Relative glyphosate resistance of OX, EV, and wild-type <i>Arabidopsis</i> lines, showing means ± 1 SE in Experiments A, B, and C at 21 days after spraying with glyphosate (1.0x or 0.5x).

<p>Sample sizes and other details are summarized in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0175820#pone.0175820.t001" target="_blank">Table 1</a>. Above-ground biomass (grams fresh weight) is shown for Experiment A. Visual damage scores are based on a scale of 0–5, with 0 for plants that died, and 5 for plants that were mostly green and were developing new leaves. Means that do not share superscripts are significantly different at p<0.05 (Tukey tests). NA indicates “not applicable” for lines that were not used in Experiments A and C.
