5131 18K 557798815 557798816 AHA36956.1 18K immediate early protein Virulence factor By successive rounds of selection for puromycin resistance and GFP expression, we have successfully constructed three recombinant viruses. In one, a "knock-in" mutant was created by inserting the Puro-EGFP cassette into a noncoding region of the FV3 genome (FV3-Puro/GFP). In the remaining two, KO mutants were constructed by replacement of the truncated viral homolog of eIF-2α (FV3-ΔvIF-2α) or the 18K IE gene (FV3-Δ18K) with the Puro-EGFP cassette Viral replication of each recombinant in cell culture was similar to that of parental FV3; however, infection in Xenopus laevis tadpoles revealed that FV3-ΔvIF-2α and FV3-Δ18K replicated less and resulted in lower mortality than did GFP-FV3 and wild-type FV3. Our results suggest that 18K, which is conserved in all ranaviruses, and the truncated vIF-2α gene contribute to virulence. (Chen et al., 2011) 21865381
