Modeling a Trichome Turing Pattern on the leaf of Arabidopsis Thaliana
Trichomes are hairs consisting of a single cell which can be seen developing on the surface of leaves of Arabidopsis Thaliana. Their specialization from regular epithelial cells is determined by a pattern which can be described by coupling the intracellular reactions of multiple cells to each other. We assume that cells are immobile but exchange the ’trichome-promoting factor TRANSPARENT TESTA GLABRA1’ (TTGL) [@Bouyer2008] via their connecting cell wall.
We descibe the intracellular gene reulatory network as an Ordinary
Differntial Equation (ODE) via the Intracellular simulation aspect and couple cells to each other
with the ReactionsContact aspect.
We restrict the reactions via contact to only neighbouring cells exchange TTGL which is particularly
simple to determine for a static tissue.
The combined reactions represent a diffusion-driven Turing instability [@Turing1952] which when
given randomized initial values generates peaks that lead to the observed differentiation of the
trichome hairs.
