  It is known that the fermionic shift symmetry of the N=1, U(N) gauge model
with a superpotential of an adjoint chiral superfield is replaced by the second
(spontaneously broken) supersymmetry in the N=2, U(N) gauge model with a
prepotential and Fayet-Iliopoulos parameters. Based on a diagrammatic analysis,
we demonstrate how the well-known form of the effective superpotential in the
former model is modified in the latter. A set of two equations on the one-point
functions stating the Konishi anomaly is modified accordingly.
