Genetic variability of potato spindle tuber viroid RNA replicon.

Acta Biochimica Polonica, 2001
The genetic continuity of the potato spindle tuber viroid (PSTVd) genome was analysed after infection of tomato plants with cloned cDNAs of parental strains. During the six weeks of the experiment, several new sequence variants appeared. The sequence variants detected in the progeny population induced sequence-specific disease symptoms.

First report of potato spindle tuber viroid isolated from pepper seeds produced in Vietnam

Journal of General Plant Pathology
Potato spindle tuber viroid (PSTVd; genus Pospiviroid) was detected from pepper (Capsicum annuum) seeds produced in Vietnam during an export inspection. The PSTVd isolate (PSTVd-VN) maintained its viability. The phylogenetic relationship between PSTVd-VN

miR398‐Dirigent Module Negatively Regulates Cassava Resistance to Cassava Common Mosaic Virus by Affecting the Cell Wall Lignification and Thickness

Molecular Plant Pathology, Volume 26, Issue 10, October 2025.
miR398‐Dirigent module reduces cell wall lignification in cassava, weakening resistance to cassava common mosaic virus. Overexpressing Dir increases cell wall lignification and enhances resistance. ABSTRACT Studies have demonstrated microRNA398 (miR398) hyperaccumulation in plant species infected with viruses; however, its role in a viral context ...

Cellular Basis of Potato Spindle Tuber Viroid Systemic Movement

Virology, 2001
Viroids are small, nontranslatable pathogenic RNAs that replicate autonomously and traffic systemically in their host plants. We have used in situ hybridization to analyze the trafficking pattern of Potato spindle tuber viroid (PSTVd) in tomato and Nicotiana benthamiana.

RepA Protein of Citrus Chlorotic Dwarf‐Associated Virus Impairs Perinuclear Chloroplast Clustering Induced by Lemon Chloroplast Malate Dehydrogenase

Molecular Plant Pathology, Volume 26, Issue 8, August 2025.
RepA encoded by citrus chlorotic dwarf‐associated virus inhibits Citrus limon chloroplast malate dehydrogenase (ClMDH) induced perinuclear chloroplast clustering and hijacks ClMDH to the nucleus. ABSTRACT Replication‐related protein A (RepA), encoded by the citrus chlorotic dwarf‐associated virus (CCDaV), induces hypersensitive response (HR)‐like cell ...

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 ...

Transformation of Seed Non-Transmissible Hop Viroids in Nicotiana benthamiana Causes Distortions in Male Gametophyte Development

Plants, 2021
Viroids are small, non-coding, parasitic RNAs that promote developmental distortions in sensitive plants. We analyzed pollen of Nicotiana benthamiana after infection and/or ectopic transformation with cDNAs of citrus bark cracking viroid (CBCVd), apple ...

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

Viroids and Viroid Disease Agents Detected in Turkey

Türkiye Tarımsal Araştırmalar Dergisi, 2015
Viroids are circular, single-stranded RNAs that infect plants. Viroids belong to two families, Pospiviroidae and Avsunviroidae, whose members replicate in the nucleus and chloroplast of plant cells, respectively.

Different rates of spontaneous mutation of chloroplastic and nuclear viroids as determined by high-fidelity ultra-deep sequencing.

PLoS Pathogens, 2017
Mutation rates vary by orders of magnitude across biological systems, being higher for simpler genomes. The simplest known genomes correspond to viroids, subviral plant replicons constituted by circular non-coding RNAs of few hundred bases. Previous work
