In Capsicum, the resistance conferred by the L 2 gene is effective against all of the pepper-infecting tobamoviruses except Pepper mild mottle virus (PMMoV), whereas that conferred by the L 4 gene is effective against them all. These resistances are expressed by a hypersensitive response, manifested through the formation of necrotic local lesions (NLLs) at the primary site of infection. The Capsicum L 2 gene confers resistance to Paprika mild mottle virus (PaMMV), while the L 4 gene is effective against both PaMMV and PMMoV. The PaMMV and PMMoV coat proteins (CPs) were expressed in Capsicum frutescens (L 2 L 2) and Capsicum chacoense (L 4 L 4) plants using the heterologous Potato virus X (PVX)-based expression system. In C. frutescens (L 2 L 2) plants, the chimeric PVX virus containing the PaMMV CP was localized in the inoculated leaves and produced NLLs, whereas the chimeric PVX containing the PMMoV CP infected the plants systemically. Thus, the data indicated that the PaMMV CP is the only tobamovirus factor required for the induction of the host response mediated by the Capsicum L 2 resistance gene. In C. chacoense (L 4 L 4) plants, both chimeric viruses were localized to the inoculated leaves and produced NLLs, indicating that either PaMMV or PMMoV CPs are required to elicit the L 4 gene-mediated host response. In addition, transient expression of PaMMV CP into C. frutescens (L 2 L 2) leaves and PMMoV CP into C. chacoense (L 4 L 4) leaves by biolistic co-bombardment with a β-glucuronidase reporter gene led to the induction of cell death and the expression of host defence genes in both hosts. Thus, the tobamovirus CP is the elicitor of the Capsicum L 2 and L 4 gene-mediated hypersensitive response.

The pepper mild mottle virus (PMMoV-S) (an L3 hypersensitive response [HR]-inducer strain) coat protein was expressed in Capsicum chinense (L3L3) plants with the heterologous potato virus X (PVX)-based expression system. The chimeric virus was localized in the inoculated leaves and induced the HR, thus indicating that the tobamoviral sequences that affect induction of the HR conferred by the L3 resistance gene reside in the coat protein gene. Furthermore, transient expression of the PMMoV-S coat protein in C. chinense leaves by biolistic co-bombardment with a plasmid expressing the β-glucuronidase (GUS) gene leads to the induction of cell death and expression of host defense genes. Thus, the coat protein of PMMoV-S is the elicitor of the Capsicum spp. L3 resistance gene-mediated HR.

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.

Enteric viruses (EV) are the largest contributors to foodborne illness and outbreaks globally. Their ability to persist in the environment, coupled with the challenges experienced in environmental monitoring create a critical aperture through which agricultural crops may become contaminated. This study involved a seventeen-month investigation of select human enteric viruses and viral indicators in non-traditional irrigation water sources, surface and reclaimed waters, in the Mid-Atlantic region of the United States. Real-time quantitative PCR was used for detection of Aichi virus, hepatitis A virus, noroviruses GI and GII. Pepper mild mottle virus (PMMoV), a common viral indicator of human fecal contamination, was also evaluated along with atmospheric (air and water temperature, cloud cover, and precipitation 24 h, 7 d and 14 d prior to sample collection) and physicochemical (dissolved oxygen, pH, salinity and turbidity) data to determine if there were any association between EV and measured parameters. EV were detected more frequently in reclaimed waters (32%, n=22) than in surface waters (4%, n=49) similar to PMMoV detection frequency in surface (33%, n=42) and reclaimed (67%, n=21) water. Our data show a significant correlation between EV and PMMoV (R2=0.628; p<0.05) detection in reclaimed water samples, but not in surface waters (R2=0.476; p=0.78). Water salinity significantly affected the detection of both EV and PMMoV (p<0.05) as demonstrated by logistic regression analyses. These results provide relevant insights into the extent and degree of association between human enteric (pathogenic) viruses and water quality data in Mid-Atlantic surface and reclaimed waters as potential sources for agricultural irrigation. IMPORTANCE Microbiological analysis of agricultural waters is fundamental to ensure microbial food safety. The highly variable nature of non-traditional sources of irrigation water are particularly difficult to test for the presence of viruses. Multiple characteristics influence viral persistence in a water source as well as affect the recovery and detection methods which are employed. Testing for a suite of viruses in water samples is often too costly and labor intensive, making identification of suitable indicators for viral pathogen contamination necessary. The results from this study address two critical data gaps: enteric virus prevalence in surface and reclaimed waters of the Mid-Atlantic region of the United States and subsequent evaluation of physicochemical and atmospheric parameters used to inform the potential for use of indicators of viral contamination.
