Generation of a Recombinant Akabane Virus Expressing Enhanced Green Fluorescent Protein.

ABSTRACT:

Unlabelled

We generated a recombinant Akabane virus (AKAV) expressing enhanced green fluorescence protein (eGFP-AKAV) by using reverse genetics. We artificially constructed an ambisense AKAV S genome encoding N/NSs on the negative-sense strand, and eGFP on the positive-sense strand with an intergenic region (IGR) derived from the Rift Valley fever virus (RVFV) S genome. The recombinant virus exhibited eGFP fluorescence and had a cytopathic effect in cell cultures, even after several passages. These results indicate that the gene encoding eGFP in the ambisense RNA could be stably maintained. Transcription of N/NSs and eGFP mRNAs of eGFP-AKAV was terminated within the IGR. The mechanism responsible for this appears to be different from that in RVFV, where the termination sites for N
