Genomic support for speciation and specificity of baculoviruses

  title={Genomic support for speciation and specificity of baculoviruses},
  author={A. Jakubowska},
Keywords: baculovirus, insects, speciation, genomics, phylogeny, host specificity The Baculoviridae comprise a large family of double-stranded DNA viruses infecting arthropods. In this thesis two baculoviruses, Leucoma salicis nucleopolyhedrovirus (LesaNPV) and Agrotis segetum (Agse) NPV, were characterized in detail. Both viruses are potential biocontrol agents of the insects from which they were isolated. A close genetic relationship between LesaNPV and Orgyia pseudotsugata multiple NPV… Expand

Host range of two multiple nucleopolyhedroviruses isolated from Spodoptera litura
It is demonstrated that three species of Lepidoptera, S. litura and Spodoptera exigua and Arna pseudoconspersa belonging to the family Lymantriidae, died of NPV infection, indicating that the application ofNPV may have impact on nontarget Lepidptera with latent viral infections. Expand
Genetically variable nucleopolyhedroviruses isolated from spatially separate populations of the winter moth Operophtera brumata (Lepidoptera: Geometridae) in Orkney.
A lepidopteran system in which a pathogen is both abundant and genotypically variable is reported, showing encouraging results for further studies into the role of pathogens in the regulation of host insect populations. Expand
Phylogenetic interrelationships among baculoviruses: evolutionary rates and host associations.
This analysis indicates that lepidopteran NPV are clustered in at least two groups with distinct evolutionary rates and shows that the SNPV and MNPV morphotypes have to be taken with caution as classificatory traits since they appear to be unpolarized. Expand
Comparative study on the susceptibility of cutworms (Lepidoptera: Noctuidae) to Agrotis segetum nucleopolyhedrovirus and Agrotis ipsilon nucleopolyhedrovirus.
Since AgipNPV shows high virulence for both cutworm species, it appears to be a suitable candidate as a single biological control agent of A. segetum and A. ipsilon. Expand
The Baculoviruses Occlusion‐Derived Virus: Virion Structure and Function
The molecular biology of the ODV reveals new frontiers in protein chemistry and establishes infection in insect gut tissues that are virtually nonsupportive to virus replication and which are continuously sloughed away. Expand
Sequence and analysis of the genome of a baculovirus pathogenic for Lymantria dispar.
A number of homologs of genes not previously reported for baculoviruses were identified, including a predicted protein with homology to DNA ligases and another that has motifs most closely related to a yeast mitochondrial helicase. Expand
Genomic sequence, organization and characteristics of a new nucleopolyhedrovirus isolated from Clanis bilineata larva
The complete genome of Clanis bilineata nucleopolyhedrovirus (ClbiNPV) has been sequenced and analyzed in order to understand this virus better and is most closely related to Orle NPV, LdMNPV, TnSNPV, EcobNPV and ChchNPV. Expand
The genome sequence and evolution of baculoviruses.
Comparative analysis of the complete genome sequences of 13 baculoviruses revealed a core set of 30 genes, 20 of which have known functions, which provided evidence for two putative DNA repair systems and for viral proteins specific for infection of lymantrid hosts. Expand
Characterization of a nucleopolyhedrovirus from the vapourer moth, Orgyia antiqua (Lepidoptera Lymantriidae).
Transmission electron microscopy revealed that the virus nucleocapsid rods were singly enveloped in the polyhedron inclusion body (PIB) so that theirus is assigned to the SNPV subgenus of the Baculoviridae. Expand
European Leucoma salicis NPV is closely related to North American Orgyia pseudotsugata MNPV.
A multicapsid nucleopolyhedrovirus isolated from L. salicis larvae in Poland was characterized and appeared to be a variant of Orgyia pseudotsugata (Op) MNPV, suggesting a close relationship between LesaNPV and OpMNPV. Expand
