We're starting a systematic study of targeting of a bunch of proteins
using this approach (for some early results see FEBS Lett. 431:39-44),
except we use transient expression in tobacco protoplasts rather than
transgenic plants. The vector we have now has two or three unique
restriction sites between the 35S promoter and the GFP coding sequence to
allow directional cloning of putative targeting sequences in frame with
the GFP. We'll be testing this modified vector next week...
