3. PEG-mediated transformations of protoplasts from cell cultures or plants-mesophyl (Arabidopsis or tobacco).
4. Productions of cell cultures (wild type).

Protoplasts isolated from root cell culture are transformed with a 35S::GFP construct (12kb) as a routine control. As an alternative to calculating the transformation efficiency, we have used FCA as a means for detecting cells expressing GFP. The negative population is marked in black. Cells that are strongly expressing GFP have a fluoresence signal that is well above that of the total plant cell population‘s green autofluoresence (cells marked in dark green); cells marked in light green are those with weaker GFP fluoresence emission. In this example 23% of the cells were transformed with GFP, and 50% of those are strongly expressing GFP.
