A. rhizogenes mediated transformation of A. aucheri; a hairy root induction on leaf explant after 3 weeks using strain ATCC 15834; b hairy root induction on leaf explant after 3 weeks using strain A4; c effect of different A. rhizogenes strains on frequency of hairy root induction in A. aucheri; The data were obtained as a mean of three replications. The different letters denote a statistically significant difference at P ≤ 0.05, as determined by Duncan’s multiple range test. Vertical lines represent standard errors
