Elisabeth Mendes Martins De Moura Diversidade De Vírus DNA
Elisabeth Mendes Martins de Moura Diversidade de vírus DNA autóctones e alóctones de mananciais e de esgoto da região metropolitana de São Paulo Tese apresentada ao Programa de Pós- Graduação em Microbiologia do Instituto de Ciências Biomédicas da Universidade de São Paulo, para obtenção do Titulo de Doutor em Ciências. Área de concentração: Microbiologia Orienta: Prof (a). Dr (a). Dolores Ursula Mehnert versão original São Paulo 2017 RESUMO MOURA, E. M. M. Diversidade de vírus DNA autóctones e alóctones de mananciais e de esgoto da região metropolitana de São Paulo. 2017. 134f. Tese (Doutorado em Microbiologia) - Instituto de Ciências Biomédicas, Universidade de São Paulo, São Paulo, 2017. A água doce no Brasil, assim como o seu consumo é extremamente importante para as diversas atividades criadas pelo ser humano. Por esta razão o consumo deste bem é muito grande e consequentemente, provocando o seu impacto. Os mananciais são normalmente usados para abastecimento doméstico, comercial, industrial e outros fins. Os estudos na área de ecologia de micro-organismos nos ecossistemas aquáticos (mananciais) e em esgotos vêm sendo realizados com mais intensidade nos últimos anos. Nas últimas décadas foi introduzido o conceito de virioplâncton com base na abundância e diversidade de partículas virais presentes no ambiente aquático. O virioplâncton influencia muitos processos ecológicos e biogeoquímicos, como ciclagem de nutriente, taxa de sedimentação de partículas, diversidade e distribuição de espécies de algas e bactérias, controle de florações de fitoplâncton e transferência genética horizontal. Os estudos nesta área da virologia molecular ainda estão muito restritos no país, bem como muito pouco se conhece sobre a diversidade viral na água no Brasil. -

Abstract Bacteriophages, viruses that infect bacteria, are the most abundant biological entities on Earth. Siphophages, accounting for ~60% of known phages, bear a long, flexible tail that allows host recognition and safe delivery of the DNA from the capsid to the cytoplasm of the infected cell. -

Multiple Origins of Prokaryotic and Eukaryotic Single-Stranded DNA Viruses from Bacterial and Archaeal Plasmids
ARTICLE https://doi.org/10.1038/s41467-019-11433-0 OPEN Multiple origins of prokaryotic and eukaryotic single-stranded DNA viruses from bacterial and archaeal plasmids Darius Kazlauskas 1, Arvind Varsani 2,3, Eugene V. Koonin 4 & Mart Krupovic 5 Single-stranded (ss) DNA viruses are a major component of the earth virome. In particular, the circular, Rep-encoding ssDNA (CRESS-DNA) viruses show high diversity and abundance 1234567890():,; in various habitats. By combining sequence similarity network and phylogenetic analyses of the replication proteins (Rep) belonging to the HUH endonuclease superfamily, we show that the replication machinery of the CRESS-DNA viruses evolved, on three independent occa- sions, from the Reps of bacterial rolling circle-replicating plasmids. The CRESS-DNA viruses emerged via recombination between such plasmids and cDNA copies of capsid genes of eukaryotic positive-sense RNA viruses. Similarly, the rep genes of prokaryotic DNA viruses appear to have evolved from HUH endonuclease genes of various bacterial and archaeal plasmids. Our findings also suggest that eukaryotic polyomaviruses and papillomaviruses with dsDNA genomes have evolved via parvoviruses from CRESS-DNA viruses. Collectively, our results shed light on the complex evolutionary history of a major class of viruses revealing its polyphyletic origins. 1 Institute of Biotechnology, Life Sciences Center, Vilnius University, Saulėtekio av. 7, Vilnius 10257, Lithuania. 2 The Biodesign Center for Fundamental and Applied Microbiomics, School of Life Sciences, Center for Evolution and Medicine, Arizona State University, Tempe, AZ 85287, USA. 3 Structural Biology Research Unit, Department of Integrative Biomedical Sciences, University of Cape Town, Rondebosch, 7700 Cape Town, South Africa. -

Characterization and Genome Organization of New Luteoviruses and Nanoviruses Infecting Cool Season Food Legumes
Adane Abraham (Autor) Characterization and Genome Organization of New Luteoviruses and Nanoviruses Infecting Cool Season Food Legumes https://cuvillier.de/de/shop/publications/2549 Copyright: Cuvillier Verlag, Inhaberin Annette Jentzsch-Cuvillier, Nonnenstieg 8, 37075 Göttingen, Germany Telefon: +49 (0)551 54724-0, E-Mail: [email protected], Website: https://cuvillier.de CHAPTER 1 General Introduction Viruses and virus diseases of cool season food legumes Legume crops play a major role worldwide as source of human food, feed and also in crop rotation. Faba bean (Vicia faba L.), field pea (Pisum sativum L.), lentil (Lens culinaris Medik.), chickpea (Cicer arietinum L.), and grasspea (Lathyrus sativus L.), collectively re- ferred to as cool season food legumes (Summerfield et al. 1988) are of particular importance in developing countries of Asia, North and Northeast Africa where they provide a cheap source of seed protein for the predominantly poor population. Diseases including those caused by viruses are among the main constraints reducing their yield. Bos et al. (1988) listed some 44 viruses as naturally infecting faba bean, chickpea, field pea and lentil worldwide. Since then, a number of new viruses were described from these crops including Faba bean necrotic yellows virus (FBNYV) (Katul et al. 1993) and Chickpea chlorotic dwarf virus (CpCDV) (Horn et al. 1993), which are widespread and economically important. Most of the viruses of cool season food legumes are known to naturally infect more than one host within this group of crops (Bos et al. 1988, Brunt et al. 1996 and Makkouk et al. 2003a). Virus symptoms in cool season food legumes vary depending on the virus or its strain, host species or cultivar and the prevailing environmental conditions. -

We especially focus on suc- cessful ability to evolutionarily adapt in the face of environmental change. Viruses are often challenged by dynamic environments, such as host immune function and evolved resistance as well as abiotic fluctuations in temperature, moisture, and other stressors that reduce virion stability. Despite these chal- lenges, our experimental evolution studies show that viruses can often readily adapt, and novel virus emergence in humans and other hosts is increasingly problematic. We additionally consider whether viruses are advantaged in evolvability—the capacity to evolve—and in avoidance of extinction. On the basis of these different ways of gauging biological success, we conclude that viruses are the most successful inhabitants of the biosphere. -
