  We investigate defects between supersymmetric Landau-Ginzburg models whose
superpotentials are related by a variable transformation. It turns out that
there is one natural defect, which can then be used to relate boundary
conditions and defects in the different models. In particular this defect can
be used to relate Grassmannian Kazama-Suzuki models and minimal models, and one
can generate rational boundary conditions in the Kazama-Suzuki models from
those in minimal models. The defects that appear here are closely related to
the defects that are used in Khovanov-Rozansky link homology.
