“…The TMGMV isolate NBHP (MW012408) was closely related to the isolate CaJO from Jordan ( Figure 6 D). In the case of AYVCNV, we previously reported the assembled genome sequence as Ageratum yellow vein virus (AYVV) isolate BaoLoc [ 10 ]. However, a BLASTN search against a nucleotide database using the same identical genome sequence showed that the nearly complete genome for AYVV isolate BaoLoc showed strong genetic relationship with other known isolates from China ( Figure 6 E).…”

“…Among the viruses infecting solanaceous vegetables, cucumber mosaic virus (CMV) in the genus Cucumovirus might be the most important virus for plants in the family Solanceae [ 9 ]. Tomato spotted wilt virus (TSWV) in the genus Tospovirus is a recently emerging plant virus that causes serious viral diseases in a wide range of important plants, including pepper and tomato [ 10 ]. In addition, tomato yellow leaf curl virus (TYLCV) in the genus Begomovirus causes severe damage on tomato cultures [ 11 ].…”

Tomato (Lycopersicum esculentum L.) and pepper (Capsicum annuum L.) plants belonging to the family Solanaceae are cultivated worldwide. The rapid development of next-generation sequencing (NGS) technology facilitates the identification of viruses and viroids infecting plants. In this study, we carried out metatranscriptomics using RNA sequencing followed by bioinformatics analyses to identify viruses and viroids infecting tomato and pepper plants in Vietnam. We prepared a total of 16 libraries, including eight tomato and eight pepper libraries derived from different geographical regions in Vietnam. We identified a total of 602 virus-associated contigs, which were assigned to 18 different virus species belonging to nine different viral genera. We identified 13 different viruses and two viroids infecting tomato plants and 12 viruses and two viroids infecting pepper plants with viruses as dominantly observed pathogens. Our results showed that multiple infection of different viral pathogens was common in both plants. Moreover, geographical region and host plant were two major factors to determine viral populations. Taken together, our results provide the comprehensive overview of viral pathogens infecting two important plants in the family Solanaceae grown in Vietnam.

“…In the latest 20 years, TSWV has become widespread throughout most of the states in the USA (Groves et al ., ; Holcomb et al ., ; Díaz‐Pérez & Pappu, ; Holcomb & Valverde, ; Momol et al ., ; Adkins et al ., ; Whitfield et al ., ; Mullis et al ., ; Yang et al ., ; Adkins & Baker, ; Mullis et al ., ; Nischwitz et al ., ,b; Baker et al ., ; Baker et al ., ; Barkley et al ., ; Crosslin et al ., ) causing significant economic losses (Pearce, ). More recently, TSWV was isolated from Stevia rebaudiana and tomatoes with the Sw‐5 orthotospovirus‐resistance gene in Carolina (Koehler et al ., ; Batuman et al ., ). TSWV was found in a commercial chrysanthemum field of Mexico infesting several weeds including Taraxacum officinale , Bidens sp., Reseda luteola , Mirabilis jalapa being transmitted by F. occidentalis (Martinez et al ., ).…”

Western flower thrip, Frankliniella occidentalis (Pergande), is among the most economically important agricultural pests globally, attacking a wide range of vegetable and horticultural crops. In addition to causing extensive crop damage, the species is notorious for vectoring destructive plant viruses, mainly belonging to the genera Orthotospovirus, Ilarvirus, Alphacarmovirus and Machlomovirus. Once infected by orthotospoviruses, thrips can remain virulent throughout their lifespan and continue transmitting viruses to host plants when and wherever they feed. These irruptive viral outbreaks in crops will permanently disrupt functional integrated pest management systems, and typically require a remedial treatment involving insecticides, contributing to further development of insecticide resistance. To mitigate against this continuing cycle, the most effective management is early and comprehensive surveillance of the pest species and recognition of plant viruses in the field. This review provides information on the pest status of F. occidentalis, discusses the current global status of the viruses vectored by this thrip species, examines the mechanisms involved in transmitting virus-induced diseases by thrips, and reviews different management strategies, highlighting the potential management tactics developed for various cropping systems. The early surveillance and the utilization of potential methods for control of both F. occidentalis and viruses are proposed.

“…The use of pepper and tomato resistant cultivars has reduced the damage caused by tospovirus‐induced diseases. However, the continuous employment of these resistant cultivars has resulted in the emergence of resistance‐breaking (RB) isolates (Boiteux & Nagata, ; Cho et al , ; Latham & Jones, ; Roselló et al , ; Roggero et al , ; Aramburu & Martí, ; Thomas‐Carrol & Jones, ; Ciuffo et al , ; Gordillo et al , ; Deligoz et al , ; Álmasi et al , ; Batuman et al , ; Jiang et al , ). Therefore, two types of TSWV isolates have been defined: resistance‐inducing isolates (RI), which trigger a hypersensitivity reaction (HR) and induce resistance; and resistance‐breaking isolates (RB), which are capable of infecting resistant cultivars and therefore of breaking host resistance.…”

Biological and molecular characterization of tomato spotted wilt virus (TSWV) resistance‐breaking isolates from Argentina

Tomato spotted wilt virus (TSWV) has been present in Argentina since 1938 and had limited sweet pepper and tomato production until the introduction of resistant cultivars bearing Tsw and Sw‐5b genes. However, the wide use of TSWV‐resistant pepper plants in La Plata Horticultural Belt (LPHB) triggered the emergence of resistance‐breaking isolates (RB), increasing the economic impact of TSWV in pepper. This work characterized 11 natural RB pepper isolates from LPHB that have overcome the Tsw resistance gene in Capsicum sp. but are unable to break the Sw‐5b‐mediated resistance in tomato. Phylogenetic analysis of the N gene showed that the LPHB isolates are most closely related to isolates from Asia, indicating that Argentine TSWV isolates might have emerged from the Asian continent. The NSs sequence analysis reinforces the hypothesis that the appearance of an RB phenotype is a consequence of a number of different single amino acid substitutions spread along the NSs gene that lead to multiple independent evolutionary events. These results provide information on the current situation of the tospovirus–pepper/tomato pathosystems in LPHB, which represents a fundamental prerequisite to include these RB isolates in future screening programmes in order to select new and durable sources of resistance to TSWV in pepper.
