is 16,435 bp and it is composed of 13 protein coding genes, two ribosomal RNA genes, and 22 tRNA genes. The structure and gene orientation of the mitochondrial genome is identical with the other brachyuran records. Furthermore, phylogenetic relationships of the infraorder Brachyura evaluated by mitochondrial protein coding genes. The phylogenetic study showed that E. anaglyptus is positioned in the superfamily Xanthoidea and the closest species to E. anaglyptus is Leptodius sanguineus.

The complete mitogenome of ghost jellyfish Cyanea nozakii (Cnidaria, Semaeostomeae, Cyaneidae)

Abstract The cnidarian jellyfishes are impressive organisms to show animal mitochondrial genomic diversities. Their mitogenome structure is linear and tRNA content has one or two in numbers, which is highly different than other metazoans. In this study, a complete mitogenome of the ghost jellyfish Cyanea nozakii (Cnidaria, Semaeostomeae, Cyaneidae) was sequenced and analyzed. The mitgenome is 17,381 bp long with 38.5% A, 16.0% C, 13.9% G, and 31.6% T nucleotide distributions. In addition, phylogenetic relationship of C. nozakii in the class Scyphozoa was investigated by using mitochondrial protein coding genes. Due to results, C. nozakii was positioned in the paraphyletic order Semaeostomeae. This is the first complete mitogenome from the genus Cyanea.

The complete mitochondrial genome of Hemigrapsus penicillatus (De Haan, 1835) (Decapoda, Varunidae)

Abstract Hemigrapsus penicillatus is a small grapsoid crab which is found in Japan, Taiwan, Korea, and China coasts. In this study a complete mitogenome of Korean H. penicillatus was analyzed and phylogenetic relationships in the family Varunidae were investigated. The mitogenome size is 16,486 bp with 34.1% A, 18.1% C, 11.4% G, and 36.4% T nucleotide distributions. Genome structure and gene orientations are identical with previous records from the family and mitochondrial protein-coding gene based phylogenetic tree suggested that the closest species to H. penicillatus is H. sanguineus. This is the second complete mitogenome record from the genus Hemigrapsus and the first record for the species.
