X-Gluc is a chromogenic substrate for beta-glucuronidase (GUS) which is encoded by the gusA (uid A) gene, a widely used reporter gene. Glucuronidase cleaves X-Gluc to produce colorless glucuronic acid and an intense blue precipitate. X-Gluc is often used in GUS staining of plant cells and tissue and in infections caused by E. coli.
