Efficient translation of Eggplant mottled dwarf nucleorhabdovirus N and X genes requires both 5′ and 3′ UTRs

Virology Journal, 2021
Background Circularization of RNA mediated by association of translation factors and RNA elements in 5′ and 3′ UTRs is a common feature for translation control in eukaryotes.

An antiviral defense role of AGO2 in plants.

PLoS ONE, 2011
BackgroundArgonaute (AGO) proteins bind to small-interfering (si)RNAs and micro (mi)RNAs to target RNA silencing against viruses, transgenes and in regulation of mRNAs.

COP1, a negative regulator of photomorphogenesis, positively regulates plant disease resistance via double-stranded RNA binding proteins.

PLoS Pathogens, 2018
The E3 ubiquitin ligase COP1 (Constitutive Photomorphogenesis 1) is a well known component of the light-mediated plant development that acts as a repressor of photomorphogenesis.

Analysis of the Replication Proteins and Satellites of the Turnip Crinkle Virus

The FASEB Journal, 2013
The Turnip Crinkle Virus (TCV) is a single‐stranded, positivesense RNA plant virus that serves as a model organism for related human and animal RNA viruses, such as the West Nile, SARS‐CoV and Hepatitis C viruses. All positive‐sense RNA viruses replicate through asymmetrical replication; understanding the detailed biochemistry of this process should ...

A Modified Cas9 Scaffold Allows Extension of the Virus‐Induced Gene Editing Technology to the Large Potyvirus Genus

Plant Biotechnology Journal, EarlyView.
ABSTRACT Plant viruses are recognized as rapid and effective vectors to deliver CRISPR‐Cas reaction components into plants, a strategy termed virus‐induced gene editing (VIGE). However, VIGE is limited by the host range of the viral vectors. Development of new viral vectors to target a broad range of plant species will potentially enable the delivery ...

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.

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-

Defender or accomplice? Dual roles of plant vesicle trafficking in restricting and enabling geminiviral systemic infection

New Phytologist, Volume 249, Issue 6, Page 2986-3002, March 2026.
Summary The vesicle trafficking system enables multidirectional cargo fluxes between endomembrane compartments. However, vesicle trafficking plays dual roles during pathogen infections. In plants, it mediates autophagic immune responses but can also be hijacked by pathogens to facilitate successful infections.

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)
