Genome Sequence and Phylogenetic Analysis of a Novel Comovirus from Tabasco Pepper (Capsicum Frutescens)
Virus Genes (2019) 55:854–858 https://doi.org/10.1007/s11262-019-01707-6 SHORT REPORT Genome sequence and phylogenetic analysis of a novel comovirus from tabasco pepper (Capsicum frutescens) Ricardo Iván Alcalá‑Briseño1 · Pongtharin Lotrakul2 · Rodrigo A. Valverde3 Received: 12 June 2019 / Accepted: 28 September 2019 / Published online: 11 October 2019 © Springer Science+Business Media, LLC, part of Springer Nature 2019 Abstract A virus isolate from tabasco pepper (Capsicum frutescens) has been reported as a strain of the comovirus Andean potato mottle virus (APMoV). Using the replicative intermediate viral dsRNA, the pepper virus strain was sequenced by Illumina MiSeq. The viral genome was de novo assembled resulting in two RNAs with lengths of 6028 and 3646 nt. Nucleotide sequence analysis indicated that they corresponded to the RNA-1 and RNA-2 of a novel comovirus which we tentatively named pepper mild mosaic virus (PepMMV). Predictions of the open reading frame (ORF) of RNA-1 resulted in a single ORF of 5871 nt with fve cistrons typical of comoviruses, cofactor proteinase, helicase, viral protein genome-linked, 3C-like proteinase (Pro), and RNA-dependent RNA polymerase (RdRP). Similarly, sequence analysis of RNA-2 resulted in a single ORF of 3009 nt with two cistrons typical of comoviruses: movement protein and coat protein (large coat protein and small coat proteins). In pairwise amino acid sequence alignments using the Pro-Pol protein, PepMMV shared the closest identities with broad bean true mosaic virus and cowpea mosaic virus, 56% and 53.9% respectively. In contrast, in alignments of the amino acid sequence of the coat protein (small and large coat proteins) PepMMV shared the closest identities to APMoV and red clover mottle virus, 54% and 40.9% respectively. -
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.

We examine the extent to which these viral RNAs have evolved to be physically compact molecules to facilitate encapsulation. Measurements of equal-length viral, non-viral, coding and non-coding RNAs show viral RNAs to have among the smallest sizes in solution, i.e., the highest gel-electrophoretic mobilities and the smallest hydrodynamic radii. Using graph-theoretical analyses we demonstrate that their sizes correlate with the compactness of branching patterns in predicted secondary structure ensembles. The density of branching is determined by the number and relative positions of 3-helix junctions, and is highly sensitive to the presence of rare higher-order junctions with 4 or more helices. -
Virus Particle Structures
Virus Particle Structures Virus Particle Structures Palmenberg, A.C. and Sgro, J.-Y. COLOR PLATE LEGENDS These color plates depict the relative sizes and comparative virion structures of multiple types of viruses. The renderings are based on data from published atomic coordinates as determined by X-ray crystallography. The international online repository for 3D coordinates is the Protein Databank (www.rcsb.org/pdb/), maintained by the Research Collaboratory for Structural Bioinformatics (RCSB). The VIPER web site (mmtsb.scripps.edu/viper), maintains a parallel collection of PDB coordinates for icosahedral viruses and additionally offers a version of each data file permuted into the same relative 3D orientation (Reddy, V., Natarajan, P., Okerberg, B., Li, K., Damodaran, K., Morton, R., Brooks, C. and Johnson, J. (2001). J. Virol., 75, 11943-11947). VIPER also contains an excellent repository of instructional materials pertaining to icosahedral symmetry and viral structures. All images presented here, except for the filamentous viruses, used the standard VIPER orientation along the icosahedral 2-fold axis. With the exception of Plate 3 as described below, these images were generated from their atomic coordinates using a novel radial depth-cue colorization technique and the program Rasmol (Sayle, R.A., Milner-White, E.J. (1995). RASMOL: biomolecular graphics for all. Trends Biochem Sci., 20, 374-376). First, the Temperature Factor column for every atom in a PDB coordinate file was edited to record a measure of the radial distance from the virion center. The files were rendered using the Rasmol spacefill menu, with specular and shadow options according to the Van de Waals radius of each atom. -

Viral Diseases of Soybeans
SoybeaniGrow BEST MANAGEMENT PRACTICES Chapter 60: Viral Diseases of Soybeans Marie A.C. Langham ([email protected]) Connie L. Strunk ([email protected]) Four soybean viruses infect South Dakota soybeans. Bean Pod Mottle Virus (BPMV) is the most prominent and causes significant yield losses. Soybean Mosaic Virus (SMV) is the second most commonly identified soybean virus in South Dakota. It causes significant losses either in single infection or in dual infection with BPMV. Tobacco Ringspot Virus (TRSV) and Alfalfa Mosaic Virus (AMV) are found less commonly than BPMV or SMV. Managing soybean viruses requires that the living bridge of hosts be broken. Key components for managing viral diseases are provided in Table 60.1. The purpose of this chapter is to discuss the symptoms, vectors, and management of BPMV, SMV, TRSV, and AMV. Table 60.1. Key components to consider in viral management. 1. Viruses are obligate pathogens that cannot be grown in artificial culture and must always pass from living host to living host in what is referred to as a “living or green” bridge. 2. Breaking this “living bridge” is key in soybean virus management. a. Use planting dates to avoid peak populations of insect vectors (bean leaf beetle for BPMV and aphids for SMV). b. Use appropriate rotations. 3. Use disease-free seed, and select tolerant varieties when available. 4. Accurate diagnosis is critical. Contact Connie L. Strunk for information.

Vainio 2 and Carmen Büttner 1 1 Faculty of Life Sciences, Albrecht Daniel Thaer-Institute of Agricultural and Horticultural Sciences, Humboldt-Universität zu Berlin, Ber- lin, Germany; [email protected], [email protected] 2 Natural Resources Institute Finland, Latokartanonkaari 9, 00790, Helsinki, Finland; [email protected] * Correspondence: [email protected] Abstract: Forest health is dependent on the variability of microorganisms interacting with the host tree/holobiont. Symbiotic mi- crobiota and pathogens engage in a permanent interplay, which influences the host. Thanks to the development of NGS technol- ogies, a vast amount of genetic information on the virosphere of temperate forests has been gained the last seven years. To estimate the qualitative/quantitative impact of NGS in forest virology, we have summarized viruses affecting major tree/shrub species and their fungal associates, including fungal plant pathogens, mutualists and saprotrophs. The contribution of NGS methods is ex- tremely significant for forest virology. Reviewed data about viral presence in holobionts, allowed us to address the role of the virome in the holobionts. Genetic variation is a crucial aspect in hologenome, significantly reinforced by horizontal gene transfer among all interacting actors. Through virus-virus interplays synergistic or antagonistic relations may evolve, which may drasti- cally affect the health of the holobiont. Novel insights of these interplays may allow practical applications for forest plant protec- tion based on endophytes and mycovirus biocontrol agents. -

Received: 13 May 2020; Accepted: 15 July 2020; Published: date Abstract: Potyviruses are the largest group of plant infecting RNA viruses that cause significant losses in a wide range of crops across the globe. The majority of viruses in the genus Potyvirus are transmitted by aphids in a non-persistent, non-circulative manner and have been extensively studied vis-à-vis their structure, taxonomy, evolution, diagnosis, transmission and molecular interactions with hosts. This comprehensive review exclusively discusses potyviruses and their transmission by aphid vectors, specifically in the light of several virus, aphid and plant factors, and how their interplay influences potyviral binding in aphids, aphid behavior and fitness, host plant biochemistry, virus epidemics, and transmission bottlenecks. We present the heatmap of the global distribution of potyvirus species, variation in the potyviral coat protein gene, and top aphid vectors of potyviruses. Lastly, we examine how the fundamental understanding of these multi-partite interactions through multi-omics approaches is already contributing to, and can have future implications for, devising effective and sustainable management strategies against aphid- transmitted potyviruses to global agriculture.
