Fig. 1. — Provascular activity of the Dof5.8 promoter and its enhancement by auxin. (A) Time course analysis of GUS expression under the control of the Dof5.8 promoter (Dof5.8pro) or the DR5 element (DR5) during development of the primordia of the first true leaves. Two primordia flanking the shoot apical meristem (1 d and 2 d) and individual leaf primordia (2.5–5 d) are shown. Scale bars=20 μm in 1 d and 2 d, 50 μm in 2.5 d and 3 d, 100 μm in 4 d and 5 d. (B) Effect of auxin treatment on the activity of the Dof5.8 promoter. Seedlings were treated or not with 10 μM 2,4-D for 16h. Scale bar=100 μm.
