Metadata about: For decades, the genetic modification of coronavirus genomes and the generation of recombinant coronaviruses have been hampered mostly due to the extraordinary large size of the coronaviral genome. The very first reverse genetic system for feline coronaviruses (FCoVs) was established in the early 2000s; the respective approach exclusively enabled the manipulation of the 3′-third of the viral genome. Later on, vaccinia virus- and bacterial artificial chromosome (BAC)-based systems have been developed. Both systems have the advantage that the entire FCoV genome is amenable for mutagenesis. The main focus of this chapter is the vaccinia virus-based reverse genetic system for FCoVs. Here we present protocols for (1) the generation of a full-length cDNA clone, (2) the manipulation of the FCoV genome, and (3) the rescue of recombinant FCoVs.
