Viral non-coding RNAs are gaining much value and interest for the potential impact played in host gene regulation, acting as fine tuners of host cellular defense mechanisms. The implicit importance of v-ncRNAs resides first in the limited genomes size of viruses carrying only strictly necessary genomic sequences. The other crucial and appealing characteristic of v-ncRNAs is the non-immunogenicity, making them the perfect expedient to be used in the never-ending virus-host war. In this review, we wish to examine how DNA and RNA viruses have evolved a common strategy and which the crucial host pathways are targeted through v-ncRNAs in order to grant and facilitate their life cycle.

  • Symptom Recovery in Tomato Ringspot Virus Infected Nicotiana
    SYMPTOM RECOVERY IN TOMATO RINGSPOT VIRUS INFECTED NICOTIANA BENTHAMIANA PLANTS: INVESTIGATION INTO THE ROLE OF PLANT RNA SILENCING MECHANISMS by BASUDEV GHOSHAL B.Sc., Surendranath College, University of Calcutta, Kolkata, India, 2003 M. Sc., University of Calcutta, Kolkata, India, 2005 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in THE FACULTY OF GRADUATE AND POSTDOCTORAL STUDIES (Botany) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) August 2014 © Basudev Ghoshal, 2014 Abstract Symptom recovery in virus-infected plants is characterized by the emergence of asymptomatic leaves after a systemic symptomatic phase of infection and has been linked with the clearance of the viral RNA due to the induction of RNA silencing. However, the recovery of Tomato ringspot virus (ToRSV)-infected Nicotiana benthamiana plants is not associated with viral RNA clearance in spite of active RNA silencing triggered against viral sequences. ToRSV isolate Rasp1-infected plants recover from infection at 27°C but not at 21°C, indicating a temperature-dependent recovery. In contrast, plants infected with ToRSV isolate GYV recover from infection at both temperatures. In this thesis, I studied the molecular mechanisms leading to symptom recovery in ToRSV-infected plants. I provide evidence that recovery of Rasp1-infected N. benthamiana plants at 27°C is associated with a reduction of the steady-state levels of RNA2-encoded coat protein (CP) but not of RNA2. In vivo labelling experiments revealed efficient synthesis of CP early in infection, but reduced RNA2 translation later in infection. Silencing of Argonaute1-like (NbAgo1) genes prevented both symptom recovery and RNA2 translation repression at 27°C.

  • Tomato Ringspot Virus
    -- CALIFORNIA D EP ARTM ENT OF cdfaFOOD & AGRICULTURE ~ California Pest Rating Proposal for Tomato ringspot virus Current Pest Rating: C Proposed Pest Rating: C Realm: Riboviria; Phylum: incertae sedis Family: Secoviridae; Subfamily: Comovirinae Genus: Nepovirus Comment Period: 6/2/2020 through 7/17/2020 Initiating Event: On August 9, 2019, USDA-APHIS published a list of “Native and Naturalized Plant Pests Permitted by Regulation”. Interstate movement of these plant pests is no longer federally regulated within the 48 contiguous United States. There are 49 plant pathogens (bacteria, fungi, viruses, and nematodes) on this list. California may choose to continue to regulate movement of some or all these pathogens into and within the state. In order to assess the needs and potential requirements to issue a state permit, a formal risk analysis for Tomato ringspot virus (ToRSV) is given herein and a permanent pest rating is proposed. History & Status: Background: Tomato ringspot virus is widespread in North America. Despite the name, it is of minor importance to tomatoes. However, it infects many other hosts and causes particularly severe losses on perennial woody plants including fruit trees and brambles. ToRSV is a nepovirus; “nepo” stands for nematode- transmitted polyhedral. It is part of a large group of more than 30 viruses, each of which may attack many annual and perennial plants and trees. They cause severe diseases of trees and vines. ToRSV is vectored by dagger nematodes in the genus Xiphinema and sometimes spreads through seeds or can be transmitted by pollen to the pollinated plant and seeds. ToRSV is often among the most important diseases for each of its fruit tree, vine, or bramble hosts, which can suffer severe losses in yield or be -- CALIFORNIA D EP ARTM ENT OF cdfaFOOD & AGRICULTURE ~ killed by the virus.

Wilsona,# aDepartment of Microbiology, New York University School of Medicine, New York, New York, USA bDepartment of Medicine, New York University School of Medicine, New York, New York, USA cBeneVir Biopharm, Inc., Gaithersburg, Maryland, USA Abstract Herpes simplex virus 1 (HSV-1) is a widespread pathogen that persists for life, replicating in surface tissues and establishing latency in peripheral ganglia. Increasingly, molecular studies of latency use cultured neuron models developed using recombinant viruses such as HSV-1 GFP- US11, a derivative of strain Patton expressing green fluorescent protein (GFP) fused to the viral US11 protein. Visible fluorescence follows viral DNA replication, providing a real time indicator of productive infection and reactivation. Patton was isolated in Houston, Texas, prior to 1973, and distributed to many laboratories. Although used extensively, the genomic structure and phylogenetic relationship to other strains is poorly known. We report that wild type Patton and the GFP-US11 recombinant contain the full complement of HSV-1 genes and differ within the unique regions at only eight nucleotides, changing only two amino acids. Although isolated in North America, Patton is most closely related to Asian viruses, including KOS63.

Typically, HCMV causes asymptomatic infection in the immunocompetent population, while in immunocompromised individuals or when transmitted vertically from the mother to the fetus it leads to systemic disease with severe complications and high mortality rate. Following primary infection, HCMV establishes a state of latency primarily in myeloid cells, from which it can be reactivated by various inflammatory stimuli. Several studies have shown that HCMV, despite being a DNA virus, is highly prone to genetic variability that strongly influences its replication and dissemination rates as well as cellular tropism. In this scenario, the few currently available drugs for the treatment of HCMV infections are characterized by high toxicity, poor oral bioavailability, and emerging resistance.

Approximately 20% of human cancers is attributable to DNA oncogenic viruses such as human papillomavirus (HPV), hepatitis B virus (HBV), and Epstein-Barr virus (EBV). Unrepaired DNA damage is the most common and overlapping feature of these DNA oncogenic viruses and a source of genomic instability and tumour development. Sustained DNA damage results from unceasing production of reactive oxygen species and activation of inflammasome cascades that trigger genomic changes and increased propensity of epigenetic alterations. Accumulation of epigenetic alterations may interfere with genome-wide cellular signalling machineries and promote malignant transformation leading to cancer development.

Four new RNA viruses were discovered in the FYD-affected plant by the virome analysis using high-throughput sequencing of transcriptome and small RNAs. The complete genomes were determined, and based on the sequence and phylogenetic analysis, they are considered to be new members of the genera Nepovirus (Secoviridae), Idaeovirus (unassigned), Enamovirus (Luteoviridae), and Nucleorhabdovirus (Rhabdoviridae), respectively. Therefore, the tentative names corresponding to these viruses are green Sichuan pepper-nepovirus (GSPNeV), -idaeovirus (GSPIV), -enamovirus (GSPEV), and -nucleorhabdovirus (GSPNuV). The viral population analysis showed that GSPNeV and GSPIV were dominant in the virome. The small RNA profiles of these viruses are in accordance with the typical virus-plant interaction model for Arabidopsis thaliana.

Previously, only limited reports have shown the genetic variation of BBWV2. Meanwhile, the detailed evolution- ary changes, synonymous codon usage bias and host adaptation of this virus are largely unclear. Here, we performed comprehensive analyses of the phylodynamics, reassortment, composition bias and codon usage pattern of BBWV2 using forty-two complete genome sequences of BBWV-2 isolates together with two other full-length RNA1 sequences and six full-length RNA2 sequences. Both recombination and reassortment had a significant influence on the genomic evolution of BBWV2. Through phylogenetic analysis we detected three and four lineages based on the ORF1 and ORF2 nonrecombinant sequences, respectively. The evolutionary rates of the two BBWV2 ORF coding sequences were 8.895 × 10−4 and 4.560 × 10−4 subs/site/year, respectively. We found a relatively conserved and stable genomic composition with a lower codon usage choice in the two BBWV2 protein coding sequences.

Abstract: Most plant viruses code for movement proteins (MPs) targeting plasmodesmata to enable cell-to-cell and systemic spread in infected plants. Small membrane-embedded MPs have been first identified in two viral transport gene modules, triple gene block (TGB) coding for an RNA-binding helicase TGB1 and two small hydrophobic proteins TGB2 and TGB3 and double gene block (DGB) encoding two small polypeptides representing an RNA-binding protein and a membrane protein. These findings indicated that movement gene modules composed of two or more cistrons may encode the nucleic acid-binding protein and at least one membrane-bound movement protein. The same rule was revealed for small DNA-containing plant viruses, namely, viruses belonging to genus Mastrevirus (family Geminiviridae) and the family Nanoviridae. In multi-component transport modules the nucleic acid-binding MP can be viral capsid protein(s), as in RNA-containing viruses of the families Closteroviridae and Potyviridae. However, membrane proteins are always found among MPs of these multicomponent viral transport systems.
