Hypocotyl growth : Could you do anisotropical growth with isotropic material ?

Siobhan Braybrook, Herman Hoft, Alexis Peaucelle

To escape from the globular shape pluricellular organism have to develop locale tissue polar growth else named as anisotropicale growth. The axially organisation of plants is one of the best example. This ability of plants for astonishing anisotropical growth is associated to the anisotropical properties of the cell walls controlled by cellulose microfibril orientation. Here we want to question this paradigm. We will present a model of anisotropical growth based on cellular mechanic asymmetry. We will present experiments using the young seedling shoot : the hypocotyl to investigate the strength and limits of the model. We believe that our data throw a new light on tissue cell mechanics control of morphogenesis.
