##### Abstract

In this short note, we prove the supersymmetric Kawai-Lewellen-Tye (KLT)
relations between N=8 supergravity (SUGRA) and N=4 super Yang-Mills (SYM)
tree-level amplitudes in the frame of S-matrix program, especially we do not
use string theory or the explicit Lagrangian form of corresponding theories.
Our supersymmetric KLT relations naturally unify the non-supersymmetric KLT
relations and newly discovered gauge theory identities and produce more
identities for amplitudes involving scalars and fermions. We point out also
that these newly discovered identities can be used to reduce helicity basis
from (n-3)! further down.
