(A) 4EnhP_YABBY3-IAMT1 construct. LB, polyA, Kan^R, 35S-P, 4Ehancer, IAMT1, Ter, and RB are as in Figure 1. YABBY3-P, promoter of the YABBY3 gene.

(B) Thirty-two-day-old wild-type Arabidopsis plant (top) with a transverse leaf section (bottom).

(C) Thirty-two-day-old 4EnhP_YABBY3-IAMT1 transgenic plant (top) with a transverse leaf section (bottom).

(D) A wild-type Arabidopsis flower.

(E) A flower from a 4EnhP_YABBY3-IAMT1 transgenic plant.

(F) Comparison of siliques from wild-type and 4EnhP_YABBY3-IAMT1 transgenic plants.
