A self-perpetuating repressive state of a viral replication protein blocks superinfection by the same virus.

PLoS Pathogens, 2017
Diverse animal and plant viruses block the re-infection of host cells by the same or highly similar viruses through superinfection exclusion (SIE), a widely observed, yet poorly understood phenomenon. Here we demonstrate that SIE of turnip crinkle virus (

Cap-Independent Translational Enhancement of Turnip Crinkle Virus Genomic and Subgenomic RNAs [PDF]

Journal of Virology, 2000
ABSTRACT The presence of translational control elements and cap structures has not been carefully investigated for members of the Carmovirus genus, a group of small icosahedral plant viruses with positive-sense RNA genomes.

Systemic infection of tobacco mosaic virus is limited by upward transport and phloem unloading without coat protein

The Plant Journal, Volume 127, Issue 3, August 2026.
SUMMARY Coat protein (CP) is widely viewed as essential for systemic infection of tobacco mosaic virus (TMV), yet the mechanistic basis of this requirement remains incompletely resolved. In this study, we show that TMV can still achieve long‐distance vascular transport in the absence of CP, but systemic infection becomes intermittent because the ...

Silencing Suppressor Protein p26 of Areca Palm Velarivirus 1 (APV1) Interacts With SGS3 and Promotes Its Degradation Via the Ubiquitination Pathway

Molecular Plant Pathology, Volume 27, Issue 7, July 2026.
APV1‐encoded p26 protein is a multifunctional VSR that suppresses RNA silencing and blocks the systemic spread of silencing signals. p26 interacts with host SGS3, a key component of the plant antiviral silencing pathway, and targets SGS3 for accelerated degradation via the ubiquitination pathway.

Superinfection Exclusion by p28 of Turnip Crinkle Virus Is Separable from Its Replication Function [PDF]

Molecular Plant-Microbe Interactions®, 2020
We recently reported that the p28 auxiliary replication protein encoded by turnip crinkle virus (TCV) is also responsible for eliciting superinfection exclusion (SIE) against superinfecting TCV. However, it remains unresolved whether the replication function of p28 could be separated from its ability to elicit SIE.

Enhanced Rice Yellow Mottle Virus Resistance via CRISPR/Cas9‐Targeted Mutagenesis of the Rice eIF(iso)4G Gene

Molecular Plant Pathology, Volume 27, Issue 7, July 2026.
Using CRISPR/Cas9 to edit the susceptibility gene in rice eIF(iso)4G helped to lower the infection of rice yellow mottle virus in mutated lines of the Indica rice cultivar IR2793‐80‐01. ABSTRACT Rice is a staple crop primarily recognised for its high content of carbohydrates and proteins.

Preparation of Biologically Active Arabidopsis Ribosomes and Comparison with Yeast Ribosomes for Binding to a tRNA-Mimic that Enhances Translation of Plant Plus-Strand RNA Viruses

Frontiers in Plant Science, 2013
Isolation of biologically active cell components from multicellular eukaryotic organisms often poses difficult challenges such as low yields and inability to retain the integrity and functionality of the purified compound. We previously identified a cap-

The Transcription Factor DPB Confers Antiviral Defence Against Potato Virus X by Modulating MYB‐Dependent Signalling

Molecular Plant Pathology, Volume 27, Issue 7, July 2026.
This study identified that NbDPB confers resistance to potato virus X by directly activating the transcription factor NbMYB, which engages a hormone‐signalling network likely involving jasmonic acid and salicylic acid pathways. ABSTRACT As a transcriptional co‐factor of E2F, DP proteins are typically involved in the regulation of plant cell‐cycle ...

A Versatile Assay for the Identification of RNA Silencing Suppressors Based on Complementation of Viral Movement

Molecular Plant-Microbe Interactions, 2008
The cell-to-cell movement of Turnip crinkle virus (TCV) in Nicotiana benthamiana requires the presence of its coat protein (CP), a known suppressor of RNA silencing. RNA transcripts of a TCV construct containing a reporter gene (green fluorescent protein)

In Vivo Removal of N-Terminal Fusion Domains From Recombinant Target Proteins Produced in Nicotiana benthamiana

Frontiers in Plant Science, 2020
Plants show great potential for producing recombinant proteins in a cost-effective manner. Many strategies have therefore been employed to express high levels of recombinant proteins in plants.
