Time Sequence of Stomatal Differentiation in scrm-D.

Images of the abaxial epidermis of wild-type and scrm-D cotyledons. TMM:GUS-GFP (green) was used to monitor stomatal lineage cells. Arrowheads, GFP positive cells underwent cell division; asterisks, meristemoids; +, mature stomata. Images were taken under the same magnification. Bar = 50 μm.

(A) Wild-type cotyledon at 1 d after germination (dag).

(B) scrm-D cotyledon at 1 d after germination.

(C) Wild-type cotyledon at 3 d after germination.

(D) scrm-D cotyledon at 3 d after germination.

(E) Wild-type cotyledon at 4 d after germination.

(F) scrm-D cotyledon at 4 d after germination.

(G) Wild-type cotyledon at 5 d after germination.

(H) scrm-D cotyledon at 5 d after germination.
