Cell-to-cell movement of P3N-PIPO-GFP in <i>N. benthamiana</i> leaves.

<p>(A) Images of epidermal cells expressing GFP alone or fused to P3N-PIPO (P3N-PIPO-GFP) at indicated hours post biolistic bombardment (hpb). Images are projections of single confocal section. (B) Quantification of cell-to-cell movement of GFP and P3N-PIPO-GFP. At least 160 GFP-expressing clusters in each bombarded sample were analyzed at 24 hpb and 48 hpb. At 48 hpb the number of cells in each cluster was counted, followed by statistical evaluation by the unpaired Student's <i>t</i>-test (P = 0.151). Error bars represent standard deviations.
