Gravity amplitudes are via the Kawai-Lewellen-Tye relations intimately linked to products of Yang-Mills amplitudes. Explicitly this show up in computations of N=8 supergravity where the perturbative expansion and ultraviolet behaviour of this theory is akin to N=4 super-Yang-Mills at least through three loops. Full persistency to all loop orders would be truly remarkable and imply finiteness of N=8 supergravity in four dimensions.
