1. The complete chloroplast genome sequence of Vincetoxicum mongolicum (Apocynaceae), a perennial medicinal herb
Abstract Vincetoxicum mongolicum Maxim. (1876), is a perennial medicinal herb, widely distributed in the Loess Plateau of China. Here, we sequenced, assembled, and annotated the complete chloroplast (cp) genome of V. mongolicum, and compared the highly variable gene regions and phylogenetic positions between V. mongolicum and other related species. Results s

2. Araucaria angustifolia chloroplast genome sequence and its relation to other Araucariaceae
Abstract Araucaria angustifolia is endemic to southern Brazil. Known as Brazilian pine, A. angustifolia is the only native conifer species with economic and social relevance in this country. Due to massive exploitation, it has suffered a significant population decline and currently is classified as critically endangered. This encouraged the scientific commun

3. Analysis of tRNA halves (tsRNAs) in serum from cattle challenged with bovine viral diarrhea virus
Abstract Acute infections of bovine viral diarrhea virus (BVDV) lead to a range of clinical presentations. Laboratory tests for detection depend on collection of samples during a short viremia. Acutely infected animals remain largely undiagnosed. Transfer RNA halves (tsRNAs) are hypothesized to function like microRNAs to regulate gene expression during an im

4. [PROVISIONAL] Mitochondrial genomes of genus Atta (Formicidae: Myrmicinae) reveal high gene organization and giant intergenic spacers
Abstract The ants of the genus Atta are considered an important pest to agriculture in Latin América, although, Atta species are important contributors to ecosystem functions in the various habitats in which they occur. Next-generation sequencing product millions or billions of short reads, however, is necessary to applied methods for assembly of the genome

5. Mycobacterium genus and tRNA arrays
The presence of tRNA array, a region with high tRNA gene number and density, has been demonstrated in Mycobacterium genus. However, a recent phylogenomic study revealed the existence of five distinct monophyletic groups (genera) within this genus. Considering this new scenario, and based on in-silico analyses, we have identified and characterised the abundan

6. Exploring tRNA gene cluster in archaea
BACKGROUND Shared traits between prokaryotes and eukaryotes are helpful in the understanding of the tree of life evolution. In bacteria and eukaryotes, it has been shown a particular organisation of tRNA genes as clusters, but this trait has not been explored in the archaea domain. OBJECTIVE Explore the occurrence of tRNA gene clusters in archaea. METHO

7. Complete sequence and comparative analysis of the chloroplast genome of Plinia trunciflora
Abstract Plinia trunciflora is a Brazilian native fruit tree from the Myrtaceae family, also known as jaboticaba. This species has great potential by its fruit production. Due to the high content of essential oils in their leaves and of anthocyanins in the fruits, there is also an increasing interest by the pharmaceutical industry. Nevertheless, there are fe

8. The complete mitochondrial genome of Engyodontium album and comparative analyses with Ascomycota mitogenomes
Abstract Engyodontium album is a widespread pathogen that causes different kinds of dermatoses and respiratory tract diseases in humans and animals. In spite of its perniciousness, the basic genetic and molecular background of this species remains poorly understood. In this study, the mitochondrial genome sequence of E. album was determined using a high-thro

9. Complete mitochondrial genome of the lappet moth, Kunugia undans (Lepidoptera: Lasiocampidae): genomic comparisons among macroheteroceran superfamilies
Abstract The mitochondrial genome (mitogenome) characteristics of the monotypic Lasiocampoidea are largely unknown, because only limited number of mitogenomes is available from this superfamily. In this study, we sequenced the complete mitogenome of the lappet moth, Kunugia undans (Lepidoptera: Lasiocampidae) and compared it to those of Lasiocampoidea and ma

10. Draft genome of a South African strain of Pectobacterium carotovorum subsp. brasiliense
Abstract The draft genome of Pectobacterium carotovorum subsp. brasiliense (Pcb) which causes blackleg of potato was submitted to the NCBI and released with reference number NZ_LGRF00000000.1. The estimated genome size based on the draft genome assembly is 4,820,279 bp from 33 contigs ranging in length from 444 to 1,660,019 nucleotides. The genome annotation

11. The rearranged mitochondrial genome of Leptopilina boulardi (Hymenoptera: Figitidae), a parasitoid wasp of Drosophila
Abstract The partial mitochondrial genome sequence of Leptopilina boulardi (Hymenoptera: Figitidae) was characterized. Illumina sequencing was used yielding 35,999,679 reads, from which 102,482 were utilized in the assembly. The length of the sequenced region of this partial mitochondrial genome is 15,417 bp, consisting of 13 protein-coding, two rRNA, and 21

12. Prevalência de mutações no DNA mitocondrial em pacientes esporádicos com deficiência auditiva sensorioneural não sindrômica
Resumo Introdução: Diversas mutações do DNA mitocondrial tem sido descritas, em diferentes famílias, associadas à deficiência auditiva não sindrômica. No entanto, pouco se sabe sobrea prevalência dessas mutações em pacientes esporádicos com deficiência auditiva sensorioneural não sindrômica. Objetivo: A finalidade do nosso estudo foi inve
