Figure 1. Root formation induced by A. rhizogenes in intact seedling hypocotyls, de-rooted seedling cuttings, and adventitious shoots. (A) In intact seedlings, roots induced by strain LBA9402 and A4T. Arrows indicate injection sites. CT = control seedling.  (B) Roots induced by strain LBA9402 in a de-rooted seedling cutting. (C) Roots induced by strain LBA9402 in an adventitious shoot and a control shoot (CT).
