Abstract:
Transient expression using protoplasts isolated from Arabidopsis suspension culture cells is a fast and useful tool for analyzing protein subcellular localization and dynamics in plant cells. Recently, super-resolution imaging techniques such as N-SIM (Nikon, Structured Illumination Microscopy) are widely used in cell biology study, allowing cell biologists to obtain unattainable details and relationships of cell structures and functions by conventional confocal imaging. To facilitate the usage of protoplasts transient expression and super-resolution imaging for protein localization and dynamic analysis in plant cell biology research, here we describe updated protocols of protoplasts isolation from Arabidopsis suspension culture cells and transient expression assay for protein trafficking and localization study. Further, using GFP-tagged ERES (Endoplasmic Reticulum Exit Site) marker proteins and RFP-tagged Golgi marker as examples, we illustrate the major tools and methods for protein localization analysis using super-resolution imaging.

Protein Dynamics in Living Cells
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...
