Cell size patterning in Arabidopsis flowers.

A confocal projection of the cluster of flowers surrounding the growing tip of Arabidopsis shows the formation of cells with a large range of sizes on the sepals of the developing flowers. The variable decisions of cells on the outer surface of the sepals, concerning division time and when to stop dividing, create this characteristic pattern (see Roeder et al., e1000367). Cell nuclei and plasma membranes are shown in green; chloroplasts are in red for contrast. The pattern develops progressively from the youngest flowers near the center to the older flowers on the periphery.
