Viral Infection Risk Driven by Ecological Trait Susceptibility to Habitat Heterogeneity. [PDF]

open access: yesMol Ecol
ABSTRACT Traits for host exploitation that drive the transmission of disease and pathogen emergence are expressed in heterogenous environments. To advance the development of accurate forecasting of infection risk and emergence, determining constraints on ecological strategies for resource use by pathogens over a range of host communities is essential ...

Characterization of a Potyvirus Infecting Sunflower in Argentina [PDF]

open access: yesPlant Disease, 1998
A virus causing chlorotic mottling symptoms on sunflower was found in various locations in Argentina. Symptoms were small chlorotic spots, yellow blotches on leaves, and plant stunting. Virus transmission efficiency by mechanical inoculation was 73 to 100%, and by Myzus persicae was 31 to 49%.

Two diseases of dimorphotheca caused by lettuce mosaic potyvirus and tomato spotted wilt tospovirus

open access: yes, 1999
In 1997, virus-like symptoms were observed in dimorphotheca plants (Dimorphotheca sinuata) at two different locations in Greece. In a greenhouse near Heraklion (Crete), plants showed chlorotic patches mainly in the older leaves, and a mild stunting; near

The Cucumber vein yellowing virus Silencing Suppressor P1b Can Functionally Replace HCPro in Plum pox virus Infection in a Host-Specific Manner

open access: yesMolecular Plant-Microbe Interactions, 2012
Plant viruses of the genera Potyvirus and Ipomovirus (Potyviridae family) use unrelated RNA silencing suppressors (RSS) to counteract antiviral RNA silencing responses.

Arable weeds identified as new sources of beet mosaic potyvirus in Greece

open access: yes, 1997
Field and laboratory studies were carried out between 1992 and 1994 to assess the potential for arable weeds to act as reservoirs of beet mosaic potyvirus (BtMV) in fields where sugar beet is cultivated for seed.

Encapsidation of Potyviral RNA in Various Forms of Transgene Coat Protein Is Not Correlated with Resistance in Transgenic Plants

open access: yesMolecular Plant-Microbe Interactions, 1997
Transgenic plants expressing either bean yellow mosaic potyvirus or chimeric potyvirus coat protein (CP) were inoculated with various potyviruses. Antigen-coated plate, indirect enzyme-linked immunosorbent assay and immunoelectron microscopy of virus ...

Interplay of HCPro and CP in the Regulation of Potato Virus A RNA Expression and Encapsidation

open access: yesViruses, 2022
Potyviral coat protein (CP) and helper component-proteinase (HCPro) play key roles in both the regulation of viral gene expression and the formation of viral particles.

Single and dual RPA‐CRISPR/Cas assays for point‐of‐need detection of Stewart's wilt pathogen (Pantoea stewartii subsp. stewartii) of corn and Maize dwarf mosaic virus

open access: yesPest Management Science, Volume 81, Issue 4, Page 1988-1999, April 2025.
Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge

open access: yesInsect Science, EarlyView.
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...
