Análisis de las interacciones moleculares del supresor del silenciamiento por RNA del virus del arabesco del Pelargonium

Pérez Cañamás, Miryam (Universitat Politècnica de València, 2015-07-27)

[EN] RNA silencing processes play an essential role in plant responses against exogenous nucleic acids such as transgenes, transposons or viruses. Viral-derived double-stranded RNAs (dsRNAs) trigger this type of processes ...
Characterization of horizontal evolution of RNA viruses using topological data analysis

Díaz Jordá, Teresa (Universitat Politècnica de València, 2020-10-13)

[ES] Los virus de ARN son conocidos agentes causantes de algunas enfermedades graves en los seres humanos como la influenza, el VIH, la hepatitis C, Ébola, SARS, MERS o el reciente brote de la COVID19. La evolución de estos ...
Effect of host species on the distribution of mutational fitness effects for an RNA virus

Lalic ., Jasna; CUEVAS, J.M; Elena Fito, Santiago Fco (Public Library of Science, 2011-10-17)

Knowledge about the distribution of mutational fitness effects (DMFE) is essential for many evolutionary models. In recent years, the properties of the DMFE have been carefully described for some microorganisms. In most ...
Epigenetic Changes in Host Ribosomal DNA Promoter Induced by an Asymptomatic Plant Virus Infection

Pérez-Cañamás, Miryam; Hevia, Elizabeth; HERNANDEZ FORT, CARMEN (MDPI AG, 2020-04)

[EN] DNA cytosine methylation is one of the main epigenetic mechanisms in higher eukaryotes and is considered to play a key role in transcriptional gene silencing. In plants, cytosine methylation can occur in all sequence ...
Genetic evidence for the involvement of Dicer-like 2 and 4 as well as Argonaute 2 in the Nicotiana benthamiana response against Pelargonium line pattern virus

Pérez-Cañamás, Miryam; Hevia, Elizabeth; HERNANDEZ FORT, CARMEN; Katsarou, Konstantina (Microbiology Society, 2021)

[EN] In plants, RNA silencing functions as a potent antiviral mechanism. Virus-derived double-stranded RNAs (dsRNAs) trigger this mechanism, being cleaved by Dicer-like (DCL) enzymes into virus small RNAs (vsRNAs). These ...
Interaction network of tobacco etch potyvirus NIa protein with the host proteome during infection

Martinez Roberto, Fernando; Rodrigo Tarrega, Guillermo; Aragones, Verónica; Ruiz Server, Marta; Lodewijk, Iris; Fernandez, Unai; Elena Fito, Santiago Fco; Daros Arnau, Jose Antonio (BioMed Central, 2016-02-01)

Conclusions: Potyviral NIa targets many host elements during infection, establishing a network in which information is efficiently transmitted.
Shrinkage of genome size in a plant RNA virus upon transfer of an essential gene into the host genome

Tromas, Nicolas; Zwart, Mark Peter; Forment Millet, José Javier; Elena Fito, Santiago Fco (Oxford University Press, 2014)

[EN] Nonretroviral integrated RNA viruses (NIRVs) are genes of nonretroviral RNA viruses found in the genomes of many eukaryotic organisms. NIRVs are thought to sometimes confer virus resistance, meaning that they could ...
Testing the Independent Action Hypothesis of Plant Pathogen Mode of Action: A Simple and Powerful New Approach

Zwart, Mark Peter; Elena Fito, Santiago Fco (American Phytopathological Society, 2015-01)

[EN] The independent action hypothesis is a simple model of pathogen infection that can make many useful predictions on infection kinetics and, therefore, a number of different tests of independent action have been developed. ...
Variability in mutational fitness effects prevents full lethal transitions in large quasispecies populations

Sardanyes Cayuela, Jose; Simó, Carles; Martínez, Regina; Solé, Ricard V.; Elena Fito, Santiago Fco (Nature Publishing Group, 2014-04-09)

[EN] The distribution of mutational fitness effects (DMFE) is crucial to the evolutionary fate of quasispecies. In this article we analyze the effect of the DMFE on the dynamics of a large quasispecies by means of a ...
