“…The first report of ToMMV in the pepper fields in Yunnan Province was in 2014 (Li et al, 2014) and is now in the pepper, tomato, and eggplant in other parts of China (Chai et al, 2018;Li et al, 2020). Because ToMMV can cause severe diseases in many crops and its infection rate in vegetable crops is gradually increasing in China (Sui et al, 2017;Nagai et al, 2019;Li et al, 2020), it may become a devastating virus in many vegetable crops in China. We consider that more investigations are needed to identify new viruses so that specific virus resistance can be integrated in the pepper and tomato breeding programs.…”

During pepper and tomato production seasons in 2013–2017, large-scale virus disease surveys were conducted in different regions of Yunnan Province, China. A total of 1,267 pepper and tomato samples with various virus-like symptoms were collected and analyzed for virus infections through dot enzyme-linked immunosorbent assay (dot-ELISA), polymerase chain reaction (PCR), and reverse-transcription (RT)-PCR. The detection results showed that 19 different viruses were present in about 50.9% of the assayed samples, and among these viruses, seven viruses were found in both pepper and tomato samples. Mixed infections with two to three of the 15 identified mixed infection types were found in the pepper samples and 10 identified mixed infection types were found in the tomato samples. Among the infected samples, Tomato spotted wilt orthotospovirus (TSWV) was the most common virus, with a detection rate of about 20.0% followed by Pepper vein yellows virus (PeVYV, 13.0%). This survey revealed for the first time that pepper is a natural host of Tobacco vein distorting virus (TVDV) worldwide and tomato is a natural host of Potato leafroll virus (PLRV) in China. PeVYV, Tobacco mild green mosaic virus (TMGMV) and Wild tomato mosaic virus (WTMV) were first time found in pepper and Tomato mottle mosaic virus (ToMMV) and Chilli veinal mottle virus (ChiVMV) were first time found in tomato in Yunnan Province. Finally, the virus incidences were higher in Kunming, Yuxi, Chuxiong, and Honghe region than other regions.

“…Interception of ToMMV introduction in Australia through infected pepper seeds was made in biosecurity checks (Lovelock et al, 2020), highlighting the importance of preventive measures in preventing virus spread. ToMMV was shown to successfully infect a small portion of ToMV-resistant plants (Sui et al, 2016) but did not successfully infect some cultivars with Tm-2 2 gene, (Nagai et al, 2019). Further assessment is needed to ascertain yield loss and economic impact of ToMMV.…”

Global Advances in Tomato Virome Research: Current Status and the Impact of High-Throughput Sequencing

Viruses cause a big fraction of economically important diseases in major crops, including tomato. In the past decade (2011–2020), many emerging or re-emerging tomato-infecting viruses were reported worldwide. In this period, 45 novel viral species were identified in tomato, 14 of which were discovered using high-throughput sequencing (HTS). In this review, we first discuss the role of HTS in these discoveries and its general impact on tomato virome research. We observed that the rate of tomato virus discovery is accelerating in the past few years due to the use of HTS. However, the extent of the post-discovery characterization of viruses is lagging behind and is greater for economically devastating viruses, such as the recently emerged tomato brown rugose fruit virus. Moreover, many known viruses still cause significant economic damages to tomato production. The review of databases and literature revealed at least 312 virus, satellite virus, or viroid species (in 22 families and 39 genera) associated with tomato, which is likely the highest number recorded for any plant. Among those, here, we summarize the current knowledge on the biology, global distribution, and epidemiology of the most important species. Increasing knowledge on tomato virome and employment of HTS to also study viromes of surrounding wild plants and environmental samples are bringing new insights into the understanding of epidemiology and ecology of tomato-infecting viruses and can, in the future, facilitate virus disease forecasting and prevention of virus disease outbreaks in tomato.

“…However, there is special attention to its underrepresented prevalence due to the lack of serological tests that discriminate it from ToMV (Turina et al 2016 ). ToMMV can infect pepper plants (Nagai et al 2019 ) and overcome resistance to tobamoviruses (Lovelock et al 2020 ). Interestingly, some reports show that the tomato Tm-2 2 gene could mediate resistance against ToMMV (Nagai et al 2019 ).…”

Understanding tobamovirus-plant interactions: implications for breeding resistance to tomato brown rugose fruit virus

et al. 2022

The genus Tobamovirus comprises a group of single-stranded RNA viruses that affect a wide variety of vegetables of economic importance. Tobamoviruses express a series of proteins that interact with the plant’s cellular machinery, allowing viral infection; during incompatible interactions, active defense is mediated by host proteins encoded by resistance genes. The genes conferring viral resistance and tolerance in non-susceptible hosts have been studied for their ability to transfer desired resistance traits to different crops. The N gene from Nicotiana spp., the repertoire of Tm genes in Solanum spp., the L locus from Capsicum spp., and TOM genes are the most studied genetic sequences for understanding resistance to tobamoviruses. Through classical plant breeding and genetic engineering techniques, it has been possible to introgress these resistance genes ( R ) into new species. However, new reports highlight the ability of tobamoviruses to overcome R -mediated defense. One of the most notorious recent cases is the tomato brown rugose fruit virus (ToBRFV). The main characteristic of ToBRFV is its capacity to overcome the resistance mediated by the Tm-2 2 gene, resulting in a limited repertoire of options to combat the virus. To defeat emerging viruses, it is necessary to apply the knowledge from other tobamoviruses-host relationships and use new technologies such as genome-wide association studies (GWAS) to understand and associate the architecture of resistance genes present in the Solanaceae family for the benefit of plant breeding. Although new genomic tools such as CRISPR systems open the possibility of coping with viral diseases, there are no commercial ToBRFV-resistant tomato varieties. Hence, the world’s leading seed suppliers compete to develop and bring these varieties to market.
