We consider the Kawai-Lewellen-Tye (KLT) factorizations of gravity scalar-leg amplitudes into products of Yang-Mills scalar-leg amplitudes. We check and examine the factorizations at O(1) in {alpha}{sup '} and extend the analysis by considering KLT mapping in the case of generic effective Lagrangians for Yang-Mills theory and gravity.
