Endogenous levels of cytokinins, gibberellin, ABA and auxins in a wild-type and gibberellin signaling mutants. Shoots of the wild type (T65) and gid1-3, gid2-1 and slr1 were harvested after growth in a greenhouse for 5 weeks. The amounts of the hormones are shown as histograms with the SD (n = 3). The y-axis is concentration as pmol g−1 FW. Hormone species and other compounds in gray were not measured, and those in black were under the quantification limit. The overall recoveries of analyzed stable isotope-labeled internal standards are presented in Supplementary Table S7. Genes involved in each metabolic process are indicated in italic blue letters surrounded by a rectangle. The details of each metabolic pathway are described by Hirano et al. (2008).
