Phenotypic Analysis of Arabidopsis sme1 Mutants.

(A) to (H) Morphological phenotypes of wild-type (WT), sme1-1, and sme1-2 plants. Three-day-old seedlings (A), cotyledon vein patterns (B), 7-week-old plants (C), rosette leaves of 4-week-old plants (D), trichomes on the leaves of 4-week-old plants (scale bars indicate 0.25 mm) (E), 14-d-old seedlings (F), flowers (G), and 4-week-old plants (H).

(I) Total number of leaves, after appearance of the floral bud (blue bars) or the first flower (red bars), in wild-type, sme1-1, and sme1-2 plants grown under control conditions. Data represent the mean of six independent experiments. Asterisks indicate significant differences (***P < 0.0001) between sme1 mutants and wild-type plants, as determined by one-way ANOVA (Dunnett’s post-hoc test). Error bars indicate the SD.
