Direct visualization of the native structure of viroid RNAs at single-molecule resolution by atomic force microscopy

Moreno, M.; Vázquez, L.; López Carrasco, A.; Martín-Gago, J. A.; FLORES PEDAUYE, RICARDO; Briones, C. (Landes Bioscience, 2019)

[EN] Viroids are small infectious, non-protein-coding circular RNAs that replicate independently and, in some cases, incite diseases in plants. They are classified into two families: Pospiviroidae, composed of species that ...
Dissecting the secondary structure of the circular RNA of a nuclear viroid in vivo: A "naked" rod-like conformation similar but not identical to that observed in vitro

López-Carrasco, María Amparo; Flores Pedauye, Ricardo (Landes Bioscience, 2017)

[EN] With a minimal (250-400nt), non-protein-coding, circular RNA genome, viroids rely on sequence/structural motifs for replication and colonization of their host plants. These motifs are embedded in a compact secondary ...
Ethylene is Involved in Symptom Development and Ribosomal Stress of Tomato Plants upon Citrus Exocortis Viroid Infection

Vázquez Prol, Francisco; López-Gresa, María Pilar; Rodrigo Bravo, Ismael; Belles Albert, José Mª; Lisón, Purificación (MDPI, 2020-05)

Identificación de los miembros de la familia Argonauta que unen a los pequeños RNAs derivados del viroide del tubérculo fusiforme de la patata

Minoia, Sofia (Universitat Politècnica de València, 2011-09-06)

Los viroides son pequeños RNAs circulares que no codifican proteína alguna. Las infecciones causadas por viroides en plantas inducen la acumulación de pequeños RNAs viroidales (vd-sRNAs) de 21-24 nt que presentan características ...

[EN] Ricardo Flores (1947-2020) focused his research on the identification, replication, pathogenesis, and evolution of viroids, the minimal non-protein-coding circular RNAs (250-400 nt) able to replicate and incite diseases ...
Interacción tomate-viroide: estudio del papel del snoRNA U3 y caracterización del volatiloma.

Balanzá Garcia, Marc (Universitat Politècnica de València, 2024-02-20)

[ES] Los viroides están constituidos por RNA circular de pequeño tamaño, no codificante, estructurado y monocatenario, pudiéndose considerar como los agentes infecciosos vegetales más pequeños conocidos hasta la fecha. En ...
Might exogenous circular RNAs act as protein-coding transcripts in plants?

Márquez-Molins, Joan; NAVARRO BOHIGUES, JOSE ANTONIO; Cervera Seco, Luis; Pallás Benet, Vicente; Gomez, Gustavo Germán (Landes Bioscience, 2021-10-15)

[EN] Circular RNAs (circRNAs) are regulatory molecules involved in the modulation of gene expression. Although originally assumed as non-coding RNAs, recent studies have evidenced that animal circRNAs can act as translatable ...
Next-generation sequencing and genome editing in plant virology

Hadidi, Ahmed; Flores Pedauye, Ricardo; Candresse, Thierry; Barba, Marina (Frontiers Media, 2016-08)

[EN] Next-generation sequencing (NGS) has been applied to plant virology since 2009. NGS provides highly efficient, rapid, low cost DNA, or RNA high-throughput sequencing of the genomes of plant viruses and viroids and of ...
