Commodity risk assessment of <i>Petunia</i> spp. and <i>Calibrachoa</i> spp. unrooted cuttings from Uganda. [PDF]

EFSA J
Abstract The European Commission requested the EFSA Panel on Plant Health to evaluate the likelihood of pest freedom at entry in the EU, including both regulated and non‐regulated pests, potentially associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Uganda.

Natural Infection of Pomegranate (Punica Granatum) by Apple Dimple Fruit Viroid

Cells, 2022
The analysis by high throughput sequencing (HTS) and RT-PCR of Spanish pomegranate fruits showing yellow rings revealed the presence of viroid isolates closely related to fig isolates of apple dimple fruit viroid (ADFVd).

Evolutionarily New Solanaceous DCL2 Family Members Acquire Functions in Tomato. [PDF]

Mol Plant Pathol
This work demonstrated the expansion of functional Dicer‐like 2 gene family members in the Solanaceae family. ABSTRACT RNA silencing is one of the major defence activities against viral pathogens in plants. Silencing signals are initiated by Dicer‐like proteins (DCLs) to generate viral‐derived small RNAs (sRNAs).

Emerging value of the viroid model in molecular biology and beyond

Virus Research, 2022
Viroids are single-stranded circular noncoding RNAs that infect plants. Research in the past five decades has deciphered the viroid genome structures, viroid replication cycles, numerous host factors for viroid infection, viroid motifs for intracellular ...

Polyclonal antibodies against potato spindle tuber viroid RNA

Frontiers in Bioscience-Elite, 2022
Ribonucleic acid (RNA) can act as a hapten in the direct immunization of animals. For antigen synthesis, 65 mg of viroid RNA were obtained by in vitro transcription of the recombinant DNA. We received a reasonable immune response in mice and rabbits with

Somatic Embryogenesis: A Tool for Fast and Reliable Virus and Viroid Elimination for Grapevine and other Plant Species

Horticulturae, 2022
Somatic embryogenesis (SE) is a widely used technique in plant biotechnology, and it can be a possible tool for virus and viroid elimination. This review highlights the advantages and limitations of production of pathogen-free plants using somatic ...

Viroids: Non-Coding Circular RNAs Able to Autonomously Replicate and Infect Higher Plants

Biology, 2023
Viroids are a unique type of infectious agent, exclusively composed of a relatively small (246–430 nt), highly base-paired, circular, non-coding RNA.

Precisely Monomeric Linear RNAs of Viroids Belonging to Pospiviroid and Hostuviroid Genera Are Infectious Regardless of Transcription Initiation Site and 5′-Terminal Structure

Cells, 2021
Infectious dimeric RNA transcripts are a powerful tool for reverse genetic analyses in viroid studies. However, the construction of dimeric cDNA clones is laborious and time consuming, especially in mutational analyses by in vitro mutagenesis.
