Sequence 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 کاملCharacterization of Spodoptera exigua multicapsid nucleopolyhedrovirus ORF17/18, a homologue of Xestia c-nigrum granulovirus ORF129.
Spodoptera exigua multicapsid nucleopolyhedrovirus (SeMNPV) contains a number of genes with a homologue found so far only in a distantly related baculovirus. One of these, SeMNPV ORF17/18 (Se17/18) shares 55% amino acid similarity to ORF129 of Xestia c-nigrum granulovirus (XcGV). Se17/18 was transcribed in cultured S. exigua 301 cells, as a polyadenylated transcript of 1.1 kb. 5'-RACE analysis ...
متن کاملA New Continuous Cell Line of Spodoptera exigua and Its Susceptibility to Autographa californica Multicapsid Nucleopolyhedrovirus
A continuous cell line, designated KU-SENL-1 (SENL1), has been established from minced neonate larvae of Spodoptera exigua (Lepidoptera: Noctuidae) treated with collagenase. The primary culture was maintained in TC100 medium supplemented with 10% Fetal Bovine Serum (FBS), 3% Helicoverpa armigera hemolymph and incubated at 27°C. This continuous cell line was cultured in TC100 medium supplemented...
متن کاملTranscriptional analysis and promoter activity of the Spodoptera littoralis multicapsid nucleopolyhedrovirus ecdysteroid UDP-glucosyltransferase gene.
The ecdysteroid UDP-glucosyltransferase gene (egt) of Spodoptera littoralis multicapsid nucleopolyhedrovirus (SpliMNPV) is a homologue of the Autographa californica MNPV (AcMNPV) egt gene, which has been found to block insect moulting. Infection of larvae with an egt-deleted AcMNPV resulted in enhanced mortality as compared to infection with the wild-type virus. Consequently, deletion of an egt...
متن کاملGenomic 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...
