Abstract
A precise and efficient protocol using computer image analysis for quantifying the area of explants that show stable expression of the GUS reporter gene is described. This protocol offers the advantages of quantifying results of the histochemical GUS assay thereby allowing statistical analysis of results, while still retaining information on tissue or organ-specific activity.
