Certain scattering amplitudes in N=4 D=4 super Yang-Mills theory and neighbouring gauge theories – called *maximally helicity violating amplitudes* (“MHV amplitudes”) simplify drastically as compared to the generic situation and in fact are controled by a certain twistor string theory whose target space is a twistor space. See (Monteiro) for a review.
