1. [PROVISIONAL] Molecular characterization and transcription analysis of DNA methyltransferase genes in tomato (Solanum lycopersicum)
Abstract DNA methylation plays an important role in plant growth and development, gene expression regulation and maintenance of genome stability. However, only little information regarding development- or stress-related DNA methyltransferases (MTases) genes is available in tomato. Here, we report the analysis of nine tomato MTases which were categorized into

2. Draft genome of the Leptospira interrogans strains, Acegua, RCA, Prea, and Capivara, obtained from wildlife maintenance hosts and infected domestic animals
In the present paper, we announce new draft genomes of four Leptospira interrogans strains named Acegua, RCA, Prea, and Capivara. These strains were isolated in the state of Rio Grande do Sul, Brazil, from cattle, dog, Brazilian guinea pig, and capybara, respectively.

3. Gene expression profile of oxidative stress in the lung of inbred mice after intestinal ischemia/reperfusion injury
PURPOSE: To determine the gene expression profile associated with oxidative stress and antioxidant defense in the lung tissue of mice subjected to intestinal ischemia and reperfusion.METHODS: Twelve male, inbred mice (C57BL/6) were randomly assigned to one of two groups. The control group (CG) underwent anesthesia and laparotomy and was observed for 120 minu

4. Overall picture of expressed Heat Shock Factors in Glycine max, Lotus japonicus and Medicago truncatula
Heat shock (HS) leads to the activation of molecular mechanisms, known as HS-response, that prevent damage and enhance survival under stress. Plants have a flexible and specialized network of Heat Shock Factors (HSFs), which are transcription factors that induce the expression of heat shock proteins. The present work aimed to identify and characterize the Gl

5. Caracterização do gene LmHUS1 e de sua participação no fenômeno de amplificação gênica em Leishmania spp. / LmHUS1 gene characterization and its participation in the gene amplification in Leishmania spp.
The protozoan parasite Leishmania presents a dynamic and plastic genome in which gene amplification and chromosome translocations are common phenomena. Such plasticity hints at the necessity of dependable genome maintenance pathways. Eukaryotic cells have evolved checkpoint control systems that recognize altered DNA structures and halt cell cycle progression

6. Clonagem e expressão do gene da tiorredoxina 1 de Paracoccidioides brasiliensis em Pichia pastoris / Cloning and expression of the thioredoxin 1 gene of Paracoccidioides brasiliensis in pichia pastoris
The termodimorphic fungus Paracoccidioides brasiliensis is the etiological agent of paracoccidioidomycosis, a human systemic mycosis of high prevalence in Latin America. P. brasiliensis is exposed to oxidative stress (OS) caused by reactive oxygen species (ROS) produced by the defense cells of the human host. When the invasion by pathogens occurs, the host d

7. Evolutionary origins of human apoptosis and genome-stability gene networks
Apoptosis is essential for complex multicellular organisms and its failure is associated with genome instability and cancer. Interactions between apoptosis and genome-maintenance mechanisms have been extensively documented and include transactivation-independent and -dependent functions, in which the tumor-suppressor protein p53 works as a ‘molecular node�

8. Comparative genome analysis of proteases, oligopeptide uptake and secretion systems in mycoplasma spp
Mycoplasmas are very fastidious in their nutritional requirements for in vitro growth and have limited biosynthetic capacity, a reflection of their reduced genomes. As a result, these bacteria depend upon external metabolites for nutrition and growth and have developed dependence on their hosts for survival and maintenance. Protein degradation and peptide im

9. Adaptabilidade de híbridos entre Gossypium barbadense E G. hirsutum N contendo o gene cry1Ac
Hybrids among transgenic plants and related species are expected to occur if they are sympatric and when there are not crossing barriers; as is the case, in Brazil, of cry1Ac transgenic cotton and Gossypium barbadense. This species has been maintained as dooryard plants, and should be preserved as a genetic resource. Hybrids were evaluated about traits relat

10. Analysis of the expression of genes involved in the maintenance of copper homeostasis in the human pathogen Paracoccidioides brasiliensis / Análise da expressão de genes envolvidos na manutenção da homeostase de cobre no patógeno humano Paracoccidioides brasiliensis
The fungus Paracoccidioides brasiliensis is a human pathogen with a wide distribution in Latin America. The fungus causes paracoccidioidomycosis when mycelia reachs the lungs. The success of the infection depends on the acquisition of essential micronutrients such as copper, which is required as cofactor for a variety of enzymes important in biological in se

11. Analysis of the expression of genes involved in the maintenance of copper homeostasis in the human pathogen Paracoccidioides brasiliensis / Análise da expressão de genes envolvidos na manutenção da homeostase de cobre no patógeno humano Paracoccidioides brasiliensis
O fungo Paracoccidioides brasiliensis é um patógeno humano com ampla distribuição na América Latina. O fungo causa a paracoccidioidomicose quando propágulos da fase miceliana atingem os pulmões do hospedeiro. O sucesso da infecção depende da aquisição de micronutrientes essenciais como o cobre, o qual é requerido como cofator por uma diversidade
