Phenotypic Characterization of the bard1-3 Arabidopsis Mutant.

Wild-type Columbia (Col-0) plants are shown in the top two rows, and bard1-3 plants are shown in the bottom two rows. (A), (E), (I), and (M) were photographed at the same growth period with panels (C), (G), (K), and (O), respectively. White bars = 1 mm; black bars = 50 μm.

(A) to (D) Seedlings 5 DAG.

(E) to (H) One-week-old seedlings.

(I) to (L) Three-week-old plants.

(M) and (O) Five-week-old plants.

(A), (E), (I), and (M) Photographs of wild-type Col-0 plants.

(C), (G), (K), and (O) Photographs of the bard1-3 mutant.

(B), (F), and (J) Median longitudinal semithin sections stained with toluidine blue showing wild-type SAMs at corresponding growth stages.

(D), (H), and (I) Sections of bard1-3 mutant SAMs at growth stages described above.

(N) Cross section of a mature wild-type leaf.

(P) Cross section of the leaf-like structures from the 5-week-old bard1-3 mutant.
