Hierarchical clustering matrix for correlation between gene expression profiles under different hormone treatments. The indexes are shown on the horizontal axis. The experiments screened by HORMONOMETER are shown on the vertical axis. A, Correlation values between independent hormone treatment experiments and the hormone expression index. Treatments are as follows: ZEA180, ZEA (cytokinin) at 1 μm, 180 min, 7-d-old seedlings; ZEA_ind, ZEA at 20 μm, 21-d-old seedlings; BR180, BRs at 10 nm, 180 min; BR_ind, BRs at 1 μm, 180 min. B, Correlation values between the hormone expression index and MJ180 hormone treatment and shuffled values of the MJ180 hormone treatment (MJ180_shuffled). C, Correlation values between the hormone expression index and the original hormone treatments used to build the indexes. The experiments listed on the vertical axis are clustered together according to the similarity of their profiles (the entire range of correlation values for each experiment). The hormone indexes on the horizontal axis are listed in the same order as the hierarchical clustering to emphasize correlations between cognate and noncognate hormones. The lowercase letters indicate areas as explained in the text.
