Expression of auxin-inducible genes in dark-grown plant lines in response to auxin treatments. The transcript levels of early auxin-responsive genes and auxin efflux carrier genes in WT, KO and OE1 were detected after treatment with 1 μM auxin for 12 h in the dark. The data were normalized based on the transcript levels of the genes in the corresponding non-treated samples. The data are from three biological treatments. Values are means ± SD (n = 3 technical replicates). *, ** and *** indicate significant differences at P ≤0.05, P ≤0.01 and P ≤0.001, respectively, by Student’s t test.
