  1. Cytokinin content was measured in root and shoot samples from 6-d-old seedlings grown on standard ½ MS medium. Values are in pmol g−1 fresh weight. Data are mean ± S.D. (n = 5 biologically independent samples). Asterisks indicate statistically significant differences from wild type (two-sided two sample t test without adjustments for multiple comparisons; *p < 0.05, **p < 0.01, ***p < 0.01). See Supplementary Table 1 for levels of individual cytokinin metabolites. Exact p values are provided in Supplementary Data 1.
  2. tZ trans-zeatin, iP isopentenyladenine, cZ cis-zeatin, DHZ dihydrozeatin.
