Figure 3From: Establishment of hairy root lines and analysis of iridoids and secoiridoids in the medicinal plant Gentiana scabraMolecular characterization of transgenic hairy roots. PCR confirmation of some selected transgenic hairy roots of G. scabra showing the amplification of (a) rol B gene amplification (780 bp) (b) and rol C gene amplification (540 bp). Lane M: Molecular weight marker; Lane Nt: non-transgenic line; Lane No. 1–5: transformed hairy root lines; P: positive control.Back to article page
