Extended Data Figure 8. Phenotypic analysis of hormone-treated plants and mutants.

a) Root length of 5-day-old plants either germinated on increasing concentration of cytokinin (BA), auxin (NAA) or abscisic acid (ABA) (left) or of mutants used in this study (right). Open circles represent outliers. b) Emerged lateral roots per mm of 10-day-old Col-0 roots germinated in presence of DMSO, 10 nM cytokinin (BA) or 50 nM auxin (NAA) (left) or of mutants used in this study (right). Open circles represent outliers. c) Length of the root apical meristem of 5-day-old Col-0 plants germinated on either DMSO, 10 nM cytokinin (BA) or 50 nM auxin (NAA) (left) or of mutants used in this study (right). Dots represent individual datapoints. d) Onset of protoxylem and metaxylem after the elongation zone of 5-day-old seedling germinated in presence of DMSO, 10 nM cytokinin (BA) or 50 nM auxin (NAA) (left) or of mutants used in this study (right). Dots represent individual datapoints. ABA; Abscisic acid, BA; Benzyladenine, NAA; Naphtalene acetic acid. Bar graphs represent mean ± SD, boxplot centers show median. Individual letters show significantly different groups according to a post hoc Bonferroni-adjusted paired two-sided T-test. For more information on data plots see the statistics and reproducibility section. n represents independent biological samples. In a) ** Depicts significant difference (p<0,01) in a two-tailed T-test n = 25 independent biological replicas for each treatment.
