Resumo: Garlic viruses often occur in mixed infections under field conditions. In this study, garlic samples collected in three geographical areas of Brazil were tested by Dot-ELISA for the detection of allexiviruses using monoclonal specific antibodies to detect Garlic virus A (GarV-A), Garlic virus B (GarV-B), Garlic virus C (GarV-C) and a polyclonal antiserum able to detect the three virus species mentioned plus Garlic virus D (GarV-D). The detected viruses were biologically isolated by successive passages through Chenopodium quinoa. Reverse Transcriptase Polimerase Chain Reaction (RT-PCR) was performed using primers designed from specific regions of the coat protein genes of Japanese allexiviruses available in the Genetic Bank of National Center of Biotechnology Information (NCBI). By these procedures, individual garlic virus genomes were isolated and sequenced. The nucleotide and amino acid sequence analysis and the one with serological data revealed the presence of three distinct allexiviruses GarV-C, GarV-D and a recently described allexivirus, named Garlic mite-borne filamentous virus (GarMbFV), in Brazil.

Neste estudo, um complexo viral de alho, coletado em campo, em três regiões geográficas, foi testado com anti-soros monoclonais específicos para Garlic virus A (GarV-A), Garlic virus B (GarV-B), Garlic virus C (GarV-C) e um anti-soro policlonal capaz de detectar os três vírus mencionados e Garlic virus D (GarV-D). Procedeu-se à amplificação por transcriptase reversa-reação em cadeia da polimerase (RT-PCR) usando oligonucleotídeos sintetizados a partir de regiões específicas de genes de proteínas capsidiais de allexivirus japoneses e disponíveis no GeneBank (National Center of Biotechnology Information - NCBI). Por esse procedimento, vírus individuais foram isolados e seqüenciados. Os vírus detectados foram biologicamente isolados por meio de sucessivas inoculações em Chenopodium quinoa. A análise das seqüências de nucleotídeos, de aminoácidos e os resultados sorológicos revelaram a presença de três espécies distintas de allexivirus GarV-C, GarV-D e Garlic mite-borne filamentous virus (GarMbFV) no Brasil.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraMelo Filho, Péricles de AlbuquerqueNagata, TatsuyaDusi, André NepomucenoBuso, José AmauriTorres, Antonio CarlosEiras, MarceloResende, Renato de Oliveira2004-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6832Pesquisa Agropecuaria Brasileira; v.39, n.8, ago. 2004; 735-740Pesquisa Agropecuária Brasileira; v.39, n.8, ago. 2004; 735-7401678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/6832/3888info:eu-repo/semantics/openAccess2014-08-21T17:45:38Zoai:ojs.seer.sct.embrapa.br:article/6832Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-21T17:45:38Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
