Phyllotaxis, the regular arrangement of leaves or flowers around a plant stem, is an example of developmental pattern formation and organogenesis. Phyllotaxis is characterized by the divergence angles between the organs, the most common angle being 137.5°, the golden angle.

What causes Phyllotaxis?

The phyllotactic pattern therefore results from a dynamic interaction between existing and newly initiating organ primordia on the flanks of the SAM, mediated by actively transported auxin, such that new primordia emerge at sites of high auxin concentration and maintain a minimum distance from each other by depleting ...

What is meant by Phyllotaxis?

1 : the arrangement of leaves on a stem and in relation to one another.
