Figure 5.

Spatial profile of cortical cell deposition rate versus distance from the quiescent center on d 8 for Arabidopsis wild type, stp1, and wild type treated with 1.0 μm zeatin or 30 nm 2,4-D. Cell deposition rates were calculated for each root from Equation 1 and averaged. The local time-dependent change in cell density was zero for stp1 and zeatin-treated roots. Symbols are means ± se, as given for Figure 2.
