Fig. 1.

FHY3 is required for FM determinacy and SAM maintenance. (A–C, E, and F) Siliques of Ler (A), ag-10 (B), fhy3-68 ag-10 (C), 35S:FHY3-FLAG fhy3-68 ag-10 (E), and fhy3-68 (F). Carpels marked by red arrows in F. (D) Flowers of fhy3-68 ag-10. Sterile anthers are marked by a white arrow in D. (G) Quantification of inflorescence size (mm) of Ler (n = 15) and fhy3-68 (n = 15). **P < 0.01. (H and I) Inflorescences of Ler (H) and fhy3-68 (I). Dashed lines mark the width used to measure inflorescence size in G. (J and K) SAM (marked by a red arrow) of Ler (J) and fhy3-68 (K). Red lines mark the width of SAM. (Scale bars: 1 mm in A–C, E, and F; 250 µm in D; 500 µm in H and I; 60 µm in J and K.)
