Figure 5.

Cell lineage analyses reveal multiple cell division events leading to increases in radial anticlinal cortical cell file number. Unrolled images showing cell lineages in the cortex of Arabidopsis roots under high Pi (Left) and low Pi (Right). Using Adobe After Effects we digitally dissected the membranes between cortex cells. In ImageJ. We unrolled this data set in order to visualize the cortical cell lineages within the root meristem. The dissected cell layers unrolled are shown in Supplemental Movie 2. Whilst 8 continuous cell files can be traced from just above the quiescent center until the start of the elongation zone for plants grown on high Pi, when grown on low Pi, we observe multiple events in which CCFN is increased in relatively small numbers of cells. These events are marked with asterisks. Scale bars = 50 μm.
