Role of RNA silencing in plant-viroid interactions and in viroid pathogenesis [PDF]

, 2023
[EN] Viroids are small, single-stranded, non-protein coding and circular RNAs able to infect host plants in the absence of any helper virus. They may elicit symptoms in their hosts, but the underlying molecular pathways are only partially known.

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.

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 ...

Applying methods of replication and recovery of potato microplants (Solanum tuberosum l.) in seed production [PDF]

E3S Web of Conferences, 2020
Potatoes are strongly affected by pests and by pathogens of fungal, bacterial and viral nature. The most common and economically significant potato viruses are Y (PVY), X (PVX), S (PVS), M (PVM), and potato leaf twisting virus (PLRV).

Small RNA derived from the virulence modulating region of the Potato spindle tuber viroid silences callose synthase genes of tomato plants [PDF]

, 2015
: The tomato (Solanum lycopersicum) callose synthase genes CalS11-like and CalS12-like encode proteins that are essential for the formation of callose, a major component of pollen mother cell walls; these enzymes also function in callose formation during

Chain Risk Model for quantifying cost effectiveness of phytosanitary measures [PDF]

, 2010
A Chain Risk Model (CRM) was developed for a cost effective assessment of phytosanitary measures. The CRM model can be applied to phytosanitary assessments of all agricultural product chains.

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,

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

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 ...

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.
