“…The resulting protein consists of 156 amino acids, with a calculated Mr of 17110. This value differs from the previous report of 158 amino acids for the coat protein of an Italian isolate of PMMV (Wetter et al, 1984), determined by amino acid analysis. Although PMMV-S and PMMV are different isolates, which can be distinguished by their responses in Capsicum spp.…”

“…It is found infecting pepper cultivars with genetically incorporated resistance to TMV and ToMV. The infection by this virus produces important economic losses all over the world in crops grown under plastic or glass (Wetter & Conti, 1988). Additionally, PMMV is unable to infect tomato plants and possesses a reduced capability to replicate and/or accumulate in tobacco plants when compared to TMV The nucleotide sequence data reported in this paper will appear in the EMBL, GenBank and DDBJ nucleotide sequences databases under the accession number M81413.…”

The entire genomic RNA of a Spanish isolate of pepper mild mottle virus (PMMV-S), a resistance-breaking virus in pepper, was cloned and sequenced and shown to be similar to other tobamoviruses in its genomic organization. It consisted of 6357 nucleotides (nt) and contained four open reading frames (ORFs) which encode a 126K protein and a readthrough 183K protein (nt 70 to 4908), a 28K protein (nt 4909 to 5682) and a 17.5K coat protein (nt 5685 to 6158). This is the first tobamovirus in which none of the ORFs overlap. Both its nucleic acid and predicted protein sequences were compared with the previously determined sequences of other tobamoviruses. The variations and similarities found and their relationship with the pathogenicity of this virus are discussed.

“…This has shown that the coat proteins of ToMV and PMMV are evolutionarily very closely related; serological studies have also found a close relationship between ToMV and PMMV (Wetter et al, 1984;Alonso et al, 1989). Thus the close similarity of the 3' terminal noncoding regions of PMMV-S RNA and ToMV RNA confirms the close relationship between the viruses.…”

“…A Spanish isolate of pepper mild mottle virus (PMMV-S), a newly proposed member of the tobamovirus group (Wetter et al, 1984), was found to be infecting pepper plants which were resistant to tobacco mosaic virus (TMV) and tomato mosaic virus (ToMV) (Alonso et al, 1989). The symptoms induced by PMMV-S in pepper plants are almost imperceptible until the development of fruit, which is deformed.…”

Nucleotide Sequences of 5' and 3' Non-coding Regions of Pepper Mild Mottle Virus Strain S RNA

SUMMARYThe nucleotide sequences of the 5' and 3' non-coding regions of pepper mild mottle virus strain S (PMMV-S) RNA were determined; they are more like corresponding sequences of tomato mosaic virus (ToMV) RNA than those of any other tobamovirus reported so far. The 5' leader contains a 68 nucleotide guanosine-free sequence which differs in several nucleotides from the corresponding sequences in genomic RNA of tobacco mosaic virus (TMV) and ToMV. The messenger activity of PMMV-S RNA in vitro and the polypeptide translation products made were similar to those of TMV RNA. It therefore seems unlikely that qualitative or quantitative differences in translation in vivo account for the milder symptoms induced by PMMV-S, and its lesser replication, than TMV. The 3' non-coding region of PMMV-S RNA is 199 nucleotides long and can be folded into the same secondary structure as the RNA of other tobamoviruses.

“…Todos isolados de TMV e ToMV até então estudados enquadram-se como patótipo P 0 e são incapazes de suplantar a resistência em plantas de Capsicum que contém o gene L 1 (20), enquanto que, plantas com os genes de resistência L 2 e L 3 são facilmente infectadas pelos patótipos P 1,2 e P 1,2,3 de PMMoV, respectivamente (16). No Brasil, até o momento, somente foi verificado o patótipo P 1,2 de PMMoV (4, 9, 14), porém em países, como Espanha (11,25), Itália (27), e o Japão (24) já foi observado o patótipo P 1,2,3 de PMMoV e este vem sendo considerado um sério entrave à produção de pimentas e pimentões. Somente o gene L 4 é capaz de conferir resistência a este patótipo (12).…”

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...
