Caracterização de uma nova estirpe do Tomato mosaic virus isolada de tomateiro no Estado de São Paulo

Abstract: Um vírus isolado em Guaratinguetá, SP, de tomateiro (Lycoporsicon esculentum) 'Santa Clara' com sintomas característicos de virose, foi estudado por meio de plantas indicadoras e de hospedeiras diferenciais pertencentes a linhagens homozigotas de tomateiro, ensaios de estabilidade in vitro, purificação, contrastação negativa, testes sorológicos de ELISA-PTA e imunomicroscopia eletrônica, utilizando-se anti-soros contra diferentes vírus do gênero Tobamovirus. O isolado infetou plantas de espécies de amarantácea… Show more

“…(AJ 417701), Hibiscus rosa-sinensis (11) and Eustoma russellianum (13). It is worth mentioning that an identity of about 86% with the Brazilian ToMV sequence was observed (Table 1), supporting the suggestion that the virus might be considered an intermediary strain of ToMV (22).…”

“…TMV-Sapopema could not infect Petunia hybrida described as a host for TMV and ToMV (Moreira et al, 2003;Hollings and Huttinga, 1976). However, severe mosaic symptoms developed in tomato 'Santa Clara' and 'Avansus' with strong leaf narrowing, while the cultivar Carmem developed only mild symptoms.…”

“…Misinterpretation of host range symptoms for species determination in Tobamovirus is very common. There are reports of isolates capable to overcome the resistance of some tomato varieties expressing, for example, the resistance factor 'Tm-1' that provides resistance for ToMV, and the resistance factors 'Tm-2' and 'Tm-2 2 ' for TMV (Moreira et al, 2003). Additionally few indicator plants distinguish reliably between TMV and ToMV (Jacobi et al 1998).…”

“…Consideraram-se positivas as leituras obtidas de material infetado que apresentavam valores três vezes superiores aos controles negativos. Para a extração de RNAs totais, 1g de amostras foliares de pimentão infetado com o isolado PMMoV-BR apresentando mosaico brando e nanismo, foram submetidas ao procedimento descrito por Moreira et al (2003). Amostras de RNAs totais de folhas de pimentão sadias constituíram o controle negativo.…”
