“…To this date, research has stated that multiple viruses may infect plants or be carried within insects, but the virus genus that dominates later may change among ecosystems (Gutiérrez et al 2010;Gil-Salas et al 2012). Insects may provide selection on viruses that are transmitted to plants and are able to multiply within their bodies (Webster et al 2018;Tian et al 2019). Meanwhile, competition between viruses may also occur within plants that result in different dominating virus genus in infected plants and will later affect virus genus to be transmitted by insect vectors (Syller 2012).…”

Abstract. Kurnia TD, Purwantoro A, Sulandari S, Basunanda P, Setiawan AB, Fatmawati Y, Andika IP. 2022. Molecular and morpho-physiological identification of yellow leaf curl disease of cucumber in Salatiga, Indonesia. Biodiversitas 23: 1466-1474. Plant viruses are a limiting factor in Indonesian cucumber production. However, because numerous viruses generate identical symptoms on infected plants across cucumber cultivars, identify the virus discovered in the field. The management of virus diseases on plants is dependent on accurately identifying symptoms associated with certain viruses among cucumber cultivars and evaluating possible insect vectors. Because there have been several reports of infected viruses on cucumbers, generating resistant cultivars, identifying phenotypic and physiological disorders, and probable insect vectors are all important aspects of plant disease management. This study aimed to determine the virus and putative insect vectors of yellow leaf curl disease and its symptoms, including morphology and physiology disorders in cucumber cultivars. Common symptoms found included curling, yellow spots, malformed shapes, mortality from severely infested leaves, yellowing, and malformed cucumbers, with occurrences varying among cucumber cultivars. Curling and yellow spots were found on >70% samples of all tested cultivars. Virus infection affected agronomic features and fruit characteristics differently depending on cucumber cultivars. Molecular detection confirmed that polerovirus infected plants and insects tested also carried the Polerovirus. This study provides initial information on monitoring various infection stages of yellow curling disease and potential insect vectors of this disease that will later be useful to synthesize effective management practice in the future.

The Expanding Menagerie of Prunus-Infecting Luteoviruses

Members of the genus Luteovirus are responsible for economically destructive plant diseases worldwide. Over the past few years, three luteoviruses infecting Prunus trees have been characterized. However, the biological properties, prevalence, and genetic diversity of those viruses have not yet been studied. High throughput sequencing of samples of various wild, cultivated, and ornamental Prunus species enabled the identification of four novel species in the genus Luteovirus for which we obtained complete or nearly complete genomes. Besides, we identified another new putative species recovered from Sequence Read Archive data. Furthermore, we conducted a survey on peach-infecting luteoviruses in eight European countries. Analyses of 350 leaf samples collected from germplasm, production orchards, and private gardens showed that peach-associated luteovirus (PaLV), nectarine stem pitting-associated virus (NSPaV), and a novel luteovirus, peach-associated luteovirus 2 (PaLV2), are present in all countries, while the most prevalent virus was NSPaV, followed by PaLV. An analysis of the genetic diversity of these viruses was also conducted. Moreover, the biological indexing on GF305 peach indicator plants demonstrated that PaLV and PaLV2, like NSPaV, are transmitted by graft at relatively low rates. No clear viral symptoms have been observed either in graft-inoculated GF305 indicators, or in different peach tree varieties observed in an orchard. The data generated during this study provide a broader overview of the genetic diversity, geographical distribution and prevalence of peach-infecting luteoviruses, and suggest these viruses are likely asymptomatic in peach under most circumstances.

Population Genomics of Plant Viruses: The Ecology and Evolution of Virus Emergence

2021

View full text Add to dashboard Cite

The genomics era has revolutionized studies of adaptive evolution by monitoring large numbers of loci throughout the genomes of many individuals. Ideally, the investigation of emergence in plant viruses requires examining the population dynamics of both virus and host, their interactions with each other, with other organisms and the abiotic environment. Genetic mechanisms that affect demographic processes are now being studied with high-throughput technologies, traditional genetics methods, and new computational tools for big-data. In this review, we discuss the utility of these approaches to monitor and detect changes in virus populations within cells and individuals, and over wider areas across species and communities of ecosystems. The advent of genomics in virology has fostered a multi-disciplinary approach to tackling disease risk. The ability to make sense of the information now generated in this integrated setting is by far the most substantial obstacle to the ultimate goal of plant virology to minimize the threats to food security posed by disease. To achieve this goal, it is imperative to understand and forecast how populations respond to future changes in complex natural systems.
