2b or not 2b: experimental evolution of functional exogenous sequences in a plant RNA virus

Willemsen, Anouk; Zwart, Mark Peter; Ambros Palaguerri, Silvia; Carrasco Jiménez, José Luis; Elena Fito, Santiago Fco (Oxford University Press, 2017)

[EN] Horizontal gene transfer (HGT) is pervasive in viruses and thought to be a key mechanism in their evolution. On the other hand, strong selective constraints against increasing genome size are an impediment for HGT, ...
Diminishing returns of inoculum size on the rate of a plant RNA virus evolution

Navarro, Rebeca; Ambros Palaguerri, Silvia; Martinez, Fernando; Elena Fito, Santiago Fco. (IOP Publishing - Europhysics Letters, 2017)

[EN] Understanding how genetic drift, mutation and selection interplay in determining the evolutionary fate of populations is one of the central themes of Evolutionary Biology. Theory predicts that by increasing the number ...
Engineered Functional Redundancy Relaxes Selective Constraints upon Endogenous Genes in Viral RNA Genomes

Ambros Palaguerri, Silvia; De la Iglesia Jordán, Francisca; Rosario, S.; Butkovic, Anamarija; Elena Fito, Santiago Fco (Oxford University Press, 2018)

[EN] Functional redundancy, understood as the functional overlap of different genes, is a double-edge sword. At the one side, it is thought to serve as a robustness mechanism that buffers the deleterious effect of mutations ...
ESTUDIO DE LA INTERACCIÓN DIFERENCIAL ENTRE AISLADOS DEL VIRUS DE LA TRISTEZA DE LOS CÍTRICOS (CTV) Y SUS HUÉSPEDES

Gómez Muñoz, Neus (Universitat Politècnica de València, 2018-01-15)

La tristeza es la enfermedad viral más grave del cultivo de los cÃtricos y su agente causal es el virus de la tristeza de los cítricos (CTV). CTV induce uno o más de los siguientes síndromes: I) decaimiento y muerte de ...
Estudio preliminar de las interacciones del virus de la tristeza de los cítricos (CTV) y su huésped

Navarro López, Josep Amadeu (Universitat Politècnica de València, 2017-11-06)

Citrus tristeza virus (CTV) is a viral species of the Closterovirus genus, having a ¿20 kb single-stranded and positive sense genomic RNA (gRNA) organized into 12 open reading frames (ORFs) potentially coding 17 protein ...
Evaluación del potencial de Caenorhabditis elegans como huésped experimental de arbovirus

González Miguélez, Rubén (Universitat Politècnica de València, 2017-02-08)

[EN] So far, Caenorhabditis elegans has been used as model organism in many different fields of study, but seldom used as experimental host in virology studies. The present work seeks to evaluate the potential of the ...
In memoriam of Ricardo Flores: The career, achievements, and legacy of an inspirational plant virologist

Pallás Benet, Vicente; HERNANDEZ FORT, CARMEN; Marcos, Jose F.; Daròs, José-Antonio; Ambrós, Silvia; Navarro, Beatriz; NAVARRO BOHIGUES, JOSE ANTONIO; La Peña Del Rivero, Marcos De; Gago-Zachert, Selma; Gas, Maria E.; CARBONELL, ALBERTO; López Del Rincón, Carmelo; Martínez-De Alba, Angel E.; Di Serio, Francesco; Moreno, Pedro (Elsevier, 2022-04-15)

[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 ...
Molecular and biological characterization of an isolate of Tomato mottle mosaic virus (ToMMV) infecting tomato and other experimental hosts in eastern Spain

Ambros Palaguerri, Silvia; Martinez, F.; Ivars, P.; Hernandez Fort, Carmen; De la Iglesia Jordán, Francisca; Elena Fito, Santiago Fco. (Springer-Verlag, 2017)

[EN] Tomato is known to be a natural and experimental reservoir host for many plant viruses. In the last few years a new tobamovirus species, Tomato mottle mosaic virus (ToMMV), has been described infecting tomato and ...
On the early identification and characterization of pear blister canker viroid, apple dimple fruit viroid, peach latent mosaic viroid and chrysanthemum chlorotic mottle viroid

Navarro, Beatriz; Ambros, Silvia; Di Serio, Francesco; HERNANDEZ FORT, CARMEN (Elsevier, 2023-01-02)

[EN] In the 90 ' s, pear blister canker viroid (PBCVd), apple dimple fruit viroid (ADFVd), peach latent mosaic viroid (PLMVd) and chrysanthemum chlorotic mottle viroid (CChMVd) were identified and characterized in the ...
Viral Fitness Correlates with the Magnitude and Direction o the Perturbation Induced in the Host's Transcriptome: The Tobacco Etch Potyvirus-Tobacco Case Study

Cervera-Benet, Héctor; Ambros Palaguerri, Silvia; Bernet, Guillermo P.; Rodrigo Tarrega, Guillermo; Elena Fito, Santiago Fco (Oxford University Press, 2018-07)

[EN] Determining the fitness of viral genotypes has become a standard practice in virology as it is essential to evaluate their evolutionary potential. Darwinian fitness, defined as the advantage of a given genotype with ...
Viroid diseases in pome and stone fruit trees and Koch s postulates: a critical assessment

Di Serio, Francesco; Ambros Palaguerri, Silvia; Sano, T; Flores Pedauye, Ricardo; Navarro, B (MDPI AG, 2018-11)
