The precocious phenotype of meristem-defective mutants is not caused by a delay in leaf initiation. (A) The phenotype of WT Columbia and mutant plants at 23 DAP in LD conditions. White arrows point to leaves 1 and 2. (Scale bar, 5 mm.) (B and C) The angle of the leaf base (B) and the length:width ratio of the leaf blade (C) in leaves 1–5 of WT plants and in leaves 1 and 2 of meristem-defective mutants. Boxes display the interquartile range (IQR) (boxes), median (lines), and values beyond 1.5* IQR (whiskers); mean values are marked by a solid diamond (◆). Significantly distinct groups were determined by one-way ANOVA with post hoc Tukey multiple comparison test (letters indicate statistically distinct groups; P < 0.05). Sample sizes are shown on the graphs. (D) Distribution of leaf primordia number identified by staining of a LFY::GUS reporter in respective meristem-defective mutants (wus and stm were segregating 25% mutant plants; psd was homozygous for the mutation).
