Auxin and ethylene responsiveness of PAP1 and TTG1 in roots requires TIR1, EIN2, and MYB12. A, The basal level and fold induction of MYB12, PAP1, and TTG1 transcript abundance 6 h after treatment with IAA and ACC is shown in all genotypes. TIR1 and EIN2 are necessary for auxin- and ethylene-dependent gene expression changes, respectively. All data are normalized to untreated wild-type (WT) expression levels. B, Mutations in MYB12 prevent the induction of PAP1 and TTG1 transcript changes after IAA and ACC treatment. Mean and se of three biological replicates are shown. * Significant difference (P < 0.05) between the mutant and the wild type within a treatment; # significant difference between treated and untreated controls within a genotype as determined by Student’s t test (P < 0.05).
