GUS Histochemical assay showing elicitation of the β-glucuronidase (GUS) reporter gene, put under the control of the pathogen-inducible CYP71A12 promoter (CYP71A12pro:GUS) in Arabidopsis thaliana (CYP71A12) following a 6-h treatment with various concentrations of Stella Maris®. Images were captured using the 20× objective lens. (a) Control seedling that was untreated. (b–d) were treated with 0.05%, 0.5% and 5%, respectively for 6 h prior to staining with GUS substrate solution. The experiments were repeated three times with the same result.
