Viroids, the simplest RNA replicons: How they manipulate their hosts for being propagated and how their hosts react for containing the infection [PDF]

, 2015
[EN] The discovery of viroids about 45 years ago heralded a revolution in Biology: small RNAs comprising around 350 nt were found to be able to replicate autonomously and to incite diseases in certain plants without encoding proteins, fundamental ...

Incidence of potato virus diseases and their significance for a seed certification program in Lebanon

Phytopathologia Mediterranea, 2001
Potato fields in the two main production areas of Lebanon, the Bekaa and Akkar plains, were surveyed in two growing seasons for viruses and other pathogens of significance for a potato seed certification program.

First Report of Potato Spindle Tuber Viroid in Costa Rica

Plant Disease, 1999
During 1997 to 1998, symptoms of leaf roll, dwarfism, chlorosis, and occasional leaf necrosis were observed on Solanum tuberosum in several plots in Cartago, the principal potato-production region of Costa Rica. Because of the known association between potato leafroll virus (PLRV) and viroids (1) and previous reports of PLRV in Costa Rica, the ...

Non‐coding RNAs in plant stress responses: molecular insights and agricultural applications

Plant Biotechnology Journal, Volume 23, Issue 8, Page 3195-3233, August 2025.
Summary Non‐coding RNAs (ncRNAs) have emerged as crucial regulators in plant responses to environmental stress, orchestrating complex networks that finetune gene expression under both abiotic and biotic challenges. To elucidate this intricate ncRNA crosstalk, this review comprehensively summarizes recent advances in understanding the mechanisms of key ...

Reassessment of Viroid RNA Cytosine Methylation Status at the Single Nucleotide Level

Viruses, 2019
Composed of a few hundreds of nucleotides, viroids are infectious, circular, non-protein coding RNAs able to usurp plant cellular enzymes and molecular machineries to replicate and move in their hosts. Several secondary and tertiary RNA structural motifs

Processing of Nuclear Viroids In Vivo: An Interplay between RNA Conformations [PDF]

, 2007
Replication of viroids, small non-protein-coding plant pathogenic RNAs, entails reiterative transcription of their incoming single-stranded circular genomes, to which the (+) polarity is arbitrarily assigned, cleavage of the oligomeric strands of one or ...

RNAi tools for controlling viroid diseases [PDF]

, 2022
[EN] Viroids are small (250-400 nucleotides), single-stranded, circular RNAs without protein-coding capacity that infect a large number of ornamental and crop plant species, causing high economic losses worldwide.

RNA‐Binding Proteome‐Wide Analysis Reveals Rice RNA‐Binding Proteins Enriched After Sobemovirus Rice Yellow Mottle Virus Infection

Plant Direct, Volume 9, Issue 5, May 2025.
ABSTRACT RNA‐binding protein interactions with viral RNA are crucial in the context of viral infections, as viral RNAs can recruit and reprogram host RNA‐binding proteins (RBPs) during disease progression. Despite their significance, the repertoire of RBPs involved in most viral infections remains inadequately characterized. In Africa, Sobemovirus Rice

Hop Stunt Viroid Expression and Host Responses in Arabidopsis thaliana

Molecular Plant Pathology, Volume 26, Issue 4, April 2025.
The expression of hop stunt viroid (HSVd) in transgenic Arabidopsis thaliana induces similar host responses to those observed in HSVd‐infected cucumber; thus, A. thaliana can be a valuable model for viroid–host interactions. ABSTRACT Arabidopsis thaliana serves as an appealing model for viroid research, though prior infection trials have largely failed.
