Two point mutations (T2739C and C2910A, coordinates of nucleotides substitutions relative to RNA1 sequence) that disrupt the open reading frame (amino acid substitutions M1T and S58term).
FHV\ARNA1.UAS, FHV\B2RNA1Δ.UAS, FHV\gp1RNA2.UAS, Scer\GAL4yolk has viable phenotype
Animals co-expressing FHV\ARNA1.Scer\UAS, FHV\B2RNA1Δ.Scer\UAS and FHV\gp1RNA2.Scer\UAS under the control of Scer\GAL4yolk are viable. These animals are more resistant to infection with Flock House virus than wild-type controls.
