1. Passiflora cristalina and Passiflora miniata: meiotic characterization of two wild species for use in breeding
Abstract Passiflora cristalina and Passiflora miniata are two new wild species found in the southern Amazon region. This study aimed to analyze the meiotic behavior of the two species, by meiotic analysis, meiotic index and pollen grain viability, using routine methodologies of the laboratory. By the meiotic analysis, the two species were diploid with 18 chr

2. Microbial interactions: ecology in a molecular perspective
ABSTRACT The microorganism-microorganism or microorganism-host interactions are the key strategy to colonize and establish in a variety of different environments. These interactions involve all ecological aspects, including physiochemical changes, metabolite exchange, metabolite conversion, signaling, chemotaxis and genetic exchange resulting in genotype sel

3. Nosocomial and community infections due to class A extended-spectrum β-lactamase (ESBLA)-producing Escherichia coli and Klebsiella spp. in southern Brazil
OBJECTIVES: To determine the prevalence of class A extended spectrum β-lactamases (ESBL)-producing Escherichia coli and Klebsiella spp., and to investigate clonality among ESBL-producing isolates of nosocomial and community infections. METHODS: The study involved 354 nosocomial infections samples and 992 community infections samples, obtained between 2003 a

4. Molecular analysis of an Integrative Conjugative Element, ICEH, present in the chromosome of different strains of Mycoplasma hyopneumoniae
Diversification of bacterial species and pathotypes is largely caused by lateral gene transfer (LGT) of diverse mobile DNA elements such as plasmids, phages, transposons and genomic islands. Thus, acquisition of new phenotypes by LGT is very important for bacterial evolution and relationship with hosts. This paper reports a 23 kb region containing fourteen C

5. Padrões de evolução genica e genomica em Moniliophthora perniciosa (Basiomicota, Agaricales), agente causal da vassoura de bruxa / Paterns of genomic evolution in Moniliophthora perniciosa (Basiomicota, Agaricales) causal agent of witche s broom disease
Moniliophthora perniciosa (Stahel) Aime &Phillips-Mora is a hemibiotrophic basidiomycete fungus that causes witches broom disease in cocoa (Theobroma cacao L.). This disease is characterized by the production of hyperplasic and hypertrophic stems and parthenogenetic fruits during biotrophic life-phasee, followed by necrosis of infected tissues during necrotr

6. Estudo do mecanismo de transferência horizontal da sequência de inserção IS1245, específica de Mycobacterium avium, para Mycobacterium kansasii / Study of the mechanism of horizontal transfer of insertion sequence IS1245, specific of Mycobacterium avium, to Mycobacterium kansasii
Mycobacterium avium and Mycobacterium kansasii are non-tuberculous mycobacteria frequently isolated in infections from HIV positive patients. In a previous study from our laboratory, a mixed culture of M. avium and M. kansasii from a bone marrow isolate of an HIV positive patient was studied. The analysis of isolated colonies allowed the detection of the ins

7. Subsidy for genetic transformation of Catasetum pileatum (Orchidaceae) plants using root and shoot meristematic tissues / Subsídios à transformação genética de plantas de Catasetum pileatum (Orchidaceae) por meio de tecidos merismáticos radiculares e caulinares
Research on in vitro conversion of root apical meristems into buds in Catasetum has contributed to a better understanding of competence, induction and cellular determination processes during plant development. Nowadays It demands advances in molecular studies. To achieve this, the use of transgenic plants is an important working tool. Furthermore, genetic tr

8. Seleção de tipos de Ocimum basilicum L. de cor púrpura para o mercado de plantas ornamentais / Ocimum basilicum L. purple color pattern selection for the plant ornamental market
Ocimum basilicum is a very important species for food industry (sauce), as medicinal plant and aromatic uses. Recently it became interesting for the plant ornamental market with purple colored varieties. The purple color instability is a problem to be solved in order to improve the commercial exploitation of such plants. The main purpose of this work was to

10. Genetic transformation of sweet orange (Citrus sinensis L. Osbeck) with the cecropin MB39 gene and evaluation of transgenic plants inoculated with Xylella fastidiosa Wells et al. / Transformação genética de laranja doce (Citrus sinensis L. Osbeck) com o gene cecropin MB39 e avaliação de plantas transgênicas inoculadas com Xylella fastidiosa Wells et al.
A obtenção de plantas geneticamente modificadas tornou-se uma ferramenta biotecnológica de grande valor, contribuindo nos programas de melhoramento. Plantas transgênicas contendo genes de peptídeos antibacterianos são uma boa alternativa nos programas visando resistência às bactérias. A cecropina é um peptídeo isolado de inseto que apresenta açã

11. Formação de micorriza arbuscular e análise do transcritoma de raízes de cana-de-açúcar colonizadas por Glomus clarum na presença de herbicidas / Arbuscular mycorrhizal formation and transcriptome analyses of sugarcane roots colonized by Glomus clarum in the presence of herbicides
The arbuscular mycorrhizae (AM) are symbiotic root-fungus associations that play a key role in natural and agricultural ecosystems, through the enhancement of nutrients absorption in the soil and its transference into the plants. The AM may promote the growth of many plants, among them are the sugarcane. Even thought the herbicide utilized in the agriculture
