Genomic diversity in European Spodoptera exigua multiple nucleopolyhedrovirus isolates.
Key virus traits such as virulence and transmission strategies rely on genetic variation that results in functional changes in the interactions between hosts and viruses. Here, comparative genomic analyses of seven isolates of Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) with differing phenotypes were employed to pinpoint candidate genes that may be involved in host-virus interactio...
متن کاملInteractions between Meteorus pulchricornis and Spodoptera exigua Multiple Nucleopolyhedrovirus
Baculoviruses may interact with parasitoids in the same host. A previous study has shown that infection of larvae with Spodoptera litura nucleopolyhedrovirus (SpltNPV) was deleterious to the survival and development of Meteorus pulchricornis (Wesmael) (Hymenoptera: Braconidae). In this paper, the interactions between M. pulchricornis and Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) ...
متن کاملGenetic and phenotypic variability in Spodoptera exigua nucleopolyhedrovirus isolates from greenhouse soils in southern Spain
Genotypic and phenotypic variation of SeMNPV was examined in seven isolates of SeMNPV originating from occlusion body (OB) populations in the soil of greenhouses in Spain. Semi-quantitative PCR indicated that some of the isolates were composed of a single dominant genotype, whereas other isolates were composed of two or three genotypes in equal proportions. The coexistence of genotypes could be...
متن کاملSequence and organization of the Spodoptera exigua multicapsid nucleopolyhedrovirus genome.
The nucleotide sequence of the DNA genome of Spodoptera exigua multicapsid nucleopolyhedrovirus (SeMNPV), a group II NPV, was determined and analysed. The genome contains 135611 bp and has a G+C content of 44 mol%. Computer-assisted analysis revealed 139 ORFs of 150 nucleotides or larger; 103 have homologues in Autographa californica MNPV (AcMNPV) and a further 16 have homologues in other bacul...
متن کاملThe F protein of Helicoverpa armigera single nucleopolyhedrovirus can be substituted functionally with its homologue from Spodoptera exigua multiple nucleopolyhedrovirus.
F proteins of group II nucleopolyhedroviruses (NPVs) are envelope fusion proteins essential for virus entry and egress. An F-null Helicoverpa armigera single nucleocapsid NPV (HearNPV) bacmid, HaBacDeltaF, was constructed. This bacmid could not produce infectious budded virus (BV) when transfected into HzAM1 cells, showing that F protein is essential for cell-to-cell transmission of BVs. When H...
