fil-9 versus wild type inflorescence meristems and floral primordia. (A to C) Top view of early wild type (A) and fil-9 (B, C) inflorescences. The scale bar represents 100 μm. (D and E) A schematic representation of floral orientation relative to the IM in wild type and fil-9 plants, respectively. IM, inflorescence mersitem; Se, sepal. (F to H) Enlarged view of early wild type (F) and fil-9 (G, H) inflorescences. Floral primordia are labeled 0, 1, 2, etc., in order of increasing age. The scale bar represents 20 μM. (I to K) Enlarged view of late wild type (I) and fil-9 (J, K) inflorescences. The scale bar represents 20 μm. IM, inflorescence mersitem. (L to N) Top view of early wild type (L) and fil-9 (M and enlarged view in N) inflorescences, labeled with FM4-64 (red) PIN1-GFP (green). The scale bar represents 20 μm. The yellow circle designates the area used for cell number count. The average number of cells in the defined meristematic area did not differ between fil-9 and wild type plants (ANOVA, F1,38 = 0.326, P = 0.571).
