“…The host range of ToCV extends, in addition to tomato, to other solanaceous hosts including pepper (Lozano et al, 2003), potato (Fortes et al, 2012), and tomatillo (Trenado et al, 2007). Several weed species can also harbor ToCV (Font et al, 2004; Wintermantel and Wisler, 2006), and the presence of weed hosts near production areas can provide an alternate host for the virus between cropping seasons, as well as providing an acquisition source for whitefly vectors that can carry the virus back to cultivated hosts.…”

The genus Crinivirus includes the whitefly-transmitted members of the family Closteroviridae. Whitefly-transmitted viruses have emerged as a major problem for world agriculture and are responsible for diseases that lead to losses measured in the billions of dollars annually. Criniviruses emerged as a major agricultural threat at the end of the twentieth century with the establishment and naturalization of their whitefly vectors, members of the genera Trialeurodes and Bemisia, in temperate climates around the globe. Several criniviruses cause significant diseases in single infections whereas others remain asymptomatic and only cause disease when found in mixed infections with other viruses. Characterization of the majority of criniviruses has been done in the last 20 years and this article provides a detailed review on the epidemiology of this important group of viruses.

“…Some of these viruses are contact and seed-transmitted, including Tomato mosaic virus (ToMV, [8]), Pepper mild mottle virus (PMMoV, [9]) and Tobacco mild green mosaic virus (TMGMV, [10]), and some are aphid transmitted, including Cucumber mosaic virus (CMV, [11]) and Potato virus Y (PVY, [11]), and have been present in the region and crop species for many decades. Others are considered emerging viruses and include the western flower thrips Frankliniella occidentalis-transmitted Tomato spotted wilt tospovirus (TSWV, [12]), Bemisia tabaci-transmitted Tomato chlorosis crinivirus (ToCV, [13]) and the pollen-transmitted Parietaria mottle ilarvirus (PMoV, [14,15]). …”

The Influence of Crop Habitat and Control Strategies on Pepper Viruses in Andalusia (Spain)

et al. 2016

Andalusia, southern Spain, is a major horticultural production region within the Mediterranean, where over 10,000 ha are dedicated to the production of pepper (Capsicum annuum L.). Approximately two-thirds of the area dedicated to this crop is in a greenhouse and the remaining one-third is comprised of open field crops. Using pepper as a model, we identified and compared the major diseases caused by viruses in the different geographic regions and agronomic systems within the region. Pepper crops in plastic-covered greenhouses were predominantly associated with arthropod-transmitted virus diseases, such as TSWV. CMV was predominant in provinces located inland, and PMoV was found independent of the agrosystem, disease control methods, or geographic location.

“…ToCV infections on sweet pepper have been reported from Spain (Lozano et al , ), Brazil (Barbosa et al , ), Costa Rica (Vargas et al , ), Tunisia (Gharsallah et al , ) and Saudi Arabia (Shakeel et al , ). The effect of the disease on sweet pepper has been revealed by controlled experiments using B. tabaci as a vector (Fortes et al , ). These experiments showed that varieties of the three basic types of pepper grown in the Mediterranean basin (Italian, California and Lamuyo) are efficiently infected by the virus.…”

Summary Tomato chlorosis virus (ToCV) causes an important disease that primarily affects tomato, although it has been found infecting other economically important vegetable crops and a wide range of wild plants. First described in Florida (USA) and associated with a ‘yellow leaf disorder’ in the mid‐1990s, ToCV has been found in 35 countries and territories to date, constituting a paradigmatic example of an emergent plant pathogen. ToCV is transmitted semipersistently by whiteflies (Hemiptera: Aleyrodidae) belonging to the genera Bemisia and Trialeurodes . Whitefly transmission is highly efficient and cases of 100% infection are frequently observed in the field. To date, no resistant or tolerant tomato plants are commercially available and the control of the disease relies primarily on the control of the insect vector. Taxonomy Tomato chlorosis virus is one of the 14 accepted species in the genus Crinivirus , one of the four genera in the family Closteroviridae of plant viruses. Virion and genome properties The genome of ToCV is composed of two molecules of single‐stranded positive‐sense RNA, named RNA1 and RNA2, separately encapsidated in long, flexuous, rod‐like virions. As has been shown for other closterovirids, ToCV virions are believed to have a bipolar structure. RNA1 contains four open reading frames (ORFs) encoding proteins associated with virus replication and suppression of gene silencing, whereas RNA2 contains nine ORFs encoding proteins putatively involved in encapsidation, cell‐to‐cell movement, gene silencing suppression and whitefly transmission. Host range In addition to tomato, ToCV has been found to infect 84 dicot plant species belonging to 25 botanical families, including economically important crops. Transmission Like all species within the genus Crinivirus , ToCV is semipersistently transmitted by whiteflies, being one of only two criniviruses transmitted by members of the genera Bemisia and Trialeurodes . Disease symptoms Tomato ‘yellow leaf disorder’ syndrome includes interveinal yellowing and thickening of leaves. Symptoms first develop on lower leaves and then advance towards the upper part of the plant. Bronzing and necrosis of the older leaves are accompanied by a decline in vigour and reduction in fruit yield. In other hosts the most common symptoms include interveinal chlorosis and mild yellowing on older leaves. Control Control of the disease caused by ToCV is based on the use of healthy seedlings for transplanting, limiting accessibility of alternate host plants that can serve as virus reservoirs and the spraying of insecticides for vector control. Although several wild tomato species have been sh...
