Glyphosate tolerance of transgenic tobacco seedlings on plates containing 1 mM glyphosate.

<p>T1 tobacco seeds were germinated on the MS medium containing 10 mg L⁻¹ PPT and grown for 7 days. The live seedlings were transferred to MS medium on plates containing 1 mM glyphosate. Photographs were taken two weeks later, and the fresh weight was measured at the same time. (A) Photograph of tobacco harboring <i>HTG7 aroA</i> and WT grown on the medium containing 1 mM glyphosate. (B) Photograph of tobacco harboring <i>AM79 aroA</i> and WT grown on the medium containing 1 mM glyphosate. (C) Photograph of tobacco harboring <i>A1501 aroA</i> and WT grown on the medium containing 1 mM glyphosate. (D) Photograph of tobacco harboring <i>RD aroA</i> and WT grown on the medium containing 1 mM glyphosate. (E) Photograph of tobacco harboring <i>G2 aroA</i> and WT grown on the medium containing 1 mM glyphosate. (F) Photograph of tobacco plants grown on the medium without glyphosate. (G) Fresh weight of the tobacco plants. Data are shown as the average ± S.E. of seven to ten independent transgenic lines. Experimental data was tested by ANOVA analysis and different letter in each column means significant difference at <i>P</i><0.05 level.
