a Pattern expression of WUS::3xVENUS-NLS at Col-0, ap2-12 and rAP2 SAMs of plants grown under continuous longs days (LDs). Each SAM is shown from the side. The outline of each acquired meristem and its peripheral organs is indicated with a dotted white line. Scale bar = 50 μm. b–c Quantification of the size of CLV3::mCHERRY-NLS domain (b) height and (c) width in Col-0, ap2-12 and rAP2 backgrounds. d–e Quantification of the size of WUS::3xVENUS-NLS domain (d) height and (e) width in Col-0, ap2-12 and rAP2 backgrounds. f Mean meristem periphery calculated subtracting WUS domain width (Fig. 3e) to the meristem width (Supplementary Fig. 6c) and dividing by 2 that difference. g Ratio of meristem periphery and WUS domain width in Col-0, ap2-12 and rAP2 backgrounds. The horizontal bars represent the median value for each genotype. Significant differences among genotypes within each time point were determined via two-sided Mann-Whitney-Wilcoxon test with the wild type and across the same genotype at different time points via one-way ANOVA (two-sided), followed by Tukey post-hoc comparisons (p < 0.05). For the ANOVA test, data sets that share a common letter do not differ significantly. The color of the dots and the letters correspond to the genotype. See Supplementary Data 7 for precise sample size and p-values of Mann-Whitney-Wilcoxon and ANOVA test. Source Data are provided as a Source Data file.
