Development of bdellophage VL-1 in parasitic and saprophytic bdellovibrios.

abstract：:The RNA-dependent RNA polymerase of influenza A virus is responsible for both transcription and replication of negative-sense viral RNA. It is thought that a "switching" mechanism regulates the transition between these activities. We demonstrate that, in the presence of preexisting viral RNA polymerase and nucleoprote...
