Abstract: Exclusive $\pi^0$ electroproduction from nucleons at large $Q^2$ can bedescribed by Generalized Parton Distributions GPDs, particularly the chiralodd subset related to transversity. These GPDs can be accessed experimentallyfrom various cross sections and asymmetries. We calculate these GPDs in aspectator model, constrained by boundary functions. Alternatively, in ahadronic picture the meson production amplitudes correspond to C-odd Reggeexchanges with final state interactions. The helicity structure providesrelations between the partonic and the hadronic, Regge description of C-odd,chiral-odd processes. Calculations show how the tensor charge and othertransversity parameters can be
