Auxin transport mutants. Germination and growth rate scoring based on the analysis of variance and Tukey test. The aux1 had the highest growth rate, and the mutants lax3, pin2, and pin2aux1 had the lowest growth rates (mm/h). The number (N) of roots measured in each group of mutants for the wild-type (WT), aux1, lax3, pin2, and pin2aux1 was 57, 60, 34, 64, and 61, respectively (total N = 276). 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. S10D complements C. Overlapping between roots first started at 67 h in the aux1 mutants. Three biological replicates were tested using this system
