FIGURE 6.

Overexpression of SchSDD1-like in tomato plants reduces stomatal index and density in cotyledons. (A) DIC micrographs showing representative adaxial epidermal phenotypes in the control (Moneymaker), and three transgenic lines; the stomata have been drawn for clarity. Scale bars: 50 μm (B) Adaxial and abaxial stomatal density in cotyledons and stomatal index for the same lines. Data represent mean ± SE (n = 27). Asterisks indicate significant differences compared to the control (Student’s t-test, ^∗P < 0.05, ^∗∗P < 0.01).
