A plasmid-based reverse genetics system for influenza A virus.
A reverse genetics system for negative-strand RNA viruses was first successfully developed for influenza viruses. This technology involved the transfection of in vitro-reconstituted ribonucleoprotein (RNP) complexes into influenza virus-infected cells. We have now developed a method that allows intracellular reconstitution of RNP complexes from plasmid-based expression vectors. Expression of a ...
متن کاملGeneration of an Avian-Mammalian Rotavirus Reassortant by Using a Helper Virus-Dependent Reverse Genetics System.
UNLABELLED The genetic diversity of rotavirus A (RVA) strains is facilitated in part by genetic reassortment. Although this process of genome segment exchange has been reported frequently among mammalian RVAs, it remained unknown if mammalian RVAs also could package genome segments from avian RVA strains. We generated a simian RVA strain SA11 reassortant containing the VP4 gene of chicken RVA s...
متن کاملEstablishment of an entirely plasmid-based reverse genetics system for Bluetongue virus.
Bluetongue virus (BTV), the type species of the genus Orbivirus within the family Reoviridae, has a genome consisting of 10 linear double-stranded RNA genome segments. Current reverse genetics approaches for engineering the BTV genome rely upon in vitro synthesis of capped RNA transcripts from cloned cDNA corresponding to viral genome segments. In an effort to expand the utility of BTV reverse ...
متن کاملReverse genetics of rotavirus.
The genetics of viruses are determined by mutations of their nucleic acid. Mutations can occur spontaneously or be produced by physical or chemical means: for example, the application of different temperatures or mutagens (such as hydroxylamine, nitrous acid, or alkylating agents) that alter the nucleic acid. The classic way to study virus mutants is to identify a change in phenotype compared w...
متن کاملPlasmid-based human norovirus reverse genetics system produces reporter-tagged progeny virus containing infectious genomic RNA.
Human norovirus (HuNoV) is the leading cause of gastroenteritis worldwide. HuNoV replication studies have been hampered by the inability to grow the virus in cultured cells. The HuNoV genome is a positive-sense single-stranded RNA (ssRNA) molecule with three open reading frames (ORFs). We established a reverse genetics system driven by a mammalian promoter that functions without helper virus. T...
