GABBR1 and infection: In addition, plus-strand RNAα accumulation in infections with the γb1-127 and the γbI130G mutants (both of which eliminate suppression of RNA silencing) was more than two-fold higher than RNAα accumulation in the RNAα + RNAγΔγb or RNAα + RNAγγbATGm infections (Fig 5B, panels I and II, compare lanes 6 and 7 with lanes 4 and 5).
