The Evolution, Diversity, and Host Associations of Rhabdoviruses Ben Longdon,1,* Gemma G
Virus Evolution, 2015, 1(1): vev014 doi: 10.1093/ve/vev014 Research article The evolution, diversity, and host associations of rhabdoviruses Ben Longdon,1,* Gemma G. R. Murray,1 William J.

These new viruses are poorly characterized and new approaches are needed predict the host species these viruses pose a risk to. The rhabdoviruses are a diverse family of RNA viruses that includes important pathogens of humans, animals, and plants. We have discovered thirty-two new rhabdoviruses through a combination of our own RNA sequencing of insects and searching public sequence databases. Combining these with previously known sequences we reconstructed the phylogeny of 195 rhabdovirus by guest on December 14, 2015 sequences, and produced the most in depth analysis of the family to date. In most cases we know nothing about the biology of the viruses beyond the host they were identified from, but our dataset provides a powerful phylogenetic approach to predict which are vector-borne viruses and which are specific to vertebrates or arthropods. -

The first approach to detect the presence of viruses was based on the occurrence of dsRNA, typically considered as a viral molecule in plants and fungi. Two dsRNA-banding patterns (∼7 and 9 kb) were observed in seven of 73 Halophytophthora isolates tested (9.6%). Consequently, two dsRNA-hosting isolates were chosen to perform stranded RNA sequencing for de novo virus sequence assembly.

Characterization of Farmington Virus, a Novel Virus from Birds That Is Distantly Related to Members of the Family Rhabdoviridae
Palacios et al. Virology Journal 2013, 10:219 http://www.virologyj.com/content/10/1/219 RESEARCH Open Access Characterization of Farmington virus, a novel virus from birds that is distantly related to members of the family Rhabdoviridae Gustavo Palacios1†, Naomi L Forrester2,3,4†, Nazir Savji5,7†, Amelia P A Travassos da Rosa2, Hilda Guzman2, Kelly DeToy5, Vsevolod L Popov2,4, Peter J Walker6, W Ian Lipkin5, Nikos Vasilakis2,3,4 and Robert B Tesh2,4* Abstract Background: Farmington virus (FARV) is a rhabdovirus that was isolated from a wild bird during an outbreak of epizootic eastern equine encephalitis on a pheasant farm in Connecticut, USA. Findings: Analysis of the nearly complete genome sequence of the prototype CT AN 114 strain indicates that it encodes the five canonical rhabdovirus structural proteins (N, P, M, G and L) with alternative ORFs (> 180 nt) in the N and G genes. Phenotypic and genetic characterization of FARV has confirmed that it is a novel rhabdovirus and probably represents a new species within the family Rhabdoviridae. Conclusions: In sum, our analysis indicates that FARV represents a new species within the family Rhabdoviridae.

Differential Features of Fusion Activation Within the Paramyxoviridae
viruses Review Differential Features of Fusion Activation within the Paramyxoviridae Kristopher D. Azarm and Benhur Lee * Icahn School of Medicine at Mount Sinai, New York, NY 10029, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-212-241-2552 Received: 17 December 2019; Accepted: 29 January 2020; Published: 30 January 2020 Abstract: Paramyxovirus (PMV) entry requires the coordinated action of two envelope glycoproteins, the receptor binding protein (RBP) and fusion protein (F). The sequence of events that occurs during the PMV entry process is tightly regulated. This regulation ensures entry will only initiate when the virion is in the vicinity of a target cell membrane. Here, we review recent structural and mechanistic studies to delineate the entry features that are shared and distinct amongst the Paramyxoviridae. In general, we observe overarching distinctions between the protein-using RBPs and the sialic acid- (SA-) using RBPs, including how their stalk domains differentially trigger F. Moreover, through sequence comparisons, we identify greater structural and functional conservation amongst the PMV fusion proteins, as compared to the RBPs. When examining the relative contributions to sequence conservation of the globular head versus stalk domains of the RBP, we observe that, for the protein-using PMVs, the stalk domains exhibit higher conservation and find the opposite trend is true for SA-using PMVs. A better understanding of conserved and distinct features that govern the entry of protein-using versus SA-using PMVs will inform the rational design of broader spectrum therapeutics that impede this process.

Tically Expands Our Understanding on Virosphere in Temperate Forest Ecosystems

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. -
The Nucleotide Sequence of RNA1 of Lettuce Big-Vein Virus, Genus Varicosavirus, Reveals Its Relation to Nonsegmented Negative-Strand RNA Viruses
Virology 297, 289–297 (2002) doi:10.1006/viro.2002.1420 The Nucleotide Sequence of RNA1 of Lettuce big-vein virus, Genus Varicosavirus, Reveals Its Relation to Nonsegmented Negative-Strand RNA Viruses Takahide Sasaya,*,1 Koichi Ishikawa,* and Hiroki Koganezawa† *National Agricultural Research Center for Western Region, Zentsuji Campus, Zentsuji, Kagawa 765-8508, Japan; and †National Agricultural Research Center for Western Region, Fukuyama, Hiroshima 721-8514, Japan Received December 12, 2001; accepted February 14, 2002 The complete nucleotide sequence of RNA1 from Lettuce big-vein virus (LBVV), the type member of the genus Varicosa- virus, was determined. LBVV RNA1 consists of 6797 nucleotides and contains one large ORF that encodes a large (L) protein of 2040 amino acids with a predicted Mr of 232,092. Northern blot hybridization analysis indicated that the LBVV RNA1 is a negative-sense RNA. Database searches showed that the amino acid sequence of Lprotein is homologous to those of L polymerases of nonsegmented negative-strand RNA viruses. A cluster dendrogram derived from alignments of the LBVV L protein and the Lpolymerases indicated that the Lprotein is most closely related to the Lpolymerases of plant rhabdoviruses. Transcription termination/polyadenylation signal-like poly(U) tracts that resemble those in rhabdovirus and paramyxovirus RNAs were present upstream and downstream of the coding region. Although LBVV is related to rhabdovi- ruses, a key distinguishing feature is that the genome of LBVV is segmented. The results reemphasize the need to reconsider the taxonomic position of varicosaviruses. © 2002 Elsevier Science (USA) Key Words: Lettuce big-vein virus; Varicosavirus; rhabdovirus; RNA polymerase; nonsegmented negative-strand RNA virus. -

In recent years the collection of paramyxoviruses sequences detected in wild mammals has substantially grown, however little is known about paramyxovirus diversity in North American mammals. To better understand natural paramyxovirus diversity, host range, and host specificity, we sought to comprehensively characterize paramyxoviruses across a range of diverse co-occurring wild small mammals in Southern Arizona. We used highly degenerate primers to screen fecal and urine samples and obtained a total of 55 paramyxovirus sequences from 12 rodent species and 6 bat species. We also performed illumina RNA-seq and de novo assembly on 14 of the positive samples to recover a total of 5 near full-length viral genomes.
