In vitro transactivation of baculovirus early genes by nuclear extracts from Autographa californica nuclear polyhedrosis virus-infected Spodoptera frugiperda cells.
Nuclear extracts, prepared from Autographa californica nuclear polyhedrosis virus-infected Spodoptera frugiperda cells during a time course of infection, were analyzed for activation of early gene transcription and for late gene transcription. The templates used in the in vitro transcription assays contained promoters for baculovirus genes that have been classified as immediate early, delayed e...
متن کاملNucleotide sequence and transcriptional analysis of the polyhedrin gene of Spodoptera exigua nuclear polyhedrosis virus.
The nucleotide sequence of a 1.1 kbp fragment of the multiple nucleocapsid nuclear polyhedrosis virus (MNPV) of Spodoptera exigua (Se) containing the polyhedrin gene was determined. An open reading frame (ORF) of 738 nucleotides (nt) was detected. This ORF encoded a protein of 246 amino acids with a predicted M(r) of 29K. The nucleotide and amino acid sequences were compared with the sequences ...
متن کاملNucleotide sequence and transcriptional analysis of the p10 gene of Spodoptera exigua nuclear polyhedrosis virus.
The p10 gene of Spodoptera exigua multiple nuclear polyhedrosis virus (SeMNPV) was localized on the XbaI fragment H (5.1 kb) of the physical map of the viral genome. The coding sequence of the SeMNPV p10 gene is 264 nucleotides (nt) long corresponding to a predicted protein of 88 amino acids with an MHF of 9607. The SeMNPV p10 protein showed only limited amino acid identity (39% and 26%, respec...
متن کاملViral Transcription During Autographa californica Nuclear Polyhedrosis Virus Infection: a Novel RNA Polymerase Induced in Infected Spodoptera frugiperda Cells.
Autographa californica nuclear polyhedrosis virus-specific RNA synthesis in isolated nuclei of Spodoptera frugiperda cells in culture was monitored at different times postinfection. Up to 8 h postinfection viral RNA synthesis remained sensitive to 5 mug of alpha-amanitin per ml. During the course of infection this sensitivity decreased, and at 24 h postinfection RNA synthesis was completely res...
متن کاملIsolation of Herpetosiphon giganteus and Ultrastructure Analysis by Electron Microscopy
Herpetosiphon giganteus is a filamentous gliding bacterium. Gliding motility is the movement of the cells over surfaces without the aid of flagella. The mechanism responsible for bacterial gliding motility has not been known and there are only a few data on Herpetosiphon giganteus. The aim of this study was to observe the ultrastructure and negative staining of isolated strains of Herpetosiphon...
