Fig. 1. jba-1D morphological phenotypes are dose dependent. (A) Wild-type
Columbia (Col) inflorescence stem. (B) Fasciated jba-1D/+ stem. (C)
Severely fasciated jba-1D stem. (D) SEM of a wild-type inflorescence
meristem. Inset: an enlargement of the shoot tip (the boxed region). (E) SEM
of a fasciated jba-1D inflorescence meristem. (F) Wild-type silique
consisting of two fused carpels. (G) Reduced and filamentous jba-1D/+
siliques. (H) Filamentous jba-1D silique. (I) Radialized leaf
projecting outward from the center of a jba-1D inflorescence
meristem. (J) Wild-type rosette leaf, viewed from the abaxial side. (K)
Slightly downward curled jba-1D/+ rosette leaf. (L) Severely downward
curled jba-1D rosette leaf. (M) Completely radialized rosette leaf
from a jba-1D seedling. Scale bars: 60 µm (D,E).
