Anticlinal and Periclinal Wall Growth Varies across a Region of Contiguous Pavement Cells.

Fluorescently stained pavement cells at the base of a cotyledon and their digital outlines on days 1, 2, and 3 after germination. The relative anticlinal and periclinal wall growth rates from days 1 to 2 are depicted as a color scale on day 2 images and the growth rates from days 2 to 3 on day 3 images. New anticlinal walls are gray because their growth rates could not be calculated. New lobes sometimes developed within preexisting lobes (black arrowhead). Each thin-plate spline (mesh overlay on the periclinal wall images) models differential movement of the wall junctions (black dots) between days. Bar = 100 µm.
