Figure 1

Single-plane confocal micrographs of GFP: protein fusions expressed transiently in leaf epidermal cells of N. benthamiana plants transgenic for the nuclear marker, RFP: histone 2B. Shown in panels 1, 2, and 3 are micrographs of GFP (fusions), RFP, and the resultant overlay, respectively. (A1–A3) GFP only. (B1–B3) PYDV-N. (C–L) PYDV-N site-directed double mutants. Numbers indicate the amino acid residue in the full-length N protein where a two-residue change to alanine was introduced. Changes to glycine were made in cases where the residue was alanine in the native protein. Scale bar = 10 μm.
