Figure 1. Kinematic features of cell proliferation and expansion of wild-type and gif mutant leaves. Adaxial palisade cells of the first 2 leaves were analyzed over the indicated time-lapses after germination on soil. (A) Leaf blade area. (B) Numbers of cells in a line along the maximum-width region. (C) Relative cell proliferation rate. (D) Cell areas. Insets: magnified versions to show differences in the early stages of leaf growth. Note that the inset of (A) was plotted on the natural log scale. n = 10 for determination of organ-level parameters; n = 200 from 10 different organs for cellular parameters. Results are means ± SE.
