“…2 ). Pairwise comparisons of the N, NSs and RdRp protein sequences showed that TCSV-DR is most closely related to the TCSV isolates reported in cultivated and ornamental plants [ 17 , 18 ]. The NSm and the glycoprotein precursor protein sequences analysis revealed TCSV-DR closest to the unique reassortant isolate formed between TCSV and GRSV (S GRSV , M TCSV and L GRSV ) (Fig.…”

The Tomato chlorotic spot virus (TCSV) was first reported in the 1980s, having its occurrence limited to Brazil and Argentina. Due to an apparent mild severity in the past, molecular studies concerning TCSV were neglected. However, TCSV has disseminated over the USA and Caribbean countries. In Dominican Republic TCSV has been recently reported on important cultivated crops such as pepper and beans. In this work, we provide the first complete genome of a TCSV isolate from symptomatic plants in Dominican Republic, which was obtained by high-throughput sequencing. In addition, three dsRNA viruses from different virus families were identified coinfecting these plants Bell pepper endornavirus (BPEV), Southern tomato virus (STV) and Pepper cryptic virus 2 (PCV-2). Phylogenetic analysis showed that the Dominican Republic TCSV isolate has a close relationship with other TCSV isolates and a reassortant isolate between TCSV and Groundnut ringspot virus (GRSV), all found in USA. BPEV, STV and PCV-2 isolates from Dominican Republic were close related to corresponding American isolates. The possible biological implications of these virus-mixed infections are discussed.

“…Interestingly, Melon yellow spot virus (MYSV), formerly reported only in Asia, has for the first time been found outside Asia, in Ecuador (94). Furthermore, in Florida in 2012 (66), the first occurrence of a natural interspecific reassortant Groundnut ringspot virus (GRSV)-Tomato chlorotic spot virus (TCSV) in tomato fields has been reported (144) and its parental TCSV species identified. Another study performed with a number of TSWV isolates showed that reassortment among isolates within a species seems to be a common evolutionary strategy (136), and, in one case, a resistance-breaking (RB) isolate was shown to originate through reassortment (73).…”

During the past three decades, the economic impact of tospoviruses has increased, causing high yield losses in a variety of crops and ornamentals. Owing to the difficulty in combating thrips vectors with insecticides, the best way to limit/prevent tospovirus-induced diseases involves a management strategy that includes virus resistance. This review briefly presents current tospovirus taxonomy, diversity, molecular biology, and cytopathology as an introduction to a more extensive description of the two main resistance genes employed against tospoviruses: the Sw5 gene in tomato and the Tsw in pepper. Natural and experimental resistance-breaking (RB) isolates allowed the identification of the viral avirulence protein triggering each of the two resistance gene products; epidemiology of RB isolates is discussed to reinforce the need for allelic variants and the need to search for new/alternative resistance genes. Ongoing efforts for alternative resistance strategies are described not only for Tomato spotted wilt virus (TSWV) in pepper and tomato but also for other vegetable crops heavily impacted by tospoviruses.

“…Subsequently, TCSV was isolated from sweet peppers, potatoes, endives, celery, lisianthus and various weeds with mosaic, necrosis, chlorotic or stunting symptoms in Argentina and Brazil (Boiteux et al ., ; Gracia et al ., ; Colariccio et al ., ; Dal Bio et al ., ; Eiras et al ., ), and from outbreaks on lettuce and gilo in Brazil (Colariccio et al ., ; Rabelo et al ., ). In the USA, TCSV was first detected from tomatoes in south Florida in 2012 (Londoño et al ., ), and then from lettuce, impatiens and peppers (Webster et al ., ). In Puerto Rico, TCSV was also found from tomatoes, peppers, jimsonweed ( Datura stramonium ), and lettuce in 2013 (Estévez de Jensen et al ., ; Estévez de Jensen & Adkins, ).…”

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.
