A pospiviroid from symptomless portulaca plants closely related to iresine viroid 1

Verhoeven, J.TH J.; Roenhorst, JW; Hooftman, M; Meekes, E.T.M.; Flores Pedauye, Ricardo; Serra Alfonso, Pedro (Elsevier, 2015-07-02)

[EN] In symptomless plants of portulaca a potential new pospiviroid was characterized. Analysis by both double and return PAGE showed the presence of a circular RNA. RT-PCR and sequencing revealed a genome of 351 nt with ...
Apple hammerhead viroid-like RNA is a bona fide viroid: Autonomous replication and structural features support its inclusion as a new member in the genus Pelamoviroid

Serra Alfonso, Pedro; Messmer, A.; Sanderson, D.; James, D.; Flores Pedauye, Ricardo (Elsevier, 2018)

[EN] Apple hammerhead viroid-like RNA (AHVd RNA) has been reported in different apple cultivars and geographic regions and, considering the presence of hammerhead ribozymes in both polarity strands, suspected to be either ...
Dahlia latent viroid: a recombinant new species of the family Pospiviroidae posing intriguing questions about its origin and classification

Verhoeven, Jacobus Th. J.; Meekes, Ellis T. M.; Roenhorst, Johanna W.; Flores Pedauye, Ricardo; Serra Alfonso, Pedro (Microbiology Society, 2013-04)

[EN] A viroid-like RNA has been detected in two asymptomatic dahlia accessions by return and double PAGE. It appeared smaller than Chrysanthemum stunt viroid and Potato spindle tuber viroid, the two members of the genus ...
Estudios de Patogenicidad de Viroides del Género Apscaviroide y Hostuviroide en cítricos

Serra Alfonso, Pedro (Universitat Politècnica de València, 2009-07-17)

Estudios realizados en Atalantia citroides, un género afín de los cítricos, mostraron que estaba infectada con un viroide no descrito hasta el momento. Este nuevo viroide tiene un genoma de 293-294 nucleótidos con una alta ...
Interference between variants of peach latent mosaic viroid reveals novel features of its fitness landscape: implications for detection

Serra Alfonso, Pedro; Bertolini, Edson; Martinez, M. Carmen; Cambra, Mariano; Flores Pedauye, Ricardo (Nature Publishing Group, 2017)

[EN] Natural populations of peach latent mosaic viroid (PLMVd) are complex mixtures of variants. During routine testing, TaqMan rtRT-PCR and RNA gel-blot hybridization produced discordant results with some PLMVd isolates. ...
Molecular and phylogenetic identification of unique isolates of hammerhead viroid-like RNA from 'Pacific Gala' apple (Malus domestica) in Canada

Messmer, Amber; Sanderson, Daniel; Braun, Gordon; Flores Pedauye, Ricardo; Serra Alfonso, Pedro; James, Delano (Taylor & Francis, 2017)

[EN] Ten isolates of apple hammerhead viroid-like RNA (AHVd RNA) were detected by next-generation sequencing (NGS) and/or by RT-PCR analysis of apple (Malus domestica) 'Pacific Gala' (PG) from Canada. All consisted of 433 ...
Symptomatic plant viroid infections in phytopathogenic fungi: a request for a critical reassessment

Serra, Pedro; CARBONELL, ALBERTO; Navarro, Beatriz; Gago Zachert, Selma; Li, Shigang; Di Serio, Francesco; FLORES PEDAUYE, RICARDO (Proceedings of the National Academy of Sciences, 2020-05-12)
Viroids and Hepatitis Delta Virus

Flores Pedauye, Ricardo; Ruiz Ruiz, Susana; Serra Alfonso, Pedro (Thieme Publishing, 2012-08)

[EN] There is a subviral world, whose most prominent representatives are viroids. Despite being solely composed by a circular, highly structured RNA of 250 to 400 nucleotides without protein-coding ability (all viruses ...
Viroids: from genotype to phenotype just relying on RNA sequence and structural motifs

Flores Pedauye, Ricardo; Serra Alfonso, Pedro; Minoia, Sofia; Di Serio, Francesco; Navarro, Beatriz (Frontiers Media, 2012)

[EN] 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 ...
Viroids: survivors from the RNA world?

FLORES PEDAUYE, RICARDO; Gago Zachert, Selma Persida; SERRA ALFONSO, PEDRO; Sanjuan Verdeguer, Rafael; ELENA FITO, SANTIAGO FCO (Annual Reviews, 2014)

[EN] Because RNA can be a carrier of genetic information and a biocatalyst, there is a consensus that it emerged before DNA and proteins, which eventually assumed these roles and relegated RNA to intermediate functions. ...
