Fig. 3: CEP and cytokinin signalling pathways intersect.
From: CEP peptide and cytokinin pathways converge on CEPD glutaredoxins to inhibit root growth
a Representative images and b relative primary root length for Col-0 and cepr1-3 in response to increasing concentrations of tZ (0, 10, 100 nM) at 12 dg. Root length expressed as a percentage of seedlings grown on medium without tZ for each respective genotype (n = 7 plants). c CEP and tZ signalling is defective in cepr1-3. Primary root length was measured for Col-0 and cepr1-3 plants grown on medium containing CEP3 (1 µM), tZ (10 nM), combined CEP3 and tZ, or control medium (no CEP or tZ) for 12 days (n = 7 plants). Root length expressed as a percentage of the control plants. Letters represent significant differences (ANOVA followed by Tukey HSD test, p < 0.05). Scale bar = 1 cm. Box plot centre line, median; box limits, upper and lower quartiles; whiskers, 1.5x interquartile range. See Supplementary Fig. 6 for associated absolute root growth measurements and representative images. Exact p values are provided in the Source Data file.
