Table II. Orientation of PPBs and phragmoplasts in tan1air9 mutants expressing TAN1-YFP, TAN1-ΔRI-YFP, and TAN1-ΔRII-YFP or the nontransformed siblings with CFP-TUBULIN (CT)

The numbers in parentheses refer to the transformation event number. Normal orientation is defined as angles between 80° and 100°, and aberrant orientation corresponds to angles outside this range. These data are plotted in Figure 4, J and K.
