Pattern identification and characterization reveal permutations of organs as a key genetically controlled property of post-meristematic phyllotaxis.

Abstract excerpt

In vascular plants, the arrangement of organs around the stem generates geometric patterns called phyllotaxis. In the model plant, Arabidopsis thaliana, as in the majority of species, single organs are initiated successively at a divergence angle from the previous organ close to the canonical angle of 137.5°, producing a Fibonacci spiral. Given that little is known about the robustness of these geometric...
