“…Their rod-shaped particles provide protection of their single-stranded positive-sense RNA genomes (Figure 1) and are extremely stable. The stability of tobamovirus virions makes disinfection of agricultural tools and growth facilities difficult, and it enables infectious tobamovirus inoculum to persist in both liquid and frozen water, in soil, within dead plant material and tobacco products, as well as on the clothing of agricultural workers [4,7,8].…”

Tobacco mosaic virus (TMV) was the first virus to be studied in detail and for many years TMV and other tobamoviruses, particularly tomato mosaic virus (ToMV) and tobamoviruses infecting pepper (Capsicum spp.), were serious crop pathogens. By the end of the twentieth and for the first decade of the twenty-first century tobamoviruses were under some degree of control due to introgression of resistance genes into commercial tomato and pepper lines. However, tobamoviruses remained as important models for molecular biology, biotechnology and bio-nanotechnology. Recently, tobamoviruses have again become serious crop pathogens due to the advent of tomato brown rugose fruit virus, which overcomes tomato resistance against TMV and ToMV, and the slow but apparently inexorable worldwide spread of cucumber green mottle mosaic virus, which threatens all cucurbit crops. This review discusses a range of mainly molecular biology-based approaches for protecting crops against tobamoviruses. These include cross-protection (using mild tobamovirus strains to ‘immunize’ plants against severe strains), expressing viral gene products in transgenic plants to inhibit the viral infection cycle, inducing RNA silencing against tobamoviruses by expressing virus-derived RNA sequences in planta or by direct application of double-stranded RNA molecules to non-engineered plants, gene editing of host susceptibility factors, and the transfer and optimization of natural resistance genes.

“…Drastic diagnostic, quarantine and eradication measures have prevented the spread of PPV within the US, but such measures are not always successful, as the spread of Banana bunchy top virus (BBTV) among banana producing countries shows (Qazi, 2016). The propagation and distribution of virus infected plant material has made humans into the "superspreaders" of plant viruses (Ranawaka et al, 2020), a title that was previously reserved for their native vectors. The most common plant virus transmission vectors are phloem-sucking insects like aphids, whiteflies and thrips, but nematodes, mites, fungi and zoosporic endoparasites have also been described to transmit viruses (Dietzgen et al, 2016, Figure 1B).…”

Viruses exist in intimate relationships with the organisms they are infecting and are just as dependent on compatibility with their host’s cellular components as they are on subverting them. During any virus infection, the cells are flooded with foreign nucleic acids (DNA and/or RNA) and have learned to recognize, disarm, or eliminate them. In turn, viruses have evolved to use the cellular transcription and RNA regulatory machinery for their own benefit. Cytoplasmic RNA granules, namely Processing bodies (PBs) and Stress granules (SGs) are at the forefront of RNA regulation as they contain and store untranslated RNA and are responsive in number, size, and composition to various stresses, including virus infection. For this thesis, we have explored the role of Arabidopsis thaliana RNA granules during infection with the pararetrovirus Cauliflower mosaic virus (CaMV). We show that PB components aid virus accumulation through shielding of the viral RNA from the antiviral RNA silencing machinery (Paper I). In addition, we find that the cytoplasmic viral replication factory contains several RNA granule proteins during infection, including both, PB components and SG components. Opposite to PBs, SGs are likely antiviral and CaMV subverts their biogenesis through its multifunctional protein P6 (Paper II). In an effort to uncover novel disease determinants, we explore the variation of CaMV disease in naturally occurring populations of Arabidopsis thaliana and uncover the importance of the plant hormone abscisic acid and its homeostasis for CaMV infection, as well as a novel CaMV susceptibility factor, the ABA synthesis gene NCED9 (Paper III).

“…In the case of viral diseases, they are responsible for important losses, which in terms of economic impact has been estimated at more than USD 30 billion per year [25,26,174,175]. Such impact is scaling rapidly due to agriculture practices (monoculture), changes in vector populations caused by global warming, and direct human intervention in virus spread [25,27,[175][176][177][178][179][180][181]. In that sense, nearly half of emerging and re-emerging plant diseases are caused by viruses, forecasting an amplified global economic impact in the near future due to altered temperature and weather patterns.…”

Trees and herbs that produce fruits represent the most valuable agricultural food commodities in the world. However, the yield of these crops is not fully achieved due to biotic factors such as bacteria, fungi, and viruses. Viruses are capable of causing alterations in plant growth and development, thereby impacting the yield of their hosts significantly. In this work, we first compiled the world′s most comprehensive list of known edible fruits that fits our definition. Then, plant viruses infecting those trees and herbs that produce fruits with commercial importance in the global market were identified. The identified plant viruses belong to 30 families, most of them containing single-stranded RNA genomes. Importantly, we show the overall picture of the host range for some virus families following an evolutionary approach. Further, the current knowledge about plant-virus interactions, focusing on the main disorders they cause, as well as yield losses, is summarized. Additionally, since accurate diagnosis methods are of pivotal importance for viral diseases control, the current and emerging technologies for the detection of these plant pathogens are described. Finally, the most promising strategies employed to control viral diseases in the field are presented, focusing on solutions that are long-lasting.
