Cellular Microbiology, 2008 Viroids are small, circular RNA pathogens, which infect several crop plants and can cause diseases of economic importance. They do not code for proteins but they contain a number of RNA structural elements, which interact with factors of the host. The resulting set of sophisticated and specific interactions enables them to use the host machinery for ...

Hybrids of RNA viruses and viroid-like elements replicate in fungi
Nature Communications, 2023 Earth’s life may have originated as self-replicating RNA, and it has been argued that RNA viruses and viroid-like elements are remnants of such pre-cellular RNA world. RNA viruses are defined by linear RNA genomes encoding an RNA-dependent RNA polymerase

Studying strands polarity of different viroids and their combinations in infected hop plants
Acta Agriculturae Slovenica, 2020 Hop plant (Humulus lupulus L.) is an important industrial crop, grown for harvesting hop cones however, it is a host to four different viroids as well. The nature of viroid infections is not entirely clarified. In our work, we focused on analyzing viroid

Tropical Plant Pathology, 2009 Os viroides são os menores fitopatógenos conhecidos. Constituídos por uma molécula de RNA de fita simples, circular, que não é encapsidada e não codifica proteínas, são capazes de se replicar de maneira autônoma nas células do hospedeiro.

Peach latent mosaic viroid in naturally infected sweet cherry trees in southern Italy
International Journal of Horticultural Science, 2002 Peach latent mosaic viroid (PLMVd) was found in naturally infected sweet cherry trees grown in commercial orchards in southern Italy. The viroid was detected in nucleic acid extracts of symptomless leaves by molecular hybridization with a PLMVd cRNA ...

Suppression of RNA-Dependent RNA Polymerase 6 Favors the Accumulation of Potato Spindle Tuber Viroid in Nicotiana Benthamiana [PDF]
Viruses, 2019 To date, two plant genes encoding RNA-dependent RNA polymerases (RdRs) that play major roles in the defense against RNA viruses have been identified: (i) RdR1, which is responsible for the viral small RNAs (vsRNAs) found in virus-infected plants, and ...

Viroids: from genotype to phenotype just relying on RNA sequence and structural motifs [PDF]
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 ...

Genome-wide DNA methylation analysis of CBCVd-infected hop plants (Humulus lupulus var. “Celeia”) provides novel insights into viroid pathogenesis [PDF]
Microbiology SpectrumViroids are small, naked, infectious single-stranded RNA molecules that exploit host factors to replicate. Some viroids have been linked to severe diseases in agricultural crops, including the recent outbreak of Cocadviroid rimocitri, previously known as

Novel Viroid‐Like RNAs Naturally Infect a Filamentous Fungus
Advanced Science, 2023 To date, viroids have been found to naturally infect only plants, resulting in substantial losses for some crops. Whether viroids or viroid‐like RNAs naturally infect non‐plant hosts remains unknown.
