Root stem cell regulator mutants. Germination and growth rate scoring based on the analysis of variance and Tukey test. The wild-type (WT) has the highest growth rate, followed by scr and Rbi, and shr exhibited the lowest growth rate (mm/h). The growth rate of each root (datapoint) is calculated as the slope of the fitted line for the entire growth cycle. The number (N) of roots measured in each group of mutants for the WT, scr, Rbi, and shr were 53, 55, 51, and 28, respectively (total N = 187). In A, the y-axis represents the growth rate (mm/h), and the x-axis represents different mutants. In B, the y-axis represents the root length (mm), and the x-axis indicates the duration of root growth in hours. C represents the hourly growth rate throughout the growth cycle; the x-axis represents the time point of growth of each mutant. Colored bars indicate the mutants analyzed. Additional file 1: Fig. S10A complements C. Overlapping between roots first started at 49 h in the WT group. Three biological replicates were tested using this system
