FIG 3.

Both drh-1 and rsd-2 transgenes are functional in the ty48 transgene array. (A) Northern blot detection of FR1gfp replication in transgenic worm strains, as indicated, that contain the ty48 transgene array after heat induction. See the legend to Fig. 2B for experimental details. An asterisk indicates worms that were fed with E. coli food expressing drh-1 dsRNA. A double asterisk indicates worms that were fed with E. coli food expressing rsd-2 dsRNA. (B) Accumulation of Orsay virus RNA1 in drh-1 and rsd-2 mutants and wild-type N2 worms that carry the ty48 transgene array. An asterisk indicates worms that were fed with E. coli food expressing drh-1 dsRNA. A double asterisk indicates worms that were fed with E. coli food expressing rsd-2 dsRNA. See the legend to Fig. 2C for experimental details.
