Abstract:
We describe a fluorescence imaging method to visualize the dynamics of the central vacuole in rice cells during invasion by the blast fungus Magnaporthe oryzae. This method utilizes the combination of confocal microscopy, rice sheath cells (optically transparent), fluorescently tagged M. oryzae (red fluorescence), and fluorescein diacetate staining (green fluorescence; visualizing vacuole dynamics). Using this method, we demonstrate that the vacuole undergoes progressive shrinkage and collapse during M. oryzae infection.

Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...
