Fig. 3. WUS expression domain is elongated for flatter meristems.

Fig. 3

(A) Meristem and expression domain shapes. The x axis is the value of the a parameter of the parabola outlying the meristem; the higher the value, the flatter the meristem (see the Supplementary Materials). The y axis is the ratio between the longest vertical axis of pWUS >> GFP expression domain and its longest horizontal axis; the higher the value, the more horizontally elongated the domain is. (B) Recorded meristem shapes plotted as parabolas. The horizontal span of a plain parabola corresponds to the width of the treated image. (C) Modeled meristem and expression domain shapes. The x axis shows the different tissue templates displayed in fig. S12. For the parameter sets optimized for the 2D template, the y axis shows WUS expression domain elongation (longest vertical axis over longest horizontal axis). (D) Examples of processed images. The automatically defined parabolas and expression domains axes are plotted in blue. Scale bar, 20 μm.
