Cell cycle mutants. Germination and growth rate scoring based on the analysis of variance and Tukey test. The cycd2;1 had the highest growth rate, and e2fa-1 and cdkb1;1cdkb1;2 had the lowest. The number (N) of roots measured in each group of mutants for the wild-type (WT), e2fa-1, cdkb1;1cdkb1;2, and cycd2;1 was 60, 51, 59, and 49, respectively (total N = 219). N is the number of plants used in this study. In A, the y-axis represents the growth rate (mm/h). 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. Colored bars indicates the mutants analyzed 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. S10C complements C. Overlapping between roots first started at 53 h in the cycd2;1 mutants. Three biological replicates were tested using this system
