Figure 2.

OSH1 and OSH15 Are Redundantly Required for SAM Formation.

(A) to (C) Sections of wild-type (wt) embryos at 4 DAP (A), 5 DAP (B), and 10 DAP (C). Black arrowheads indicate the position of the SAM.

(D) to (F) Sections of osh1 d6 double mutant embryos at 4 DAP (D), 5 DAP (E), and 10 DAP (F). White arrowheads indicate the position where SAM formation should be observed in the wild type.

(G) An osh1 d6 double mutant at 10 DAG (cf. to Figure 1D).

(H) Top view of (G).

Bars = 100 μm in (A) to (F) and 5 mm in (G) and (H).
