The aim of the present study was to determine the effect of three strains of Agrobacterium rhizogenes (ATCC 15834, A4 and LBA 9402) and the nature of explants (leaf and stem) on hairy root induction, growth and plumbagin production in Plumbago indica. The first appearance of hairy roots, the transformation frequency, dry root biomass and plumbagin accumulation were found to be maximum in hairy roots induced in leaf explants infected with A. rhizogenes ATCC 15834 as compared with the other two bacterial strains. The hairy roots generated from stem explants infected with all three strains were not found to be productive in terms of the selected parameters. Finally, the insertion of the rolB gene of A. rhizogenes ATCC 15834 in hairy roots of P. indica derived from leaf explants was confirmed by PCR analysis.
