A membrane-associated movement protein of Pelargonium flower break virus shows RNA-binding activity and contains a biologically relevant leucine zipper-like motif

Martínez Turiño, Sandra; Hernandez Fort, Carmen (Elsevier, 2011)

[EN] Two small viral proteins (DGBp1 and DGBp2) have been proposed to act in a concerted manner to aid intra- and intercellular trafficking of carmoviruses though the distribution of functions and mode of action of each ...
An Internal Ribosome Entry Site Directs Translation of the 39-Gene from Pelargonium Flower Break Virus Genomic RNA: Implications for Infectivity

Fernandez Miragall, Olga; Hernandez Fort, Carmen (Public Library of Science, 2011)

[EN] Pelargonium flower break virus (PFBV, genus Carmovirus) has a single-stranded positive-sense genomic RNA (gRNA) which contains five ORFs. The two 59-proximal ORFs encode the replicases, two internal ORFs encode movement ...
Analysis of the subcellular targeting of the smaller replicase protein of Pelargonium flower break virus

Martínez Turiño, Sandra; Hernandez Fort, Carmen (Elsevier, 2012)

[EN] Replication of all positive RNA viruses occurs in association with intracellular membranes. In many cases, the mechanism of membrane targeting is unknown and there appears to be no correlation between virus phylogeny ...
Análisis de determinantes de localización subcelular en el supresor del silenciamiento por RNA codificado por el virus del arabesco del Pelargonium

Fajardo Flores, María del Pilar (2015-01-20)

[ES] En plantas, el silenciamiento por RNA constituye un potente mecanismo de defensa antiviral. Este mecanismo es activado por RNAs virales de doble cadena, producidos en el curso de la infección, que son reconocidos por ...
Análisis de la interacción del virus del arabesco del Pelargonium con la ruta de silenciamiento por RNA del huésped

Pérez Cañamás, Miryam (2019-11-08)

[ES] En plantas, el silenciamiento por RNA constituye un potente mecanismo de defensa frente a virus. Los RNA virales de doble cadena activan este tipo de procesos y son digeridos por las enzimas DCL (Dicer-like), cuya ...
Análisis de las interacciones moleculares del supresor del silenciamiento por RNA del virus del arabesco del Pelargonium

Pérez Cañamás, Miryam (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 ...
Análisis de mecanismos de acción del supresor del silenciamiento por RNA codificado por el virus del arrugamiento del nabo (Turnip crinkle virus, TCV)

Mestanza Mendoza, Marilu (2020-02-12)

[ES] El silenciamiento génico mediado por RNA es un sistema general de regulación de la expresión génica específico de secuencia que está conservado en eucariotas. Desde un punto de vista mecanístico, el proceso de ...
Análisis de procesos de transcripción, traducción y degradación del virus del arabesco del Pelargonium

Blanco Pérez, Marta (2017-02-08)

[EN] Pelargonium line pattern virus (PLPV) is one of the most frequent viral agents in geranium. It's an icosahedral virus, with a monopartite, positive-sense, single-stranded RNA genome, lacking a cap structure at the ...
Análisis de relaciones estructura-función en el virus del arabesco del Pelargonium.

Castaño Sansano, Mª Aurora (2009-07-17)

El virus del arabesco del Pelargonium (Pelargonium line pattern virus, PLPV) es el agente de tipo viral más frecuente en geranio (Pelargonium spp.), con porcentajes de incidencia en España que oscilan entre el 40 y el 90%, ...
ANÁLISIS FUNCIONAL DE PROTEÍNAS CODIFICADAS POR EL VIRUS DE LA ROTURA DEL COLOR DE LA FLOR DEL PELARGONIUM

Martínez Turiño, Sandra (2012-07-23)

Interés del estudio: El virus de la rotura del color de la flor del Pelargonium (Pelargonium flower break virus, PFBV) (género Carmovirus, familia Tombusviridae) constituye uno de patógenos virales más frecuentes en geranio, ...
Efficient Translation of Pelargonium line pattern virus RNAs Relies on a TED-Like 3 '-Translational Enhancer that Communicates with the Corresponding 5 '-Region through a Long-Distance RNA-RNA Interaction

Blanco Pérez, Marta; Pérez Cañamás, Miryam; Ruiz, Leticia; Hernandez Fort, Carmen (Public Library of Science, 2016-04-04)

[EN] Cap-independent translational enhancers (CITEs) have been identified at the 3'-terminal regions of distinct plant positive-strand RNA viruses belonging to families Tombusviridae and Luteoviridae. On the bases of their ...
Evidence supporting a premature termination mechanism for subgenomic RNA transcription in Pelargonium line pattern virus: identification of a critical long-range RNA-RNA interaction and functional variants through mutagenesis

Blanco Pérez, Marta; Hernandez Fort, Carmen (Microbiology Society, 2016-06)

Pelargonium line pattern virus (PLPV) is a plus-strand RNA virus that has been proposed as type species of a tentative new genus, Pelarspovirus, in the family Tombusviridae. One of the singular traits of members of this ...
Key importance of small RNA binding for the activity of a GW motif-containing RNA silencing suppressor
