The main goal of this paper is to show that the (multi-homogeneous) coordinate ring of a partial flag variety C [G/P K−] contains a cluster algebra if G is any semisimple complex algebraic group. We use derivation properties and a special lifting map to prove that the cluster algebra structure A of the coordinate ring C [N K] of a Schubert cell constructed by Goodearl and Yakimov can be lifted, in an explicit way, to a cluster structure A ˆ living in the coordinate ring of the corresponding partial flag variety. Then we use a minimality condition to prove that the cluster algebra A ˆ is equal to C [G/P K−] after localizing some special minors.
