“…Thus, at any given geographical site across Brazil, different combinations of viruses are expected to predominate. Indeed, previous surveys carried out in the states of São Paulo (59,74), Minas Gerais/Rio de Janeiro/Espírito Santo (24), Goiás (21), and Bahia/Pernambuco (23) indicated the prevalence of ToYVSV, ToCMoV, ToSRV, and ToMoLCV, respectively. These differences could reflect local variations in noncultivated host distributions at the sampling sites or the capacity of local, non-biotype B vector populations to transmit particular virus species.…”

eThe incidence of begomovirus infections in crop plants sharply increased in Brazil during the 1990s following the introduction of the invasive B biotype of the whitefly vector, Bemisia tabaci. It is believed that this biotype transmitted begomoviruses from noncultivated plants to crop species with greater efficiency than indigenous B. tabaci biotypes. Either through rapid host adaptation or selection pressure in genetically diverse populations of noncultivated hosts, over the past 20 years various previously unknown begomovirus species have became progressively more prevalent in cultivated species such as tomato. Here we assess the genetic structure of begomovirus populations infecting tomatoes and noncultivated hosts in southeastern Brazil. Between 2005 and 2010, we sampled and sequenced 126 DNA-A and 58 DNA-B full-length begomovirus components. We detected nine begomovirus species in tomatoes and eight in the noncultivated host samples, with four species common to both tomatoes and noncultivated hosts. Like many begomoviruses, most species are obvious interspecies recombinants. Furthermore, species identified in tomato have probable parental viruses from noncultivated hosts. While the population structures of five well-sampled viral species all displayed geographical subdivision, a noncultivated host-infecting virus was more genetically variable than the four predominantly tomato-infecting viruses.

“…Thus, the maximum retention of 14 days has been measured after a six-hour acquisition period [ 29 ]. The retention values of 20 days have also been reported for Chino del tomato virus (CdTV) and tomato yellow vein streak virus (ToYVSV) [ 30 , 31 ], and life-long retention in the vector was reported for tomato yellow leaf curl Thailand virus (TYLCTHV) [ 32 ]. Comparisons of the transmission of ToLCNDV-ES and other begomoviruses should be done with caution.…”

The tomato leaf curl New Delhi virus (ToLCNDV) is a bipartite, single-stranded begomovirus that was first identified in India in 1995 affecting solanaceous crops. A different strain, named ToLCNDV-ES, was introduced in Spain in 2012 and causes severe symptoms in zucchini crops. Virus transmission experiments with the whitefly Bemisia tabaci, were used to compare the transmission parameters in zucchini and tomato plants. The minimum acquisition access period and inoculation access period of ToLCNDV-ES transmission was similar in zucchini and tomato. However, the transmission efficiency was significantly higher in zucchini (96%) compared to tomato (2%). The maximum retention of the virus in the vector was 16 days. B. tabaci feeding on, or recently emerged from infected zucchini plants, accumulated more virus than those from infected tomato, as determined by real-time PCR. A total of 20% of B. tabaci that were recently emerged from infected zucchini, and none from infected tomato, were able to transmit the virus to virus-free zucchini. The results may explain the different incidences of ToLCNDV-ES in zucchini and tomato crops in Spain. But they are also relevant for ToLCNDV-ES management of crops and the role of the trade and transport of infected plant material, when small-sized immature stages of B. tabaci could be a source of infection.

“…The inoculation threshold of Rice tungro‐associated viruses (bacilliform and isometric) by Nephotettix virescens is 10 min . Whitefly B. tabaci (MEAM1 species) transmits Tomato yellow vein streak virus and Sweet potato leaf curl virus in as little as 10 min and 15 min, respectively . The minimum inoculation threshold of Faba bean necrotic yellows virus by its aphid vectors, Aphis craccivora and Acyrthosiphon pisum , ranges from 5 to 15 min .…”

Rice virus release from the planthopper salivary gland is independent of plant tissue recognition by the stylet

BackgroundThe transmission of plant viruses by arthropod vectors is closely related to feeding behavior. For persistently transmitted viruses, virus release means that virus moves through the salivary gland microvillus barriers of insects into plant via the stylet. However, whether virus release is dependent on plant tissue and component recognition by the stylet is unclear.ResultsIn this study, the small brown planthopper (SBPH) and two rice viruses transmitted by it were used as a model to explore this question. After the viruliferous insects penetrated a stretched membrane without plant tissue structure and ingested liquid food (rice sap, nutrient solution or water), both viruses were detected in the liquid food after only a 6 min inoculation access period, suggesting that the viruses were released from SBPH salivary gland independent of plant tissue and component recognition by the stylet. In subsequent electrical penetration graph (EPG) analysis, N4a‐like and N4b‐like waveforms, similar to N4a (phloem salivation before ingestion) and N4b (sieve element ingestion), were observed during SBPH penetrating the membrane, exhibiting normal feeding activity of planthopper on membrane, which further demonstrated that virus release from salivary gland was along with feeding activity, without the stylet sensing plant tissue. EPG analysis and identification of salivary proteins indicated more active feeding behavior and efficient salivation in viruliferous planthoppers.ConclusionThese results suggest that the rice virus is released from insect salivary gland independent of plant tissue and component recognition by the stylet, and the simple virus release mode facilitates virus transmission by vectors. © 2020 Society of Chemical Industry
