Compromised function of RAP2.6L affects shoot regeneration in the amp1 mutant. A, Representative root explants of the indicated genotypes after 18 d on shoot induction medium. B, Quantification of shoot regeneration of the indicated genotypes. Bars for plant lines in the wild-type background are colored in dark gray, and bars for lines in the amp1-1 background are colored in light gray. The regenerative capacity was calculated as the number of shoots/cm root explant (bars represent means ± se; n ≥ 30). Different letters over the error bars indicate significant differences (P < 0.05) as estimated by Duncan’s multiple range test. Bars = 10 mm.
