The Eisenia nordenskioldi (Eisen, 1879) species complex is one of the most widely distributed earthworm taxa in northern Asia, owing to its high morphological and genetic variability. This complex is ...represented by smaller, slightly pigmented- or unpigmented specimens in the Korean Peninsula. Here, we report the mitogenomes of two Eisenia nordenskioldi cf. pallida specimens, No. 1 and No. 3, which are slightly pigmented and unpigmented, respectively. The total length of the mitogenomes was 15,824 bp and 15,177 bp, respectively, and contained 37 genes, comprising 13 protein-coding genes (PCGs), two rRNA genes, 22 tRNA genes, and a putative non-coding region, as in other earthworms. Nucleotide sequence comparisons of the 37 genes and the predicted protein sequences of 13 PCGs showed 96.6 % and 98.6 % similarity between the two mitogenomes, respectively. A phylogenetic analysis of 33 Crassiclitellata mitogenomes corroborated the monophyly of the Eisenia genus and recovered two highly supported subclades in the E. nordenskioldi species complex. The Korean specimens were the closest to the E. n. pallida L2 specimens collected near the type locality and probably represent the genuine E. nordenskioldi pallida Malevich, 1956.
The study of Hemipteran mitochondrial genomes (mitogenomes) began with the Chagas disease vector, Triatoma dimidiata, in 2001. At present, 90 complete Hemipteran mitogenomes have been sequenced and ...annotated. This review examines the history of Hemipteran mitogenomes research and summarizes the main features of them including genome organization, nucleotide composition, protein-coding genes, tRNAs and rRNAs, and non-coding regions. Special attention is given to the comparative analysis of repeat regions. Gene rearrangements are an additional data type for a few families, and most mitogenomes are arranged in the same order to the proposed ancestral insect. We also discuss and provide insights on the phylogenetic analyses of a variety of taxonomic levels. This review is expected to further expand our understanding of research in this field and serve as a valuable reference resource.
El lenguado de California, Paralichthys californicus, es una especie de pez plano con un alto valor econónico debido a su tamaño y a la calidad de su carne. En este trabajo se presenta el genoma ...mitocondrial completo de P. californicus. Se extrajo ADN total de tejido muscular y se secuenció utilizando la plataforma Illumina. Las lecturas obtenidas se limpiaron, se recortaron, se ensamblaron de novo y se anotaron. El mitogenoma del lenguado de California tiene una logitud de 16,858 pb (número de acceso del GenBank: MT859134) y contiene 13 genes codificadores de proteínas, 22 ARNt, 2 ARNr y la región control. El mitogenoma de P. californicus fue más similar al de Paralichthys olivaceus que a mitogenomas de otros peces planos, en concordancia con su distribución geográfica. La información aquí presentada incrementa el conocimiento del lenguado de California, el cual no solo es una especie de importancia económica, sino también un recurso socioeconómico relevante para la pesquería y la acuicultura de California, EUA, y de Baja California, México.
DNA was extracted from a red algal herbarium specimen collected in 1920 and subjected to next generation sequencing. Here we report the assembly of the mitogenome of a marine mussel, Mytilus ...trossulus, deciphered from this plant museum specimen. The mitogenome is 16,744 bp in length, contains 38 genes, and is more similar to other M. trossulus reported from the Baltic Sea. The data show that in addition to plant DNA, herbarium specimens also contain genetic information from invertebrates that may be valuable for genomic, population and phylogenetic studies of animals.
