We prove that a minimal subshift in the Jeandel-Rao aperiodic Wang shift is isomorphic as measure-preserving dynamical system to a Z2-rotation on the torus T2. The proof is based on the substitutive structure of Jeandel-Rao aperiodic tilings described in some earlier work and on a renormalization scheme defined on partitions of the torus T2 and Z2-actions. As a consequence, this provides a construction of Jeandel-Rao aperiodic Wang tilings as model sets of cut and project schemes.
