Endogenous CK levels are required for local auxin maxima formation and mediate PIN gene expression in Arabidopsis roots. (A) Depletion of endogenous CKs in Pro35S:AtCKX2 and Pro35S:AtCKX3 lines leads to the defects in auxin response gradients as visualized by DR5rev:GFP. Note the lateral expansion of the maxima in transgenic lines (arrowheads) in comparison to WT. (Scale bar: 10 μm.) (B) Relative PIN transcription measured by qRT-PCR in Pro35S:AtCKX2 and Pro35S:AtCKX3 roots in comparison to WT. The statistical significance of differences (t test) at alpha 0.01 is marked by **; error bars show SDs.
