While WT leaves progressively flatten, jaw-D leaves curve at the base. Gaussian curvature displayed as heatmaps on wildtype (left) and jaw-D mutant (right) leaf meshes. Gaussian curvature represents both the magnitude and direction of curvature such that values further from zero represent greater curvature. Orange arrows indicate high positive curvature that develops at the base of jaw-D leaves. Black scale bars = 200 µm.
