RT-PCR amplification of the manA gene from three transgenic lines and non-transgenic control plants. Arrow shows the amplified 550 bp manA fragment. Lanes M: GeneRuler 1-kb DNA Ladder (SM0311); B: blank control (water); non-transgenic control plants from seed-cane (wt) and tissue-cultured (tc) plants; transgenic lines (tp-29, tp-13, and tp-7)
