We use general relations between the Transition Distribution Amplitudes (TDAs), entering the description of the p {yields} {pi}0 transition, and the proton Distribution Amplitudes (DAs) in the soft-pion limit to estimate the size of the amplitude for backward electroproduction of {pi}0 at large Q2.
