The Polerovirus Silencing Suppressor P0 Targets ARGONAUTE Proteins for Degradation [PDF]

open access: yesCurrent Biology, 2007
Plant and animal viruses encode suppressor proteins of an adaptive immunity mechanism in which viral double-stranded RNA is processed into 21-25 nt short interfering (si)RNAs. The siRNAs guide ARGONAUTE (AGO) proteins so that they target viral RNA. Most viral suppressors bind long dsRNA or siRNAs and thereby prevent production of siRNA or binding of ...

A comprehensive survey on the occurrence of Polerovirus (Solemoviridae) causing yellowing disease on cucurbitaceous crops in Tamil Nadu, India

open access: yesJournal of Horticultural Sciences
A roving survey was conducted in and around Coimbatore, Dindigul, and Tiruchirappalli districts of Tamil Nadu, where commercially field-grown bitter gourd, ridge gourd, pumpkin, sponge gourd, snake gourd, and bottle gourd were observed to exhibit virus ...

Genetic Similarity between Cotton Leafroll Dwarf Virus and Chickpea Stunt Disease Associated Virus in India

open access: yesThe Plant Pathology Journal, 2016
The cotton leafroll dwarf virus (CLRDV) is one of the most devastating pathogens of cotton. This malady, known as cotton blue disease, is widespread in South America where it causes huge crop losses. Recently the disease has been reported from India.

Impact of Mutations in Arabidopsis thaliana Metabolic Pathways on Polerovirus Accumulation, Aphid Performance, and Feeding Behavior

open access: yesViruses, 2020
During the process of virus acquisition by aphids, plants respond to both the virus and the aphids by mobilizing different metabolic pathways. It is conceivable that the plant metabolic responses to both aggressors may be conducive to virus acquisition ...

A conditional silencing suppression system for transient expression. [PDF]

open access: yes, 2018
RNA silencing is a powerful tool deployed by plants against viral infection and abnormal gene expression. Plant viruses have evolved a suite of silencing suppressors for counter-defense, which are also widely used to boost transcript and protein ...

Viruses Infecting Greenhood Orchids (Pterostylidinae) in Eastern Australia

open access: yesViruses, 2022
The Australasian biogeographic realm is a major centre of diversity for orchids, with every subfamily of the Orchidaceae represented and high levels of endemism at the species rank.

Polerovirus N-terminal readthrough domain structures reveal molecular strategies for mitigating virus transmission by aphids

open access: yesNature Communications, 2022
The authors present structures of plant polerovirus NRTD proteins that protrude from the viral capsid and show that the purified NRTD can inhibit insect transmission and act as a bioinsecticide, providing a blueprint for control of related viruses.

An endogenous F-box protein regulates ARGONAUTE1 in Arabidopsis thaliana [PDF]

open access: yes, 2010
ARGONAUTE1 (AGO1) mediates microRNA- and small interfering RNA-directed posttranscriptional gene silencing in Arabidopsis thaliana. Mutant alleles of SQUINT (SQN) slightly reduce AGO1 activity and have weak effects on shoot morphology.

Μοριακός χαρακτηρισμός ιών του γένους Polerovirus

open access: yes, 2021
Οι ιοί του γένους Polerovirus αποτελούν, αδιαμφισβήτητα, σοβαρά παθογόνα οικονομικώς σημαντικών καλλιεργειών, καθώς η μόλυνση από ιούς του γένους προκαλεί σημαντικές απώλειες στην παραγωγή. Ορισμένοι, όπως οι BWYV, CtRLV και PLRV, αποτελούν από τους πρώτους φυτικούς ιούς που χαρακτηρίσθηκαν παγκοσμίως, ενώ τα τελευταία χρόνια ο αριθμός των ειδών του ...

The complete nucleotide sequence of the genome of Barley yellow dwarf virus-RMV reveals it to be a new Polerovirus distantly related to other yellow dwarf viruses

open access: yesFrontiers in Microbiology, 2013
The yellow dwarf viruses (YDVs) of the Luteoviridae family represent the most widespread group of cereal viruses worldwide. They include the Barley yellow dwarf viruses (BYDVs) of genus Luteovirus, the Cereal yellow dwarf viruses (CYDVs) and Wheat yellow
