Fig. 2. Effect of the clasp mutation on shoot development. (A) Flowering wild-type plant. (B) Flowering clasp plant of the same age as that in A. (C) Comparison of wild-type (left) and clasp mutant (right) 5-day-old seedlings. Note the shortened hypocotyl and root in the mutant. (D) Scanning electron micrograph (SEM) of hypocotyl epidermis of a 5-day-old wild-type seedling. (E) SEM of a comparable clasp hypocotyl epidermis. Note the shortened and bulged epidermal cells. (F) Rosette of a wild-type plant. (G) Rosette of a clasp plant the same age as in F. Scale bar: 100 µm for D and E.
