Reaction-Diffusion Pattern in Shoot Apical Meristem of Plants
Abstract
This paper addresses the fundamental question of how spatial patterns self-organize from homogeneous structures, building on Turing's 1952 reaction-diffusion model. The authors demonstrate that a reaction-diffusion model can successfully explain shoot apical meristem (SAM) development in plants by developing a mathematical model based on reaction-diffusion dynamics of the WUS-CLV interaction.

- How can chemicals that react and spread create a pattern?
- How do cells know where they are in a growing body?
- How does a living thing know what shape to grow into?
- How does auxin shape a growing plant?
- How can a reaction-diffusion model, building on Turing's 1952 framework, explain the spontaneous emergence of spatial pattern from an initially homogeneous meristem?
- How does the WUS-CLV feedback system generate the overlapping molecular gradients that define distinct zones within the shoot apical meristem?
- What mechanism allows the shoot apical meristem to maintain a stable size over time despite developmental perturbations?
- Why do the authors argue that reaction-diffusion dynamics are indispensable, rather than merely one possible explanation, for shoot apical meristem development?
