Heat map view of expression of genes involved in hormone metabolism in the gibberellin signaling mutants, gid1-3, gid2-1 and slr1, and the wild-type ‘Taichung 65’. Hormone metabolism genes with reliable expression data in at least ‘Taichung 65’ were selected from Supplementary Table S4. The relative expression level of each gene compared with expression in ‘Taichung 65’ is shown on the heat map. Red and blue colors indicate higher and lower expression, respectively. The color scale is shown at the bottom. Gray indicates expression data of lower reliability. One of the multiple Affymetrix probes for one gene is marked with an asterisk. T65, ‘Taichung 65’. Abbreviations of genes are shown in the legend to Fig. 4 and the main text.
