PP2A-3 mediates columella stem cell divisions. (A and B) Representative images (A) and quantification (B) of columella stem cell daughter cell differentiation (20 ≤ n ≥ 96) and irregular cellular pattern in pp2a-3 pp2a-4 (A, Right). Statistical significance (Z Test Calculator for 2 Population Proportions, P < 0.05) compared with Col-0 (*) or acr4 (#) is indicated. (C and D) Expression of QC184 and pWOX5::GUS in 5-d-old pp2a-3 pp2a-4 seedlings (C) or in 5-d-old seedlings grown on 10 µM cantharidin (D). Representative pictures with number of seedlings with similar expression pattern indicated. Pink arrowhead, quiescent center. Yellow asterisk, first columella cell layer with starch granules.
