Figure 1. The prolonged juvenile phase of ch1 is suppressed by 35S::MIM156.
(A) Wild-type Col produces about six juvenile leaves (5.7 ± 0.9, N = 24) in SD conditions. (B) ch1-4 produces significantly more juvenile leaves (10.9 ± 0.8, N = 24, p<0.01) than Col. (C) 35S::MIM156. (D) ch1-4 35S::MIM156. This genotype has the morphology of 35S::MIM156 and the yellow-green phenotype of ch1-4; double mutants produced abaxial trichomes on leaf 1 and had elongated serrated leaves, demonstrating that the delayed phase change phenotype of ch1-4 is dependent on miR156. Numbers indicate the position from the base of the plant. Scale bar = 5 mm.
