During 2009 and 2010, a survey was conducted in pepper crops to detect the possible presence of Pepper mild mottle virus (PMMoV) in Serbia. A total of 239 pepper samples from 39 crops at 26 localities were collected and analyzed for the presence of PMMoV, Cucumber mosaic virus (CMV), Potato virus Y (PVY), and Alfalfa mosaic virus (AMV), using DAS-ELISA test. Although it was detected in a small percentage, PMMoV could pose a threat to pepper production in Serbia due to its rapid seed-borne spread. Presence of PMMoV was confirmed by serological and biological detection, followed by conventional reverse transcription RT-PCR, using primers specific for the RNA-dependent RNA polymerase (RdRp) and the coat protein (CP) genes. Molecular identification confirmed that the Serbian isolates belong to PMMoV pathotypes P1,2 which do not break the resistance gene L3. Reconstructed phylogenetic tree confirmed the allocation of the Serbian isolates together with the majority of PMMoV isolates which belong to pathotypes P1,2. This study represents the first serological and molecular characterization of PMMoV infection of pepper in Serbia, and provides important data on the population structure. The obtained data could have great influence on pepper production in Serbia as well as future pepper resistance breeding in the country.

Sementes de pimenta (Capsicum baccatum) 'Dedo de Moça' destinadas ao plantio comercial e adquiridas no município de São Paulo, SP, analisadas quanto à presença de vírus, por meio de testes biológicos e sorológicos revelaram-se infetadas por uma estirpe do Pepper mild mottle virus (PMMoV). Para confirmar a identidade do isolado, promoveu-se a RT-PCR com oligonucleotídeos que flanqueiam a ORF da capa protéica de espécies do gênero Tobamovirus do subgrupo 1. Os fragmentos de DNA amplificados, quando seqüenciados e comparados com outros isolados de tobamovírus depositados no GenBank, apresentaram valores de identidade de nucleotídeos entre 94 e 100% com outras seqüências de PMMoV, inferiores a 75% para as demais espécies de tobamovírus do subgrupo I (Tobacco mosaic virus, Tomato mosaic virus e Odontoglossum ringspot virus) e 65% para os tobamovírus dos subgrupos II e III. O PMMoV-BR revelou 100% de identidade com isolados japoneses, sugerindo que este patógeno pode ter sido introduzido daquele país. A seqüência de aminoácidos deduzidos da capa protéica indicou também, que este isolado não é capaz de quebrar a resistência do gene L3 de Capsicum spp. Fato confirmado pelos sintomas causados nas hospedeiras diferenciais de Capsicum spp., verificando-se que este isolado não foi capaz de infetar plantas de C. chinense (L3) e C. chacoense (L4). Estes resultados confirmaram a importância da caracterização dos isolados de tobamovírus, fundamental para adequação de medidas de controle, principalmente, prevenindo a entrada e posterior disseminação do patógeno em novas áreas de cultivo.

A resistência em Capsicum spp a tobamovírus é governada pelos genes L¹ a L4. Baseado na capacidade de alguns isolados suplantarem a resistência destes genes, os tobamovírus podem ser classificados nos patótipos P0, P1, P1-2 e P1-2-3. No Brasil, até o momento as três espécies de tobamovírus conhecidas são: Tobacco mosaic virus (TMV), Tomato mosaic virus (ToMV), pertencentes aos patótipos P0 e Pepper mild mottle virus (PMMoV) pertencente ao patótipo P1-2, respectivamente e podem infectar pimentas e pimentões. Oitenta e seis genótipos de pimentão e pimenta foram avaliados quanto à resistência a tobamovírus, sendo 62 de Capsicum annuum, 18 de C. baccatum e seis de C. chinense. Oito acessos de C. annuum, seis de C. baccatum e os acessos ICA #39, Pimenta de cheiro e PI 152225 de C. chinense apresentaram reação de hipersensibilidade ao ToMV, enquanto que o acesso Ancho de C. annuum foi considerado tolerante, permanecendo assintomático, porém permitindo a recuperação do vírus quando inoculado em Nicotiana glutinosa. Para o PMMoV patótipo P1,2 foram avaliados os acessos de pimentão e pimenta considerados resistentes ao ToMV. Somente o PI 152225 de C. chinense desencadeou reação de hipersensibilidade ao PMMoV, sendo fonte potencial de resistência para programas de melhoramento a este vírus no Brasil.

Pepper Mild Mottle Virus

Cucumber mosaic virus (CMV) and Pepper mild mottle virus (PMMoV) causes severe economic loss in crop productivity of both agriculture and horticulture crops in Korea. The previous surveys showed that naturally available biopolymer material – chitosan (CS), which is from shrimp cells, reduced CMV accumulation on pepper. To improve the antiviral activity of CS, it was synthesized to form phosphate cross-linked chitosan (PCS) and compared with the original CS. Initially, the activity of CS and PCS (0.01%, 0.05%, and 0.1% concentration) compound against PMMoV infection and replication was tested using a half-leaf assay on Nicotiana glutinosa leaves. The total number of local lesions represented on a leaf of N. glutinosa were counted and analyzed with phosphate buffer treated leaves as a negative control. The leaves treated with a 0.1% concentration of CS or PCS compounds exhibited an inhibition effect by 40-75% compared with the control leaves. The same treatment significantly reduced about 40% CMV accumulation measured by double antibody sandwich enzyme-linked immunosorbent assay and increased the relative expression levels of the NPR1, PR-1, cysteine protease inhibitor gene, LOX, PAL, SRC2, CRF3 and ERF4 genes analyzed by quantitative reverse transcriptase-polymerase chain reaction, in chili pepper plants.
