DN-rop3 and rop3 Mutants Have Defective Cell Divisions in the Basal Lineage of the Embryos.

(A) to (E) Wild-type embryos at 16-cell (A), 32-cell (B), globular (C), triangle (D), and heart (E) stages.

(F) to (J) Embryos of RPS5A_pro:DN-rop3 transgenic plants at 16-cell (F), 32-cell (G), globular (H), triangle (I), and heart (J) stages. Arrows indicate the position of aberrant cell division plate.

(K) to (O) rop3 embryos at 16-cell (K), 32-cell (L), globular (M), triangle (N), and heart (O) stages. Bracketed area displays cell division defects in basal embryo region, and the lower one in (G), (K), and (M) shows abnormal cell divisions in suspensor cells.

Bars = 20 μm in (E), (J), and (O) and 10 μm for the rest of the images.
