ICMT Overexpression Lines of Arabidopsis Exhibit Reduced ABA Inhibition of Seed Germination Compared with Control Col-0 Plants.

Seed germination was scored for Col-0, ICMT^ox1, and ICMT^ox2 lines as a function of time in the presence of 0, 0.5, 2.5, or 5.0 μM cis-ABA (each data point represents three independent trials; 40 < n < 83). The se is indicated for all data points. Asterisks represent significant differences from the Col-0 control of * P < 0.05, ** P < 0.01, and *** P < 0.001, as determined by Student's t test.
