Genomic sequence of a Bohle iridovirus strain isolated from a diseased boreal toad (Anaxyrus boreas boreas) in a North American aquarium.

Arch Virol 2019 Apr 16. Epub 2019 Apr 16.

Department of Microbiology and Immunology, University of Mississippi Medical Center, 2500 North State Street, Jackson, MS, 39216, USA.

Genomic sequence analysis of zoo ranavirus (ZRV) suggests it is a strain of Bohle iridovirus (BIV), a virus that was first detected in, and thought to be confined to, Australia. Furthermore, marked sequence similarity and genomic co-linearity among ZRV, BIV, and German gecko ranavirus (GGRV) are consistent with the view that all three are strains  of Frog virus 3, the type species of the genus Ranavirus, family Iridoviridae.

Regulation of Hazara virus growth through apoptosis inhibition by viral nucleoprotein.

Arch Virol 2019 Apr 4. Epub 2019 Apr 4.

Department of Microbiology, School of Medicine, Wakayama Medical University, 811-1 Kimiidera, Wakayama, 641-8509, Japan.

Hazara virus (HAZV) is closely related to Crimean-Congo hemorrhagic fever virus (CCHFV), but differs in that it is non-pathogenic to humans. Since HAZV was isolated for the first time in 1954, the biological characteristics of this virus, particularly its behavior within culture cells, have not been well-studied, despite its importance as a surrogate model for CCHFV. Nucleoprotein (N) is the main component of viral nucleocapsid and is the most abundant virion protein, it is believed to play a pivotal role in the viral lifecycle. Read More

Preference of the aphid Myzus persicae (Hemiptera: Aphididae) for tobacco plants at specific stages of potato virus Y infection.

Arch Virol 2019 Apr 3. Epub 2019 Apr 3.

Tobacco Research Institute, Chinese Academy of Agricultural Sciences, Qingdao, 266101, People's Republic of China.

Potato virus Y (PVY) is a common pathogen affecting agricultural production worldwide and is mainly transmitted by Myzus persicae in a non-persistent manner. Insect-borne plant viruses can modify the abundance, performance, and behavior of their vectors by altering host plant features; however, most studies have overlooked the fact that the dynamic progression of virus infection in plants can have variable effects on their vectors. We addressed this point in the present study by dividing the PVY infection process in tobacco into three stages (early state, steady state and late state); delineated by viral copy number. Read More

Analysis of new grapevine Pinot gris virus (GPGV) isolates from Northeast Italy provides clues to track the evolution of a newly emerging clade.

Arch Virol 2019 Apr 2. Epub 2019 Apr 2.

Department of Agricultural, Food, Environmental and Animal Sciences, University of Udine, Via delle Scienze, 206, 33100, Udine, Italy.

Grapevine Pinot gris disease (GPGD) has been associated with a trichovirus, namely grapevine Pinot gris virus (GPGV), although the virus has been reported in both symptomatic and asymptomatic plants. Despite the puzzling aetiology of the disease and potentially important role of GPGV, the number of fully sequenced isolates is still rather limited. With the aim of increasing the knowledge on intraspecific diversity and evolution, nine GPGV isolates were collected from different vineyards in the Friuli Venezia Giulia region (Northeast Italy), cloned, sequenced, and subjected to robust phylogenetic and other analyses.

Department of Applied Biology, Chungnam National University, Daejeon, South Korea.

Two isolates of Youcai mosaic virus (YoMV) were obtained, and their full-length genomic sequences were determined. Full-length infectious cDNA clones of each isolate were generated in which the viral sequence was under the control of dual T7 and 35S promoters for both in vitro transcript production and agro-infiltration. Comparison of the predicted amino acid sequences of the encoded proteins revealed only four differences between the isolates: three in the RNA-dependent RNA polymerase (RdRp) (V383I and M492I in the 125-kDa protein and T1245M in the 182-kDa protein); and one in the overlapping region of the movement protein (MP) and coat protein (CP) genes, affecting only the N-terminal domain of CP (CP M17T).

Molecular characterisation of a putative new polerovirus infecting pumpkin (Cucurbita pepo) in Kenya.

Arch Virol 2019 Mar 21. Epub 2019 Mar 21.

Centre for Tropical Crops and Biocommodities, Queensland University of Technology, Brisbane, 4001, Australia.

Next-generation sequencing of RNA extracted from a pumpkin plant with mosaic symptoms in Kenya identified the presence of a polerovirus sequence closely related to pepo aphid-borne yellows virus (PABYV). The near-complete polerovirus sequence comprised 5,810 nucleotides and contained seven putative open reading frames (ORFs) with a genome organisation typical of poleroviruses. BLASTp analysis of the translated sequences of ORFs 0, 1 and 2 revealed that their amino acid sequences differed by more than 10% from the corresponding protein sequences of other poleroviruses.
