Grapevine Virus Diseases: Economic Impact and Current Advances in Viral Prospection and Management1
1/22 ISSN 0100-2945 http://dx.doi.org/10.1590/0100-29452017411 GRAPEVINE VIRUS DISEASES: ECONOMIC IMPACT AND CURRENT ADVANCES IN VIRAL PROSPECTION AND MANAGEMENT1 MARCOS FERNANDO BASSO2, THOR VINÍCIUS MArtins FAJARDO3, PASQUALE SALDARELLI4 ABSTRACT-Grapevine (Vitis spp.) is a major vegetative propagated fruit crop with high socioeconomic importance worldwide. It is susceptible to several graft-transmitted agents that cause several diseases and substantial crop losses, reducing fruit quality and plant vigor, and shorten the longevity of vines. The vegetative propagation and frequent exchanges of propagative material among countries contribute to spread these pathogens, favoring the emergence of complex diseases. Its perennial life cycle further accelerates the mixing and introduction of several viral agents into a single plant. Currently, approximately 65 viruses belonging to different families have been reported infecting grapevines, but not all cause economically relevant diseases. The grapevine leafroll, rugose wood complex, leaf degeneration and fleck diseases are the four main disorders having worldwide economic importance. In addition, new viral species and strains have been identified and associated with economically important constraints to grape production. In Brazilian vineyards, eighteen viruses, three viroids and two virus-like diseases had already their occurrence reported and were molecularly characterized. Here, we review the current knowledge of these viruses, report advances in their diagnosis and prospection of new species, and give indications about the management of the associated grapevine diseases. Index terms: Vegetative propagation, plant viruses, crop losses, berry quality, next-generation sequencing.

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. -

Some of these pathogens cause severe crop losses and often reduce the productive life of the orchards. Detection and characterization of these agents in fruit trees is challenging, however, during the last years, the wide application of high-throughput sequencing (HTS) technologies has significantly facilitated this task. In this review, we present recent advances in the discovery, detection, and characterization of fruit tree viruses and virus-like agents accomplished by HTS approaches. -

These authors contributed equally to this work. y Received: 17 June 2019; Accepted: 28 July 2019; Published: 31 July 2019 Abstract: An emerging virus-like flower yellowing disease (FYD) of green Sichuan pepper (Zanthoxylum armatum v. novemfolius) has been recently reported. 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. -

Current Status of Genetically Modified Ornamentals
Current Status of Genetically Modified Ornamentals John Hammond USDA-ARS. United States National Arboretuni Floral and Nursery Plants Research Unit Beltsville MD 20705 USA Keywords: Virus resistance, disease resistance. trarisgenic plants, flower color Abstract Biotechnology offers new means of improving ornamental crops by the addition of desirable traits to existing horticulturally-adapted cultivars. Traditional plant breeding involves the exchange of many hundreds or thousands of genes between related species to create novel combinations, and improved genotypes must be selected from thousands of segregating progeny over multiple c ycles of selection. Introgression of a single desirable new character, such as disease resistance, from an unadapted relative of a crop species may require multiple backcross generations to regain the horticultural or ornamental qualities of the original cultivar, often resulting in reduced intensity of expression of the back-crossed character. In the case of many ornamental species, related germplasm with the desired disease resistance has not been identified. This is particularly true in the case of viruses, where few sources of resistance are known among ornamentals and related species. However, it has been demonstrated that effective resistance against many plant viruses can be obtained, in model systems and in some field crops, by introduction of virus-derived sequences or various anti-viral genes. Viral infection is a significant problem in many ornamentals, and especially floral crops, because so many ornamentals are vegetatively propagated. Virus infection frequently reduces floral quality and value as well as y ield. Transformation of crop species with one or more gene constructs can lead to addition of desirable traits, typically with minimal effects on other desirable characteristics. -
