The GUS reporter system is a widely used molecular biology technique that utilizes the β-glucuronidase (GUS) enzyme as a reporter gene to study gene expression in plants and some other organisms. The GUS gene is derived from the bacterium *Escherichia coli* and encodes an enzyme that catalyzes the cleavage of β-glucuronides, leading to the release of a colored product when specific substrates are used.
