Abstract

The detailed analysis of the expression pattern of a plant gene can give important clues about its function in plant development, cell differentiation and defence reactions. Gene expression studies have been greatly facilitated by the employment of proteins like β-glucuronidase (GUS), green fluorescent protein (GFP), and firefly luciferase (LUC) as reporters of gene activity. The application of reporter genes in plants, specifically in the field of gene expression studies, has expanded over the years from a mere tool to quantify (trans) gene expression in tissue samples, to real-time imaging of in planta promoter dynamics. To correctly interpret the activity that is given by each reporter, it is important to have a good understanding of the intrinsic properties of the different reporter proteins. Here we discuss those properties of GUS, LUC and GFP that are of interest in gene expression studies.

Key words
