In this paper, we discuss various possible schemes for the perturbative generation of the axion-photon interaction term in different Lorentz-breaking extensions of QED, involving operators with mass dimensions up to five. We demonstrate explicitly that there are only a few schemes allowing one to generate a finite axion-photon interaction term from one-loop radiative corrections, and within all these schemes, the generated term turns out to be ambiguous. Also, through the current experimental limits on the axion-photon coupling, we extract some present constraints on the Lorentz violation parameters.
