Analysis of the accumulation of RNAs containing the EGFP gene. Protoplasts were inoculated with the following RNA combinations: T1 + T2 (a), T1-EG15 + T2 (b), T1-15Nh + T2 (c), T1-15Nh + T2 + TRep-15EG (d), T1-15Nh + T2 (e), T1-15Nh + T2 + TRep-EG15 (f). Blots were probed with the same 32P riboprobes as given for Fig. 3.
