Figure 3. RNA gel blot analysis of GSA siRNA in agroinfiltrated WT and manifestation of PTGS in newly emerged leaves.
(a) IL after 7 days of agroinfiltration and newly emerged L1 were used as agroinfiltrated leaves and newly emerged leaves, respectively. The numbers in the result of agroinfiltrated leaves indicate the relative levels of 24-nt siRNA calculated the respective rRNA signal intensities. (b) Leaves developed newly from shoot apex at the 14 days post infiltration are arranged digitally for an easy comprehensible manner.
