Analagous population structures for two alphabaculoviruses highlight a functional role for deletion mutants
Serrano García, Amaya; Williams, Trevor
; Simón de Goñi, Oihane
; López Ferber, Miguel; Caballero Murillo, Primitivo
; Muñoz Labiano, Delia
(American Society for Microbiology, 2012) Artículo / Artikulua
A natural Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) isolate from Florida shares a strikingly similar genotypic composition to that of a natural Spodoptera frugiperda MNPV (SfMNPV) isolate from Nicaragua. ... -
Expression of a peroral infection factor determines pathogenicity and population structure in an insect virus
Simón de Goñi, Oihane; Williams, Trevor
; Cerutti, Martine; Caballero Murillo, Primitivo
; López Ferber, Miguel (Public Library of Science, 2013) Artículo / Artikulua
A Nicaraguan isolate of Spodoptera frugiperda multiple nucleopolyhedrovirus is being studied as a possible biological insecticide. This virus exists as a mixture of complete and deletion genotypes; the latter depend on ... -
Functional importance of deletion mutant genotypes in an insect nucleopolyhedrovirus population
Simón de Goñi, Oihane; Williams, Trevor
; López Ferber, Miguel; Caballero Murillo, Primitivo
(American Society for Microbiology, 2005) Artículo / Artikulua
A Nicaraguan isolate of a nucleopolyhedrovirus (SfNIC) that attacks the fall armyworm, Spodoptera frugiperda, survives as a mixture of nine genotypes (SfNIC A to I) that all present genomic deletions, except variant B ... -
Gender-mediated differences in vertical transmission of a nucleopolyhedrovirus
Virto Garayoa, Cristina; Zárate Chaves, Carlos Andrés; López Ferber, Miguel; Murillo Pérez, Rosa
; Caballero Murillo, Primitivo
; Williams, Trevor
(Public Library of Science, 2013) Artículo / Artikulua
With the development of sensitive molecular techniques for detection of low levels of asymptomatic pathogens, it becoming clear that vertical transmission is a common feature of some insect pathogenic viruses, and likely ... -
Genetic structure of a Spodoptera frugiperda nucleopolyhedrovirus population: high prevalence of deletion genotypes
Simón de Goñi, Oihane; Williams, Trevor
; López Ferber, Miguel; Caballero Murillo, Primitivo
(American Society for Microbiology, 2004) Artículo / Artikulua
A Nicaraguan field isolate (SfNIC) of Spodoptera frugiperda nucleopolyhedrovirus was purified by plaque assay on Sf9 cells. Nine distinct genotypes, A to I, were identified by their restriction endonuclease profiles. Variant ... -
Mixtures of complete and pif1- and pif2-deficient genotypes are required for increased potency of an insect nucleopolyhedrovirus
Clavijo Palacios, Gabriel; Williams, Trevor
; Simón de Goñi, Oihane
; Muñoz Labiano, Delia
; Cerutti, Martine; López Ferber, Miguel; Caballero Murillo, Primitivo
(American Society for Microbiology, 2009) Artículo / Artikulua
The insecticidal potency of a nucleopolyhedrovirus population (SfNIC) that infects Spodoptera frugiperda (Lepidoptera) is greater than the potency of any of the component genotypes alone. Occlusion bodies (OBs) produced ... -
Optical brighteners do not influence covert baculovirus infection of Spodoptera frugiperda
Martínez Castillo, Ana Mabel; Williams, Trevor
; López Ferber, Miguel; Caballero Murillo, Primitivo
(American Society for Microbiology, 2005) Artículo / Artikulua
Covert infection with Spodoptera frugiperda multiple nucleopolyhedrovirus, detected by reverse transcription-PCR of virus gene transcripts (ie-0 and polh), was not significantly affected by the presence of an optical ... -
Regulation of multiple infection in alphabaculoviruses: critical factors that determine success
This thesis is focused in the ability of different baculovirus species to coinfect a particular host. I investigate whether the co-occlusion of different species is allowed and if it confers some advantage to the viruses, ... -
The sf32 unique gene of spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV) is a non-essential gene that could be involved in nucleocapsid organization in occlusion-derived virions
Beperet Arive, Inés; Barrera Cubillos, Gloria Patricia; Simón de Goñi, Oihane
; Williams, Trevor
; López Ferber, Miguel; Gasmi, Laila; Herrero, Salvador; Caballero Murillo, Primitivo
(Public Library of Science, 2013) Artículo / Artikulua
A recombinant virus lacking the sf32 gene (Sf32null), unique to the Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV), was generated by homologous recombination from a bacmid comprising the complete viral genome ... -
Stability of a Spodoptera frugiperda nucleopolyhedrovirus deletion recombinant during serial passage in insects
Simón de Goñi, Oihane; Williams, Trevor
; Possee, Robert D.; López Ferber, Miguel; Caballero Murillo, Primitivo
(American Society for Microbiology, 2009) Artículo / Artikulua
The stabilities of the Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV) complete genome bacmid (Sfbac) and a deletion recombinant (Sf29null) in which the Sf29 gene was replaced by a kanamycin resistance ... -
Superinfection exclusion in alphabaculovirus infections is concomitant with actin reorganization
Beperet Arive, Inés; Irons, Sarah L.; Simón de Goñi, Oihane
; King, Linda A.; Williams, Trevor
; Possee, Robert D.; López Ferber, Miguel; Caballero Murillo, Primitivo
(American Society for Microbiology, 2014) Artículo / Artikulua
Superinfection exclusion is the ability of an established virus to interfere with a second virus infection. This effect was studied in vitro during lepidopteran-specific nucleopolyhedrovirus (genus Alphabaculovirus, family ...
