Expanding Reverse Genetics of Positive-Strand RNA Viruses: Optimised Rescue Platforms and Construction of a Novel Fluorescent Reporter Nidovirus
It is demonstrated that a potent constitutive promoter system and a hammerhead ribozyme enhance the efficiency of positive-sense RNA virus rescue using CPER, and may support applications requiring efficient recovery of low fitness mutants and diverse mutational libraries and barcoded virus populations.
