“…Levels of infection of greenhouse tomatoes from ToMVcontaining plant debris are affected by inoculum concentration (Pares et al, 1996). As the inoculum concentration decreases infection levels decrease and a greater proportion of infections are symptomless or are restricted to the roots.…”

“…But the presence of ToMV was detected in up to 70% of the tomato plants by ELISA tests. Immunoelectron microscopy revealed the presence of ToMV virions in roots and leaves of tomato plants grown on soils containing infective plant debris (Pares et al 1996). The bait plants Chenopodium quinoa were planted in soils amended with ToMV eluted from organic and mineral fractions of soils.…”

Microbial Plant Pathogens-Detection and Disease Diagnosis:

Plant viruses and viroids with obligate parasitism as the mode of existence, have to be in association with living cells of plant hosts always. However, some highly stable viruses have been detected in a free state in soil, water or air. Other viruses depend on the vectors such as insects, mites, nematodes or fungi present in the environment for their spread from infected plants to healthy plants which may be available in the same field or far away. The role of alternative/additional host plant species functioning as sources of virus infection has been demonstrated by applying various diagnostic techniques. The presence of viruses has been detected by employing biological, immunological and nucleic acid-based techniques. The effectiveness and reliability of detection varies significantly. However, molecular techniques have been shown to be more sensitive, specific and fast in providing the results, although they are unable to indicate the level of pathogenic potential of the viruses detected in the environmental samples. Viroids lacking natural vectors and stability outside living cells have been detected in several additional/alternative plant species which may function as reservoir of viroid infection.

The resistance of Capsicum spp to tobamoviruses is conferred by the genes series L 1 to L 4 . Based on the ability of some isolates to overcome the resistance genes, the tobamovirus can be classificated in the pathotypes P 0 , P 1 , P 1-2 and P 1-2-3 . In Brazil, at this moment there are three species of tobamovirus: Tobacco mosaic virus (TMV), Tomato mosaic virus (ToMV), belonging to pathotype P 0 and Pepper mild mottle virus (PMMoV) belonging to pathotype P 1-2 respectively, that can infect sweet and hot peppers. Eighty-six genotypes of sweet and hot pepper were evaluated for the resistance to tobamovirus.Cezar, M.A.; Krause-Sakate, R.; Pavan, M.A.; Costa, C. P. Evaluation of resistance of Capsicum spp. genotypes to tobamovirus. Summa Phytopathologica, v.35, n.1, p.39-43, 2009 Keywords: Sweet pepper, hot pepper, ToMV, TMV and PMMoV Eigth genotypes of C. annuum, five of C. baccatum and the three genotypes ICA #39, Pimenta de cheiro and PI 152225 of C. chinense reacted with hipersensibility to ToMV, while the genotype Ancho of C. annuum was considered tolerant to ToMV, remaining symptomless but allowing the multiplication of the virus. The genotypes considered resistant to ToMV, were evaluated for the reaction to P 1,2 PMMoV. Only the PI 152225 of C. chinense reacted with hipersensibility to PMMoV, indicating that it could be used as a potential source of resistance in the breeding programs from Brazil. As pimentas e pimentões, pertencentes ao gênero Capsicum spp., são amplamente cultivadas em todo mundo (16,19). Ocupam uma posição importante no consumo brasileiro de hortaliças destacandose entre as dez de maior consumo, tanto em valor, quanto em volume comercializado (8). A produtividade média da pimenta pode variar de acordo com a cultivar. Pimentas do tipo 'Dedo-de-moça' e 'Tabasco' apresentam uma produtividade de 10 t/ha, no caso das pimentas do tipo 'Malagueta', estas podem atingir uma produtividade de 4 ton/ha, e as do tipo 'Jalapeño' podendo atingir 30 t/ha (26). Enquanto que a cultura do pimentão atinge uma produtividade média ao redor de 30 toneladas por ha. (26). Palavras-chave adicionais:Uma das limitações para estas culturas são as doenças de origem viral. Várias espécies do gênero Tobamovirus podem infectar Capsicum spp., tais como o: Tobacco mosaic virus (TMV), Tomato mosaic virus (ToMV) e o Pepper mild mottle virus (PMMoV) sendo este último inicialmente relatado no Brasil infectando plantas de pimenta e pimentão em cultivos protegidos desde 2001 (4, 9, 14).Os tobamovírus são eficientemente transmitidos por contato entre plantas, pela ação do homem, ferramentas e utensílios utilizados nos tratos culturais exigidos pela cultura, principalmente em condições de cultivo protegido (22). Além disto são transmitidos na forma de contaminantes na parte externa das sementes, e estas são consideradas a principal fonte de disseminação a longas distâncias (10). Estes vírus possuem alta estabilidade, permanecendo viáveis por longos períodos em restos culturais no solo (5, 7,17,18).A resistência a toba...
