Intrahemocoelic and oral infection experiments using these viruses revealed that the loss of functional vFGF reduces viral infectivity in B. mori hemocytes.[Ref7495:Katsuma et al., 2008]; 18611420 5097 orf74 548578271 orf74 Virulence factor the median lethal time of the orf74-knockout virus was 14.7 h longer than the control virus, but the virus yield was similar to that of control virus. Thus, our data indicated that ORF74 is most likely implicated in the virulence of BmNPV, and is not essential for virus replication. [Ref7498:Shen et al., 2009]; 19340569
