Ectopic expression of 19C07 in Arabidopsis leads to earlier lateral root emergence. A and B, Initial lateral root emergence of lax3 and LAX3-YFP (A) and lax3 and LAX3-YFP × 19C07 6-13-3 overexpression line 5 d after seeding (T = 0) through 8 d after seeding (T = 72 h). Bars = 100 μm. C, The number of LAX3-YFP sites of expression on 7- and 11-d-old seedlings. Lateral root initiation sites were counted on two replicates of two vertical plates seeded with six individuals for each line. No significant difference was found using a two-tailed t test. Error bars indicate se.
