Cassava brown streak virus evolves with a nucleotide-substitution rate that is typical for the family Potyviridae [PDF]

Virus Research
The ipomoviruses (family Potyviridae) that cause cassava brown streak disease (cassava brown streak virus [CBSV] and Uganda cassava brown streak virus [UCBSV]) are damaging plant pathogens that affect the sustainability of cassava production in East and ...

The 6-kilodalton peptide 1 of the family Potyviridae: small in size but powerful in function [PDF]

Frontiers in Microbiology
The Potyviridae family is one of the most economically significant groups of plant RNA viruses, causing severe yield losses in agriculturally important crops.

Identification and engineering of highly functional potyviral proteases in cells using co-evolutionary models [PDF]

Nature Communications
Efficiency and substrate specificity of proteases in the Potyviridae family have not been comprehensively profiled. Here we develop a model that learns co-evolutionary features to accurately predict and experimentally validate protease performance at ...

Evaluating the Negative-Strand Coding Potential in Plum Pox Virus. [PDF]

Mol Plant Pathol
Plum 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 ...

Recombinant Potyvirus lilimaculae in asymptomatic Galanthus nivalis: Ecological and evolutionary implications. [PDF]

PLoS ONE
Snowdrops are economically important early-spring flowering geophytes. They are protected both in Hungary and across the European Union, and their international trade is regulated under the Washington Convention.

Targeting dCas9-SunTag to a Susceptibility Gene Promoter Is Sufficient for CRISPR Interference. [PDF]

Plant Direct
ABSTRACT Cassava production in sub‐Saharan Africa is severely impacted by diseases. Most pathogens require interaction with host susceptibility factors to complete their life cycles and cause disease. Targeted DNA methylation is an epigenetic strategy to alter gene expression in plants, and we previously reported that a zinc‐finger fused to DMS3 could ...

Engineering the 3'-UTR of Tobacco Vein Mottling Virus to Confer Cross-Protection Against Potyviruses. [PDF]

Mol Plant Pathol
The 3′‐untranslated region (3′‐UTR) and its secondary structure of virus genomic RNA of tobacco vein mottling virus (TVMV) are important in symptoms attenuation, which can be engineered for cross‐protection against further viral infection. We provide experimental evidence that supports the roles of 3′‐UTR in potyvirus infection.

Diverse, novel mycoviruses coinfecting the phytopathogenic fungus Corynespora cassiicola from Sesamum indicum [PDF]

Frontiers in Cellular and Infection Microbiology
IntroductionCorynespora leaf spot caused by Corynespora cassiicola is one of the most serious foliar diseases of sesame. Mycoviruses can infect various groups of fungi and have certain potential biocontrol value. However, the number of mycovirus reported

Insights Into Virus-Encoded RNA Silencing Suppressors Across Viral Families: A Focus on Viruses Infecting Solanaceae Crops. [PDF]

Physiol Plant
ABSTRACT 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.

Reconceptualizing transcriptional slippage in plant RNA viruses [PDF]

mBio
RNA viruses have evolved sophisticated strategies to exploit the limited encoded information within their typically compact genomes. One of them, named transcriptional slippage (TS), is characterized by the appearance of indels in nascent viral RNAs ...
