Summary: We compute one-loop threshold corrections to \({\mathcal R}^4\) terms in \({\mathcal N}=5.6\) supergravity vacua of Type II superstrings. We then discuss nonperturbative corrections generated by asymmetric D-brane instantons. Finally we derive generating functions for MHV amplitudes at tree level in \({\mathcal N}=5.6\) supergravities.
