Systemic Infection of Nicotiana benthamiana with Potato virus X Nanoparticles Presenting a Fluorescent iLOV Polypeptide Fused Directly to the Coat Protein

Figure 4

Detection of green fluorescence in epidermal cells from N. benthamiana leaves systemically infected with pPVX-iLOV-CP and pPVX-iLOV-2A-CP. The iLOV fluorescence was observed by confocal laser scanning microscopy. The hybrid particles indicate cell-to-cell movement at plasmodesmata (PD) and viral replication complexes (VRCs). For iLOV-2A-CP there is also free iLOV visible in the cytoplasm (). N: nucleus.
