Pepino mosaic virus (PepMV) was shown to be efficiently transmitted between tomato plants grown in a closed recirculating hydroponic system. PepMV was detected in all plant parts after transmission via contaminated nutrient solution using ELISA, immunocapture RT‐PCR, RT‐PCR, electron microscopy, and by inoculation to indicator plants. Detection of PepMV in nutrient solution was only possible after concentration by ultracentrifugation followed by RT‐PCR. Roots tested positive for PepMV 1–3 weeks after inoculation, and subsequently a rapid spread from the roots into the young leaves and developing fruits was found within 1 week. PepMV was only occasionally detected in the older leaves. None of the infected plants showed any symptoms on fruits, leaves or other organs. Pre‐infection of roots of tomato cv. Hildares with Pythium aphanidermatum significantly delayed PepMV root infections. When mechanically inoculated with PepMV at the 2–4 leaf stage, yield loss was observed in all plants. However, only plants of cv. Castle Rock recorded significant yield losses when infected via contaminated nutrient solution. Yield losses induced by infection with PepMV and/or P. aphanidermatum ranged from 0·4 up to 40% depending on experimental conditions.

Emaravirus (Order Bunyavirales; Family Fimoviridae) is a genus comprising over 20 emerging plant viruses with a worldwide distribution and economic impact. Emaraviruses infect a variety of host plants and have especially become prevalent in important long-living woody plants. These viruses are enveloped, with a segmented, single-stranded, negative-sense RNA genome and are transmitted by eriophyid mites or mechanical transmission. Emaraviruses have four core genome segments encoding an RNA-dependent RNA polymerase, a glycoprotein precursor, a nucleocapsid protein, and a movement protein. They also have additional genome segments, whose number varies widely. We report here that the proteins encoded by these segments form three main homology groups: a homolog of the sadwavirus Glu2 Pro glutamic protease; a protein involved in pathogenicity, which we named “ABC”; and a protein of unknown function, which we named “P55”. The distribution of these proteins parallels the emaravirus phylogeny and suggests, with other analyses, that emaraviruses should be split into at least two genera. Reliable diagnosis systems are urgently needed to detect emaraviruses, assess their economic and ecological importance, and take appropriate measures to prevent their spread (such as routine testing, hygiene measures, and control of mite vectors). Additional research needs include understanding the function of emaravirus proteins, breeding resistant plants, and clarifying transmission modes.

We report the complete nucleotide sequence of the genome of a novel virus in ringspot-diseased common oak (Quercus robur L.). The newly identified pathogen is associated with leaf symptoms such as mottle, chlorotic spots and ringspots on diseased trees. High-throughput sequencing (HTS, Illumina RNASeq) was used to explore the virome of a ringspot-diseased oak that had chlorotic ringspots of suspected viral origin on leaves for several years. Bioinformatic analysis of the HTS dataset followed by RT-PCR enabled us to determine complete sequences of four RNA genome segments of a novel virus. These sequences showed high similarity to members of the genus Emaravirus, which includes segmented negative-stranded RNA viruses of economic importance. To verify the ends of each RNA, we conducted rapid amplification of cDNA ends (RACE). We identified an additional genome segment (RNA 5) by RT-PCR using a genus-specific primer (PDAP213) to the conserved 3´ and 5´termini in order to amplify full-length genome segments. RNA 5 encodes a 21-kDa protein that is homologous to the silencing suppressor P8 of High Plains wheat mosaic virus. The five viral RNAs were consistently detected by RT-PCR in ringspot-diseased oaks in Germany, Sweden, and Norway. We conclude that the virus represents a new member of the genus Emaravirus affecting oaks in Germany and in Scandinavia, and we propose the name "common oak ringspot-associated emaravirus" (CORaV).

The highly infectious Tomato brown rugose fruit virus (ToBRFV) is a new viral threat to tomato production worldwide. In production, the very easy mechanical transmissibility combined with the high resistance in vitro is of great concern. We tested: (i) whether household cleaning products, commercial agricultural detergents, and an authorized plant protectant are suitable for cleaning contaminated clothing, and (ii) whether infectious viruses remain in the resulting cleaning water. The evaluation of the sanitation effect was performed using bioassays, by counting ToBRFV-associated necrotic local lesions on Nicotiana tabacum cv. Xanthi NN. For this purpose, leaves were mechanically inoculated with treated fabrics and cleaning solutions which would normally be discharged to the sewer system. The detergents Fadex H+ (FH) and Menno Hortisept Clean Plus, as well as the disinfectant Menno Florades (MF), led to an almost complete removal of ToBRFV from contaminated fabrics, corresponding to a reduction in local lesions by 99.94–99.96%. In contrast, common household cleaning products (Spee ActivGel (SAG), Vanish Oxi Action Gel (VO) did not effectively remove the pathogen from the fabric, where the reduction was 45.1% and 89.7%, respectively. In particular, cleaning solutions after the use of household cleaners were highly contaminated with ToBRFV. After a 16-h treatment with the disinfectant MF, infectious ToBRFV was no longer present in VO, FH, and MF cleaning solutions, as demonstrated by extensive bioassays.

We observed the health status of oak trees in a conservation seed orchard for over twenty years, focusing on characteristic virus-suspected symptoms. The orchard was established in 1992 in Kreuztal, North Rhine-Westphalia (Germany) with 1302 seedlings in 186 clusters. The number of seedlings showing chlorotic ringspots and mottle on leaves has fluctuated annually, but has increased from 3.3% to 12.1% in the last 20 years; the number of affected clusters has risen from 8% to 25.9%. A scientific breakthrough was the identification of a novel virus related to members of the genus Emaravirus in diseased oak by high-throughput sequencing (HTS). Screening of the oak seedlings in three consecutive years, using a newly established virus-specific diagnostic reverse transcription polymerase chain reaction (RT-PCR), confirmed the virus infection and revealed a close to 100% association between the observed leaf symptoms and the novel virus. As no other plant virus could be identified in the HTS-datasets, we assume the novel virus is primarily causing the symptoms. To reliably detect the novel virus in oaks, RT-PCR targeting the viral RNA3 or RNA4 should be applied in routine testing of symptomatic leaf tissue. It was obvious that most groups with virus-infected plants cluster, with only five out of the 42 affected groups being offside, not bordering on other affected groups of plants. There was no clear correlation between the detection of the virus and the overall vitality of the seedlings. There was no relation between seedling performance and presence or absence of viral infection. Forecasts on the future growth behavior of these virus-infected oak trees are therefore not possible.

Due to its global spread, easy mechanical transmissibility inside greenhouses, and detrimental effects on marketability, Tomato brown rugose fruit virus (ToBRFV) is considered to be one of the biggest threats to tomato production. Regarding such crop epidemics, it is essential to identify all conceivable transmission routes and to interrupt them with effective decontamination strategies. We analyzed the potential efficacy of reliable shoe sole cleaning in combination with a disinfection measure. For this purpose, first, a suspension test was undertaken that involved applying different disinfectants to an infected plant homogenate. This was followed by a simulated carrier test. Finally, shoe-sole decontamination was tested under practical conditions. The extent of decontamination was determined by bioassays of the infectivity of the initial load remaining after treatment. Thereby, necrotic local lesions on the susceptible indicator plant Nicotiana tabacum cv. Xanthi NN were counted. Recommendations for practical applications, based on suspension or simulated carrier tests, are limited in their applicability, since very short contact times between ToBRFV and disinfectants reduce efficacy. Under practical conditions, the approved disinfectant MENNO Florades was able to achieve complete inactivation of the virus in the disinfection mat following mechanical depletion from the shoe soles.

The tomato brown rugose fruit virus (ToBRFV) causes severe damage to tomato cultivars and has international economic importance. The harmful tobamovirus is easily mechanically transmissible and highly stable. An ongoing cultivation of infected tomato plants may lead to the spread of ToBRFV in and around the production area of the infested tomato farm. We conducted a study in which we collected a representative number of swab samples from various inanimate surfaces in greenhouses, packaging halls, and shared and private accommodations. In addition, numerous fabrics, such as outer clothing, bed linen, and items used by greenhouse workers, were tested. The infectivity of ToBRFV-contaminated surfaces was tested in bioassays using Nicotiana tabacum cv. Xanthi NN and confirmed using DAS-ELISA. The proportion of ToBRFV-contaminated surfaces varied among locations, from 48.7% in greenhouses to 0% in offices with limited access to staff. Samples from shared accommodation and private accommodation were 18.4% and 3.6% ToBRFV positive, respectively. Clothing and protective items were found to be highly contaminated with ToBRFV, and even around the sleeping area, infective ToBRFV was detected in a few apartments. This study provides evidence for the first time on how and where infectious ToBRFV can be spread by humans beyond the production area. To avoid further dissemination, strict hygiene protocols are required to interrupt transmission routes.

After entry of a quarantine/regulated pathogen, infected plants shall be destroyed, and the cultivated area (e.g., greenhouse) shall be disinfected. Therefore, the selection of an effective disinfectant plays an important role. With the availability of different methods for virus quantification, we investigated the application of quantitative ELISA (qELISA), RT-qPCR (reverse transcription-quantitative polymerase chain reaction), and bioassays for the quantification of disinfectant efficacy. Therefore, we estimated the titer reduction in tomato brown rugose fruit virus (ToBRFV), a regulated pathogen, in plant sap and on germ carriers after treatment with MENNO Florades 4% for 16 h. The virus load before and after the treatment was measured with the mentioned methods. The RT-qPCR and qELISA methods showed very low efficacy in the presence of the disinfectant. Although bioassays are time-consuming, need purified particles for establishing the quantification models, and are less sensitive than RT-qPCR, they were able to quantify the differences in virus titer in the presence/absence of disinfectant. Interestingly, the bioassays reached at least the lower limit sensitivity of a qELISA. By being less sensitive to the presence of the disinfectant, bioassays proved to be the only technique for the determination of the disinfectant efficacy against ToBRFV on different germ carriers as well as on virus-infected plant sap.

Los virus que afectan las plantas son de gran importancia en la producción agrícola de Colombia. Diferentes estudios indican que las pérdidas económicas causadas por estos problemas fitosanitarios, podrían evitarse con un mayor conocimiento sobre estos patógenos y mediante un sistema de manejo como guía. Los viveros, productores, comercializadores y consumidores, se beneficiarían de productos de calidad al controlar las fuentes de virus. Los acuerdos de libre comercio han dado lugar a una expansión de la producción agrícola y a la proliferación de cientos de viveros que no han sido objeto de inspección minuciosa por parte del estado. Este artículo presenta los principales virus que afectan dos importantes frutales exóticos de exportación para Colombia, los frutos de pasión (Passiflora sp.) y la uchuva (Physalis peruviana). A su vez, esquematiza lo que sería un programa de producción y certificación de material vegetal sano para los viveros y la creación de un programa nacional de certificación de material, dirigido por el Ministerio de Agricultura y Desarrollo Rural y el Instituto Colombiano Agropecuario (ICA); apoyado por las universidades con carreras agrícolas, centros de investigación y laboratorios fitosanitarios que proporcionarían un sistema de supervisión y control adecuados, para el material vegetal y esquemas de asistencia técnica oportuna para los agricultores. Esta iniciativa interinstitucional también apoyaría la implementación y el ajuste de las resoluciones fitosanitarias del ICA en semillas (R. 2046/2003), material de propagación en frutales (R. 3180/2009) y la resolución recientemente aprobada para el transporte interno de material vegetal (R. 3973/2016). Los productores necesitan acceso a material vegetal sano, para proteger la seguridad alimentaria nacional y mantener una ventaja competitiva en el mercado.

Cherry leaf roll virus (CLRV) was first reported in 1933 in English walnut and sweet cherry. Since then numerous hosts have been recorded revealing its wide natural host range, which includes 17 genera of woody plants and a variety of herbaceous plants. CLRV belongs to the Nepovirus genus, and unlike the majority of other members of this genus, it is not considered to be transmitted by nematodes. However, reliable investigations on nematode transmission are still lacking.

Viroids are of practical importance as the cause of several economically significant infectious diseases. Potato spindle tuber viroid (PSTVd) causes severe yield losses in several crops, because the pathogen spreads fast within the culture. Viroids are small molecules, a few hundred nucleotides long, with a high degree of secondary structure. They do not code for any polypeptides and replicate independently of any associated plant virus. Viroids are readily transmitted by contaminated tools and tables. Furthermore PSTVd is transmitted through the pollen and true seed and can remain its infectious activity in seed for long periods. Vector transmission of PSTVd was reported to occur at low frequency. However, the mechanical transmission is the predominant factor and in this case we discuss the efficient disinfection of tools and tables as a main prophylactic trail to avoid viroid transmission. In previous studies we have tested the efficiency of several disinfectants to eliminate virus contamination. This paper demonstrates the efficient disinfection of MENNO-Florades (Menno-Chemie-GmbH, Norderstedt, Germany. A selection of different concentrations of the disinfectant and various times of incubation were applied in regard to practical use. The tests were confirmed by biological assays using suitable indicator plants, tissue print hybridization, gel electrophoresis and by nucleic acid hybridization. It was shown that PSTVd was eliminated when using the determined combination: 2% of the disinfectant while incubating for one minute or alternative 3%, 30 seconds. The possibility of viroid inactivation by a chemical method of disinfection--while plants are not affected--opens a new perspective to control viroid transmission via tools and tables.

Considering the availability of serological and molecular biological methods, the bioassay has been paled into insignificance, although it is the only experimental method that can be used to demonstrate the infectivity of a virus. We compared goodness-of-fit and predictability power of five models for the quantification of tomato brown rugose fruit virus (ToBRFV) based on local lesion assays: the Kleczkowski model, Furumoto and Mickey models I and II, the Gokhale and Bald model (growth curve model), and the modified Poisson model. For this purpose, mechanical inoculations onto <i>Nicotiana tabacum</i> L. cv. Xanthi nc and <i>N. glutionosa</i> L. with defined virus concentrations were first performed with half-leaf randomization in a Latin square design. Subsequently, models were implemented using Python software and fitted to the number of local lesions. All models could fit to the data for quantifying ToBRFV based on local lesions, among which the modified Poisson model had the best prediction of virus concentration in spike samples based on local lesions, although data of individual indicator plants showed variations. More accurate modeling was obtained from the test plant <i>N. glutinosa</i> than from <i>N. tabacum</i> cv. Xanthi nc. The position of the half-leaves on the test plants had no significant effect on the number of local lesions.
