  We consider a five dimensional AdS warped spacetime in presence of a massive
scalar field in the bulk. The scalar field potential fulfills the requirement
of modulus stabilization even when the effect of backreaction of the
stabilizing field is taken into account. In such a scenario, we explore the
role of backreaction on the localization of bulk fermions which in turn
determines the effective radion-fermion coupling on the brane. Our result
reveals that both the chiral modes of the zeroth Kaluza-Klein (KK) fermions get
localized near TeV brane as the backreaction of the scalar field increases. We
also show that the profile of massive KK fermions shifts towards the Planck
brane with increasing backreaction parameter.
