Supergravity with Fayet-Iliopoulos terms and R-symmetry
  The simplest examples of gauged supergravities are N=1 or N=2 theories with Fayet-Iliopoulos (FI) terms. FI terms in supergravity imply that the R-symmetry is gauged. Also the U(1) or SU(2) local symmetries of Kaehler and quaternionic-Kaehler manifolds contribute to R-symmetry gauge fields. This short review clarifies the relations.
