Characterization of a novel psyllid-transmitted waikavirus in carrots [PDF]
Virus Research, 2023 Carrots collected from the Western Negev region in Israel during the winter of 2019 showed disease symptoms of chlorosis, leaf curling, a loss of apical dominance, and multiple lateral roots that were not associated with known pathogens of the carrot ...

Common but Nonpersistent Acquisitions of Plant Viruses by Plant-Associated Fungi [PDF]
Viruses, 2022 Investigating a virus’s host range and cross-infection is important for better understanding the epidemiology and emergence of viruses. Previously, our research group discovered a natural infection of a plant RNA virus, cumber mosaic virus (genus ...

European Journal of Plant Pathology, 2020 A new member of the family Secoviridae was discovered in a symptomatic American blackcurrant plant. In-silico analysis of the genome of the virus, blackcurrant waikavirus A (BCWVA), predicted two open reading frames (ORFs). ORF1 encodes a polyprotein with conserved domains of a leader protein, three capsid proteins, a superfamily 3 viral helicase, a 3C-

Role of a Synonymous Mutation at Codon 178 in P1 That Attenuates Potato Virus Y‐Induced Tobacco Vein Necrosis and Its Application for Expressing Human Interferon [PDF]
Molecular Plant Pathology, Volume 27, Issue 6, June 2026.A synonymous mutation at P1 K178 attenuates PVY virulence and abolishes tobacco vein necrosis. This attenuated vector serves as a high‐efficiency plant bioreactor for the production and purification of recombinant human interferons. ABSTRACT Plant virus‐based vectors are gaining significant attention as bioreactors for recombinant protein production ...

Pest categorisation of non‐EU viruses of Ribes L. [PDF]
EFSA Journal, 2019 Following a request from the EU Commission, the Panel on Plant Health addressed the pest categorisation of the viruses of Ribes L. determined as being either non‐EU or of undetermined standing in a previous EFSA opinion. These infectious agents belong to

RNA2‐encoded VP37 protein of Broad bean wilt virus 1 is a determinant of pathogenicity, host susceptibility, and a suppressor of post‐transcriptional gene silencing [PDF]
Molecular Plant Pathology, Volume 21, Issue 11, Page 1421-1435, November 2020., 2020 In this work, we determined using different approaches the role played by the small putative broad bean wilt virus 1 MP (VP37) on virus pathogenicity, host specificity, and suppression of post‐transcriptional gene silencing. Abstract Broad bean wilt virus 1 (BBWV‐1, genus Fabavirus, family Secoviridae) is a bipartite, single‐stranded positive‐sense RNA

Development of an Indirect ELISA and Dot‐Blot Assay for Serological Detection of Rice Tungro Disease [PDF]
BioMed Research International, Volume 2017, Issue 1, 2017., 2017 Rice tungro disease (RTD) is one of the most destructive diseases of rice in South and Southeast Asia. RTD is routinely detected based on visual observation of the plant. However, it is not always easy to identify the disease in the field as it is often confused with other diseases or physiological disorders.

Identification of a novel waikavirus infecting Pittosporum tobira in China
Archives of VirologyAbstract A new waikavirus, tentatively named pittosporum tobira waikavirus (PtWV), was identified in Pittosporum tobira plants with symptoms of leaf abnormality and ringspot in Yunnan, China. The complete genome sequence was determined using high-throughput sequencing and rapid amplification of cDNA ends.

Annals of Applied Biology, 1996 Summary.A survey of rice fields during the main growing seasons in 81 locations from 21 districts of the Southern Terai region of Nepal indicated that rice tungro was primarily restricted to the Hardinath (Janakpur) and Parwanipur (Bara) regions. The tungro incidence in Hardinath ranged from 17% to 51% and in Parwanipur from 6% to 61% causing about 89%
