FIGURE 5.

Physiological analysis of transgenic plants under foliar application of glyphosate. Morphology of 21 days old transgenic ‘S,’ ‘D,’ and wt plants upon foliar application of 3 mL/L Roundup herbicide (A–C). The ‘D’ group transgenic lines showed higher glyphosate tolerance and possessed healthy and normal morphology comparable to wt(–) plants (A–C). However, the transgenic lines from ‘S’ group showed a significant foliar injury and yellow fleshing (A,B). wt(–) – wild type plants without glyphosate application; wt(+) – wild type plants with glyphosate application; S1, S2, and S3, ‘S’ transgenic lines; D1 and D3, ‘D’ transgenic lines.
