Figure 8.
Confocal micrographs showing PYDV-N fragment interactions with PYDV-N determined by BiFC. Interaction assays were conducted in leaf epidermal cells of transgenic N. benthamiana expressing a fluorescent nuclear marker (Nucleus). Shown is the ability of fragments of PYDV-N to interact with wild-type N protein in BiFC assays. (A1–A3) GST. (B1–B3) Wild-type PYDV-N. (C–H) BiFC between PYDV-N and PYDV-N fragments F1–F6. The portions of PYDV-N used in the BiFC assays are indicated by the amino acid (aa) designation for each panel. Scale bar = 10 μm.
