Résumé :

Investigating a virus’s host range and cross-infection is important for better understanding the epidemiology and emergence of viruses. Previously, our research group discovered a natural infection of a plant RNA virus, cumber mosaic virus (genus Cucumovirus, family Bromoviridae), in a plant pathogenic basidiomycetous fungus, Rhizoctonia solani, isolated from a potato plant grown in the field. Here, we further extended the study to investigate whether similar cross-infection of plant viruses occurs widely in plant-associated fungi in natural conditions. Various vegetable plants such as spinach, leaf mustard, radish, celery, and other vegetables that showed typical virus-like diseases were collected from the fields in Shandong Province, China. High-throughput sequencing revealed that at least 11 known RNA viruses belonging to different genera, including Potyvirus, Fabavirus, Polerovirus, Waikavirus, and Cucumovirus, along with novel virus candidates belonging to other virus genera, infected or associated with the collected vegetable plants, and most of the leaf samples contained multiple plant viruses. A large number of filamentous fungal strains were isolated from the vegetable leaf samples and subjected to screening for the presence of plant viruses. RT-PCR and Sanger sequencing of the PCR products revealed that among the 169 fungal strains tested, around 50% were carrying plant viruses, and many of the strains harbored multiple plant viruses. The plant viruses detected in the fungal isolates were diverse (10 virus species) and not limited to particular virus genera. However, after prolonged maintenance of the fungal culture in the laboratory, many of the fungal strains have lost the virus. Sequencing of the fungal DNA indicated that most of the fungal strains harboring plant viruses were related to plant pathogenic and/or endophytic fungi belonging to the genera Alternaria, Lecanicillium, and Sarocladium. These observations suggest that the nonpersistent acquisition of plant viruses by fungi may commonly occur in nature. Our findings highlight a possible role for fungi in the life cycle, spread, and evolution of plant viruses.

Résumé :

The stability of hybrid plant viruses that might arise by recombination in transgenic plants was examined using hybrid viruses derived from the viral expression vectors potato virus X (PVX) and tobacco rattle virus (TRV). The potato virus Y (PVY) NIb and HCPro open reading frames (ORFs) were introduced into PVX to generate PVX-NIb and PVX-HCPro, while the PVY NIb ORF was introduced into a vector derived from TRV RNA2 to generate TRV-NIb. All three viruses were unstable and most of the progeny viruses had lost the inserted sequences between 2 and 4 weeks post-inoculation. There was some variation in the rate of loss of part or all of the inserted sequence and the number of plants containing the deleted viruses, depending on the sequence, the host (Nicotiana tabacum vs Nicotiana benthamiana) or the vector, although none of these factors was associated consistently with the preferential loss of the inserted sequences. PVX-NIb was unable to accumulate in NIb-transgenic tobacco resistant to infection by PVY and also showed loss of the NIb insert from PVX-NIb in some NIb-transgenic tobacco plants susceptible to infection by PVY. These data indicate that such hybrid viruses, formed in resistant transgenic plants from a transgene and an unrelated virus, would be at a selective disadvantage, first by being targeted by the resistance mechanism and second by not being competitive with the parental virus.

Résumé :

The vast majority of well-characterized eukaryotic viruses are those that cause acute or chronic infections in humans and domestic plants and animals. However, asymptomatic persistent viruses have been described in animals, and are thought to be sources for emerging acute viruses. Although not previously described in these terms, there are also many viruses of plants that maintain a persistent lifestyle. They have been largely ignored because they do not generally cause disease. The persistent viruses in plants belong to the family Partitiviridae or the genus Endornavirus . These groups also have members that infect fungi. Phylogenetic analysis of the partitivirus RNA-dependent RNA polymerase genes suggests that these viruses have been transmitted between plants and fungi. Additional families of viruses traditionally thought to be fungal viruses are also found frequently in plants, and may represent a similar scenario of persistent lifestyles, and some acute or chronic viruses of crop plants may maintain a persistent lifestyle in wild plants. Persistent, chronic and acute lifestyles of plant viruses are contrasted from both a functional and evolutionary perspective, and the potential role of these lifestyles in host evolution is discussed.

Résumé :

Abstract Plant viruses are a threat to a sustainable economy because they cause economic losses in yields. The epidemiology of plant viruses is of particular interest because of their dynamic spread by insect vectors and their transmission by seeds. The speed and direction of viral evolution are determined by the selective environment in which they are found. Knowledge of the ecology of plant viruses is critical to the transmission of many plant viruses. Accurate and timely detection of plant viruses is an essential part of their control. Rapid climate change and the globalization of trade through free trade agreements encourage the transmission of vectors and viruses from country to country. Another factor affecting the emergence of viruses is the cultivation of monocultures with low genetic diversity a nd high plant density. Trade in plant material (germplasm and living plants) also cause the emergence of new viruses. Viruses have a fast adaptation and development in a new environment. Aphids are the most widespread and important vectors of plant viruses. Myzus persicae transmits more than 100 different plant viruses. In nature plant viruses are transmitted also by nematodes, fungi, mites, leafhoppers, whiteflies, beetles, and planthoppers. The symptoms of viral diseases are very diverse and are often confused with symptoms of abiotic stress. Control of viral diseases is based on two strategies: i) immunization (genetic resistance acquired by plant transformation, breeding, or cross-protection), ii) prophylaxis to limit viruses (removal of infected plants and control of their vectors). For management, we rely on quick and accurate identification of the disease.

Résumé :

Plant viruses cause severe diseases leading to enormous crop loss. The present day viral researches of economic plants are centered on identification of virus, molecular characterization and management of viral discases. Till date more than thousand viruses have been classified into several families. It is desirable to know about the different virus families along with their type genus and/or important genus. But due to an enormous volume of literature published on this aspect, it becomes difficult to study all of them. Hence the present review has highlighted the salient features of the major plant viruses which have been classified at the family level. Most of the virus families have been discussed with important/type genus of each family. Some viruses which could not be placed in any family have been grouped as 'no family". Importance of molecular data, immunological data and data on protein configuration of coat proteins along with bioinformatics and its predictive power have been highlighted.

Résumé :

Plant RNA viruses encode essential viral proteins that depend on the host translation machinery for their expression. However, genomic RNAs of most plant RNA viruses lack the classical characteristics of eukaryotic cellular mRNAs, such as mono-cistron, 5′ cap structure, and 3′ polyadenylation. To adapt and utilize the eukaryotic translation machinery, plant RNA viruses have evolved a variety of translation strategies such as cap-independent translation, translation recoding on initiation and termination sites, and post-translation processes. This review focuses on advances in cap-independent translation and translation recoding in plant viruses.

Résumé :

Plant viruses use cellular factors and resources to replicate and move. Plants respond to viral infection by several mechanisms, including innate immunity, autophagy, and gene silencing, that viruses must evade or suppress. Thus, the establishment of infection is genetically determined by the availability of host factors necessary for virus replication and movement and by the balance between plant defense and viral suppression of defense responses. Host factors may have antiviral or proviral activities. Proviral factors condition susceptibility to viruses by participating in processes essential to the virus. Here, we review current advances in the identification and characterization of host factors that condition susceptibility to plant viruses. Host factors with proviral activity have been identified for all parts of the virus infection cycle: viral RNA translation, viral replication complex formation, accumulation or activity of virus replication proteins, virus movement, and virion assembly. These factors could be targets of gene editing to engineer resistance to plant viruses.

Résumé :

Plant RNA viruses are one of the most destructive pathogens that cause a significant loss in crop production worldwide. They have evolved with high genetic diversity and adaptability due to the short replication cycle and high mutation rate during genome replication, which are characteristics of RNA viruses. Plant RNA viruses exist as quasispecies with high genetic diversity; thereby, a rapid population transition with new fitness can occur due to selective pressure resulting from environmental changes. Plant resistance can act as selective pressure and affect the fitness of the virus, which may lead to the emergence of resistance-breaking variants. In this paper, we introduced the evolutionary perspectives of plant RNA viruses and the driving forces in their evolution. Based on this, we discussed the mechanism of the emergence of variant viruses that overcome plant resistance. In addition, strategies for deploying plant resistance to viral diseases and improving resistance durability were discussed.

Résumé :

Abstract Molecular engineering of plant immunity to confer resistance against plant viruses holds great promise for mitigating crop losses and improving plant productivity and yields, thereby enhancing food security. Several approaches have been employed to boost immunity in plants by interfering with the transmission or lifecycles of viruses. In this review, we discuss the successful application of clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein (Cas) (CRISPR/Cas) systems to engineer plant immunity, increase plant resistance to viruses, and develop viral diagnostic tools. Furthermore, we examine the use of plant viruses as delivery systems to engineer virus resistance in plants and provide insight into the limitations of current CRISPR/Cas approaches and the potential of newly discovered CRISPR/Cas systems to engineer better immunity and develop better diagnostics tools for plant viruses. Finally, we outline potential solutions to key challenges in the field to enable the practical use of these systems for crop protection and viral diagnostics.

ABSTRACTFlexible filamentous viruses make up a large fraction of the known plant viruses, but in comparison with those of other viruses, very little is known about their structures. We have used fiber diffraction, cryo-electron microscopy, and scanning transmission electron microscopy to determine the symmetry of a potyvirus, soybean mosaic virus; to confirm the symmetry of a potexvirus, potato virus X; and to determine the low-resolution structures of both viruses. We conclude that these viruses and, by implication, most or all flexible filamentous plant viruses share a common coat protein fold and helical symmetry, with slightly less than 9 subunits per helical turn.

Résumé :

AbstractAn increasing number of plant viruses and viroids have been reported from all over the world due largely to metavirogenomics approaches with technological innovation. Herein, the official changes of virus taxonomy, including the establishment of megataxonomy and amendments of the codes of virus classification and nomenclature, recently made by the International Committee on Taxonomy of Viruses were summarized. The continued efforts of the plant virology community of Japan to index all plant viruses and viroids occurring in Japan, which represent 407 viruses, including 303 virus species and 104 unclassified viruses, and 25 viroids, including 20 species and 5 unclassified viroids, as of October 2021, were also introduced. These viruses and viroids are collectively classified into 81 genera within 26 families of 3 kingdoms (Shotokuvirae, Orthornavirae, Pararnavirae) across 2 realms (Monodnaviria and Riboviria). This review also overviewed how Japan’s plant virus/viroid studies have contributed to advance virus/viroid taxonomy.

Résumé :

Abstract The practice of using plant viruses in the control of virus diseases, originally demonstrated in 1933 by Salaman (56), arose from observations made over 50 years ago by McKinney (41), Thung (64), and others who reported plants, preinoculated with mild strains of some viruses, and later inoculated with related severe strains, often failed to show symptoms of the severe strains. The phenomenon has been termed “cross protection” (22, 32, 66). The general observation, failure of the severe strain to cause symptoms, is valid but the principles underlying the phenomenon are not understood. For example, 2 strains may exhibit reciprocal protection, but others may not (23, 24, 39). Moreover, evidence is accumulating in some experimental systems that, even though the severe strain may not induce symptoms, it does replicate in the protected plant (7, 17), so that the failure to express symptoms may not necessarily mean failure of the severe strain to infect and replicate. On the other hand, Dodds (16) provided evidence that cross protection between 2 strains of cucumber mosaic virus appears to operate by preventing infection by the challenge strain.

Résumé :

Abstract Nematodes (nematodes) are worms of Kingdom: Animalia, Phylum: Nematode, the second largest group after insects in terms of number and diversity, and does not have a respiratory and circulatory system but They contain a pseudo body cavity and are found in all humid environments in the world and their parasitic species are not visible to the naked eye. So far, more than 4100 species of plant-parasitic nematodes are known, belonging to about 200 genera to more than 30 families. However, the types that transmit viruses do not constitute more than 1% of the number of parasitic nematodes on plants. The mouth parts of nematodes that transmit viruses, represented by the Stylet, are the body structures important in transmitting viruses, and the shaft is usually elongated. Which enables it to feed deeply inside the root of the plant.
