Insights Into Virus-Encoded RNA Silencing Suppressors Across Viral Families: A Focus on Viruses Infecting Solanaceae Crops. [PDF]
Physiol PlantABSTRACT Viral suppressors of RNA silencing (VSRs) are proteins that interfere with antiviral defense mechanisms and enhance infection. For plant viruses, VSRs can be encoded in viral genomes and satellite molecules and play an important role in the virus's life cycle and in overcoming host defenses.

The Molecular Cochaperone NbSGT1 May Function as an Endogenous Suppressor of RNA Silencing That Is Recruited by a Potyvirus in Infection of Plants. [PDF]
Mol Plant PatholThe molecular co‐chaperone NbSGT1 interacts with potyviral HC‐Pro and promotes viral infection in plants. Notably, (1) NbSGT1 enhances the RSS activity of HC‐Pro and (2) NbSGT1 acts as an endogenous suppressor of RNA silencing (ESR), suppressing RNA silencing in plants.

Effect of disease prevalence and growth stage on symptom severity in the Turnip mosaic virus – Arabidopsis thaliana pathosystem [PDF]
Journal of Plant Protection Research, 2023 In response to stresses, plants are capable of communicating their physiological status to other individuals in the community using several chemical cues. Nearby receivers then adjust their own homeostasis to increase resilience.

Host Range Evolution of Potyviruses: A Global Phylogenetic Analysis
Viruses, 2020 Virus host range, i.e., the number and diversity of host species of viruses, is an important determinant of disease emergence and of the efficiency of disease control strategies. However, for plant viruses, little is known about the genetic or ecological

Evaluating the Negative-Strand Coding Potential in Plum Pox Virus. [PDF]
Mol Plant PatholPlum pox virus produces two polyproteins from ORFs in the positive strand. This study explores the possible expression of peptides from negative‐strand ORFs (rORFs). ABSTRACT Recent studies proposed that the negative strands of some single‐stranded, positive‐sense RNA viruses contain reverse open reading frames (rORFs) that encode functional peptides ...
