Arabidopsis wild-type (WT) and transgenic plants overexpressing AtCAP1 (S11, S9, and S4) were used. Observations were made 7 days after Dex treatment (1 μM) of 4-day-old {[A](a)} or 7-day-old {[A](b) and [B]} plants. Data are means (±sd) of more than 128 cells per leaf [B].
a Cell number of a single cell layer in a cross-section of the adaxial surface.
b Cell number of the first layer of palisade cells.
