Table I. Orientation of PPBs and phragmoplasts in Ler (tan1/+; air9/+), tan1, air9, and the tan1 air9 double mutant expressing CFP-TUBULIN (CT) to assess microtubule structure orientation

The numbers in parentheses correspond to independent transformation events. Normal orientation is defined as division structure angles between 80° and 100°, while aberrant orientation is defined as angles outside this range. These data are plotted in Figure 2A.
