This paper reports four new species of the primitively segmented spider genus Songthela from Chongqing Municipality, China, based on morphological characters of both males and females: S. jinyun sp. nov., S. longbao sp. nov., S. serriformis sp. nov. and S. wangerbao sp. nov. We also provide the GenBank accession codes of mitochondrial DNA barcode gene, cytochrome c oxidase subunit I (COI), for the holotype of four new species for future identification.

En este estudio se analizan dos fragmentos del gen de la citocromo c oxidasa subunidad I (COX1) del ADN mitocondrial de 61 individuos del género Rhynchophorus colectados en la Región de Murcia a fin de determinar su procedencia. El análisis filogenético del fragmento 1 de las muestras de la Región de Murcia conjuntamente con las secuencias disponibles en GenBank indica que los individuos corresponden a la especie Rhynchophorus ferrugineus.Las secuencias de Murcia se colapsan en un único haplotipo (H8 mediterráneo) que aparece dentro del clado de R. ferrugineus. De los análisis filogeográficos se infiere que el origen de los individuos de Murcia es Egipto. Adicionalmente, se examinó una región contigua del COX1 (fragmento 2) en la que las secuencias se colapsaron en dos haplotipos. In this research two fragments of the cytochrome c oxidase subunit I (COX1) gene of the mitochondrial DNA were analyzed in 61 individuals of the genus Rhynchophorus collected in the Region of Murcia with the aim of determining their origin. Phylogenetic analysis of fragment 1 of the samples collected in the Region of Murcia together with the available sequences in GenBank, indicated that these individuals correspond to the species R. ferrugineus. Sequences from Murcia collapsed into the H8 Mediterranean haplotype, which cluster into the R. ferrugineus clade. Phylogeographic analysis shows that the origin of the individuals collected in the Region of Murcia is Egypt. Additionally, a contiguous fragment of COX1 (fragment 2) was analyzed and the sequences collapsed into two haplotypes.

AbstractThe nucleotide sequences of partial 18S, complete internal transcribed spacer region 1 (ITS1), complete 5.8S, complete ITS2 and partial 28S of ribosomal DNA (rDNA) and cytochrome c oxidase subunit 1 of mitochondrial DNA (MCOI) from five species of gnathostomes (G. spinigerum, G. doloresi, G. nipponicum, G. hispidum and G. binucleatum with the former four species being distributed in Japan and Asia) that cause human gnathostomiasis were compared by direct polymerase chain reaction cycle-sequencing. The nucleotide sequences of each region of the18S (613 bp), 5.8S (158 bp) and 28S (598 bp) rDNA from the five species were almost identical. The ITS1 region was different in length for the five species. The nucleotide sequences of each region of ITS2 and partial MCO1 regions were different among the five species. Therefore, these two regions can be used as genetic markers for identification of worms.

The potential of mitochondrial DNA (mtDNA) genes are well-known for species identification and to establish a phylogenetic relationship. The De-novo transcriptome assembly of Acheta domesticus commonly known as house cricket, is provides important segments of DNA fragments from mitochondrial DNA due to higher abundance of its mRNA. When the reference sequence with gene annotation is absent for assembling and aligning desire gene sequences, like in the present case, the most similar sequence is obtained from online insect mitochondrial genome database to find mitochondrial DNA conserved domains of interested gene from high throughput RNA sequencing (RNA-seq) data. The RNA-seq data of Acheta domesticus transcriptome is used to retrieve single nucleotide fragment out of 50,046 assembled contigs to discover three important genes from mtDNA of the house cricket. Present study provides effective workflow to identify genes like cytochrome c oxidase subunit II (COX2), NADH dehydrogenase subunit 2 (ND2), cytochrome c oxidase subunit I (COX1) from mtDNA in large sequence archive of RNA-seq data. These three novel barcode sequences will be useful for genetic identification and evolution investigation of Acheta domesticus. The partial mtDNA sequence with these genes will be important for mitochondrial genome construction.

We identified a polyadenylated RNA species which contains the origin of human mitochondrial DNA light-strand synthesis and the surrounding complementary sequences of the four light-strand-encoded tRNAs. This RNA (RNA 9L) is probably derived from the leader portion of RNA 6 which is excised during the formation of the mature cytochrome c oxidase subunit mRNA (RNA 9). The high degree of secondary structure of this RNA is presumably responsible for its anomalous electrophoretic behavior in denaturing polyacrylamide gels.
