Organelle motility in plant cells: imaging golgi and ER dynamics with GFP.

By the addition of plant or mammalian targeting sequences, green fluorescent protein (GFP) can be directed to the endoplasmic reticulum, the Golgi apparatus, or both organelles in plant cells. This unit describes the application of rapid Agrobacterium and virus-mediated transient expression systems in leaf tissue to permit visualization of ER and Golgi dynamics in vivo by epifluorescence or confocal microscopy
