Modelling wood formation and structure: power and limits of a morphogenetic gradient in controlling xylem cell proliferation and growth

The emergence of the characteristic tree-ring pattern during xylogenesis is commonly thought to be controlled by a gradient of morphogen (auxin, TDIF peptide...). We show that this hypothesis accounts for several developmental aspects of wood formation, but not for the final anatomical structure.
