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.

Viroids: from genotype to phenotype just relying on RNA sequence and structural motifs

Frontiers in Microbiology, 2012
As a consequence of two unique physical properties, small size and circularity, viroid RNAs do not code for proteins and thus depend on RNA sequence/structural motifs for interacting with host proteins that mediate their invasion, replication, spread ...

Deep sequencing of small RNAs in tomato for virus and viroid identification and strain differentiation. [PDF]

PLoS ONE, 2012
Small RNAs (sRNA), including microRNAs (miRNA) and small interfering RNAs (siRNA), are produced abundantly in plants and animals and function in regulating gene expression or in defense against virus or viroid infection.

Modern and historical uses of plant grafting to engineer development, stress tolerance, chimeras, and hybrids

The Plant Journal, Volume 121, Issue 4, February 2025.
SUMMARY For millennia, people have grafted plants to propagate them and to improve their traits. By cutting and joining different species or cultivars together, the best properties of shoot and roots are combined in one plant to increase yields, improve disease resistance, modify plant growth or enhance abiotic stress tolerance.

Ribozyme-mediated high resistance against potato spindle tuber viroid in transgenic potatoes [PDF]

Proceedings of the National Academy of Sciences, 1997
A hammerhead ribozyme [R(-)] targeting the minus strand RNA of potato spindle tuber viroid (PSTVd) and a mutated nonfunctional ribozyme [mR(-)] were designed, cloned, and transcribed. As predicted, both monomer and dimer transcripts of the active R(-) ribozyme gene could cleave the PSTVd minus strand dimer RNA into three fragments of 77 ...

Viroids as Companions of a Professional Career

Viruses, 2019
Since the early 1970s when “virus-like” agents were considered as the cause of two diseases (potato spindle tuber and citrus exocortis), their study and further characterization have been linked to the development and use of molecular biology

Characterisation of a Betasatellite Associated With Tomato Yellow Leaf Curl Guangdong Virus and Discovery of an Unusual Modulation of Virus Infection Associated With C4 Protein

Molecular Plant Pathology, Volume 26, Issue 1, January 2025.
The C4 protein, encoded by tomato yellow leaf curl Guangdong virus (TYLCGdV), does not inhibit PTGS or TGS; the C4 protein modulates TYLCGdV infection by regulating the cytosine methylation level of viral genome at different infection stages. ABSTRACT Tomato yellow leaf curl Guangdong virus (TYLCGdV), a monopartite begomovirus first identified in 2004,

Addressing Various Strategies for Combating the Leaf‐Roll Virus in Potato Plants

International Journal of Mathematics and Mathematical Sciences, Volume 2025, Issue 1, 2025.
In this research, we introduced a mathematical simulation that describes the transmission dynamics of the potato leaf‐roll virus (PLRV) and involves some control measures to eliminate the propagation of the PLRV disease. The proposed model consists of four ordinary differential equations divided into two categories: the host (potato plant) and the ...

Characterization of a Tomato Protein Kinase Gene Induced by Infection by Potato spindle tuber viroid

Molecular Plant-Microbe Interactions, 2000
Viroids—covalently closed, circular RNA molecules in the size range of 250 to 450 nucleotides—are the smallest known infectious agents and cause a number of diseases of crop plants.

Viroid and viroid‐like elements in plants and plant‐associated microbiota: a new layer of biodiversity for plant holobionts

New Phytologist, Volume 244, Issue 4, Page 1216-1222, November 2024.
Summary The functional relevance of plant‐associated microorganisms is theoretically framed within the holobiont concept. The role of viruses in plant holobionts is being recognized both for their direct effects when hosted in plants (cryptic plant viruses) and for their indirect effects when infecting microorganisms associated with plants in ...
