“…The known tomato‐infecting begomovirus species in Central America and Mexico include Chino del tomate virus (CdTV) (Paplomatas et al ., 1994; Brown et al ., 2000), Pepper golden mosaic virus (PepGMV) (Torres‐Pacheco et al ., 1996), Pepper huasteco yellow vein virus (PHYVV) (Torres‐Pacheco et al ., 1993), Potato yellow mosaic Panama virus (PYMPV) (Engel et al ., 1998), Tomato chino La Paz virus (ToChLPV) (Holguín‐Peña et al ., 2003), Tomato leaf curl Sinaloa virus (ToLCSinV, tentative species) (Idris & Brown, 1998; Idris et al ., 1999), Tomato mottle virus (ToMoV) (Abouzid et al ., 1992) and Tomato severe leaf curl virus (ToSLCV) (Maxwell et al ., 2002). Many of these viruses also infect other solanaceous species.…”

“…Many of these viruses also infect other solanaceous species. For example, PepGMV has been detected in pepper, tomato, tomatillo and tobacco in Mexico (Torres‐Pacheco et al ., 1996; Paximadis et al ., 1999; Méndez‐Lozano et al ., 2001; Holguín‐Peña et al ., 2003). However, the begomoviruses detected in cucurbits generally differ from those in Solanaceae and include Cucurbit leaf curl virus (CuLCV) (Brown et al ., 2002), Squash yellow mottle virus (SYMoV) (Karkashian et al ., 2002), Squash leaf curl virus (SLCV) (Lazarowitz & Lazdins, 1991), Squash mild leaf curl virus (SMLCV) (Lazarowitz, 1991; Brown et al ., 2002) and Melon chlorotic leaf curl virus (MCLCV) (Brown et al ., 2001a).…”

Genetic diversity and mixed infections of begomoviruses infecting tomato, pepper and cucurbit crops in Nicaragua

Begomoviruses were detected in Nicaraguan fields of tomato ( Lycopersicon esculentum ) and adjacently growing plants of pepper ( Capsicum annuum ), chilli pepper ( C . baccatum ), cushaw ( Cucurbita argyrosperma ) and Mexican fireplant ( Euphorbia heterophylla ) using polymerase chain reaction (PCR) and universal begomovirus primers. All tomato and Mexican fireplant plants showing symptoms were infected with begomoviruses, while only 30 -46% of the pepper, chilli pepper and cushaw plants showing symptoms tested virus-positive. No begomoviruses were found in potato. The virus species were provisionally identified by sequencing 533 bp of the viral coat protein gene ( AV1 ). Tomato severe leaf curl virus (ToSLCV), Tomato leaf curl Sinaloa virus (ToLCSinV) and Pepper golden mosaic virus (PepGMV) were found to infect both tomato and pepper. A new provisional species designated Tomato leaf curl Las Playitas virus (ToLCLPV) was detected in a tomato plant. Squash yellow mottle virus (SYMoV) and PepGMV were found in cucurbits, the latter for the first time in this host. Euphorbia mosaic virus (EuMV) was detected in Mexican fireplant. Sequencing of a larger number of PCR-amplified clones from selected plants revealed intraspecific viral sequence variability, and also multiple begomovirus infections which could represent up to three species in a single tomato or cushaw plant. Phylogenetic grouping of virus sequences did not correlate with the host of origin.

En un invernadero de alta tecnología ubicado en Atlacomulco, Estado de México, se han observado incidencias del 60 al 90% de plantas con síntomas típicos de begomovirus. Los objetivos del presente estudio fueron identificar begomovirus presentes, conocer si se transmiten por semilla, determinar la especie de mosca blanca y si ésta es portadora de los virus. Hojas de plantas adultas con síntomas se analizaron con oligonucleótidos universales para begomovirus. Semillas de frutos de plantas positivas a begomovirus se sembraron en almácigos para obtener plántulas, éstas y parte de las semillas se analizaron por PCR para detectar begomovirus. Adultos de mosca blanca se analizaron con oligonucleótidos específicos del gen mitocondrial de la subunidad I del citocromo C oxidasa y con oligonucleótidos universales para begomovirus. Las secuencias de los productos obtenidos por PCR de plantas con síntomas tuvieron una similitud de 99% con el <em>Tomato severe leaf curl virus</em> (ToSLCV). No se detectaron begomovirus en semilla y plántula. Las secuencias obtenidas por PCR de mosca blanca en el invernadero tuvieron 99% de similitud con <em>Bemisia tabaci</em> y los individuos analizados fueron portadores del ToSLCV. Este es el primer reporte del ToSLCV asociado a tomate en invernadero en México.

“…The natural crop-hosts of PHYVV include pepper (Capsicum annum L.), tomato (Solanum lycopersicum) and tomatillo (Physalis ixocarpa). Among wild species PHYVV is infecting Nicotiana glauca, Solanum elaeagnifolium, Solanum nigrescens and S. rostrarum(Melendrez-Bojorquez et al, 2016;Méndez-Lozano and Rivera- Bustamante, 2001) ToSLCV is known to infect tomato among cultivated species and Datura stramonium among weeds(Holguín-Peña, 2003). TYLCV has a large host range including species in many families (Amaranthaceae, Chenopodiaceae, Compositae,…”

The European Commission requested the EFSA Panel on Plant Health to evaluate the probability of entry of pests (likelihood of pest freedom at entry), including both, regulated and non‐regulated pests, associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Guatemala. The relevance of any pest for this opinion was based on evidence following defined criteria, based on the methodology used for high‐risk plants adapted for the specificity of this assessment. Nineteen EU regulated pests (Bemisia tabaci, pepper golden mosaic virus, pepper huasteco yellow vein virus, tomato severe leaf curl virus, tomato yellow leaf curl virus, tomato spotted wilt virus, Liriomyza huidobrensis, Liriomyza sativae, Liriomyza trifolii, Bactericera cockerelli, Eotetranichus lewisi, Epitrix subcrinita, Epitrix cucumeris, Helicoverpa zea, Chloridea virescens, Spodoptera ornithogalli, Ralstonia solanacearum, Ralstonia pseudosolanacearum, Xanthomonas vesicatoria) and one EU non‐regulated (Phenacoccus solenopsis) pest fulfilled all relevant criteria and were selected for further evaluation. For these pests, the risk mitigation measures proposed in the technical dossier from Guatemala were evaluated taking into account the possible limiting factors, and an expert judgement is given on the likelihood of pest freedom taking into consideration the risk mitigation measures acting on the pest, including uncertainties associated with the assessment. The limited and partially conflicting information provided in the dossier contributes to the wide estimates of pest freedom. The estimated degree of pest freedom varies among the pests evaluated, with Ralstonia spp. (R. solanacearum and R. pseudosolanacearum) being the pest most frequently expected on the imported cuttings. The expert knowledge elicitation indicated, with 95% certainty, that between 9916 and 10,000 bags containing unrooted cuttings per 10,000 would be free of Ralstonia spp.
