A systematic microscopic theory of magnetically induced ferroelectricity and lattice modulation is presented for various electron configurations of Mott-insulating transition metal oxides. The origin of polarization is classified as the spin-orbit interaction effective (i) within the magnetic ${t}_{2g}$ orbitals, (ii) between the ${t}_{2g}$ and ${e}_{g}$ orbitals, and (iii) within the ligand ion's $p$ orbitals. Predictions for x-ray and neutron scattering experiments are proposed to clarify the microscopic mechanism of the spin-polarization coupling in different materials. Semiquantitative agreements with the multiferroic $\mathrm{Tb}\mathrm{Mn}{\mathrm{O}}_{3}$ are obtained.
