Figure 3. Effects of sucrose exposure on stomatal lineage cell markers.

Figure 3

(A and B) Mature guard cell marker E1728-labeled [15] and FM4-64-stained cotyledon epidermis from sugar-free control (A) and 1% sucrose (B) treatments. (C and D) Stomatal cell lineage marker E1627-labeled [15] and FM4-64-stained cotyledon epidermis from sugar-free control (C) and 3% sucrose (D) treatments. Representative images from 10–15 independent seedlings were shown. Note that the jigsaw puzzle-shaped epidermal cells were labeled with E1627 in the sucrose treatment but not in the sugar-free control. Scale bars  = 20 μm.
