intron-GFP?

[alec forsyth]

We are interested in assaying transient expression from TDNA in tissue infiltrated 
with Agrobacterium.  Our control for TDNA transfer is a form of GUS with an intron in 
it - so we know blue color is not due to expression in the Agro.  However it would 
probably suit us better to use green fluorescent protein, because the assay is 
non-invasive.  Does anyone know if an intron-GFP (for plants) exists?
Thankyou very much (in advance) for your help
