The Phenotype of RNAi Seedlings Expressing an RNA Directed against the Last BRCT Domain Coding Region of BARD1 Is Similar to that of bard1-3 Mutants.

(A) Close-up photo of a 14-d-old RNAi Arabidopsis seedling.

(B) Semithin longitudinal section of an RNAi seedling that was harvested at the same growth stage as in (A). Note that the SAM structure is similar to that of bard1-3 mutants.

(C) Close-up photo of a 21-d-old RNAi Arabidopsis seedling.

(D) Cross section of a tubular leaf-like structure observed from (C) (denoted by a white arrow) indicating the complete loss of leaf dorsoventrality.

White bars = 1 mm; black bars = 50 μm.
