Morphology of the Wild Type and the fra2 Mutant.

(A) Morphology of 8-week-old plants. The main inflorescence stem of a fra2 plant (right) is much shorter than that of a wild-type plant (left).

(B) and (C) The main inflorescence stems. The fra2 stem (C) has reduced internode length compared with the wild-type stem (B).

(D) and (E) Siliques of wild type (D) and fra2 (E).

(F) and (H) The rosette leaves of a 5-week-old fra2 plant (H) are more compact than those of a wild-type plant (F).

(G) and (I) Individual leaves of 5-week-old plants. The lengths of both blades and petioles in fra2 (I) are reduced compared with those of the wild type (G). From left to right, the leaves are arranged according to the order from cotyledons to the youngest leaves.
