Stably transformed transgenic hairy root cultures have the potential to be a valuable production platform for a variety of secondary metabolites. This study reports that a transgenic hairy root culture of Catharanthus roseus has been stably maintained for over 4.5 years. This culture carries a transgene that expresses the green fluorescent protein under the control of the glucocorticoid-inducible promoter. Genomic PCR confirmed the presence of the GFP insert within the hairy roots, and induction with dexamethasone caused a significant (p < 0.02) increase in GFP levels.
