Irradiating a solution of CBA produces a bioactive cytokinin. Two different solutions were uncaged in this experiment: 100 μM CA, and 100 μM CBA. Each solution was irradiated for one hour (see methods), then applied to the root tips of 7-day old A. thaliana seedlings, along with the negative controls of CA, CBA (which had not been irradiated) and solvent alone, and the positive control of 0.1 μM BA. The root growth of each cohort was measured after 24 h. Bold letters describe the results of a one-way ANOVA (Dunnett’s post-test, compared to solvent control group, P < 0.05), numbers in brackets correspond to the number of replicates in each treatment, and error bars depict standard deviation
