In supersymmetric theories with extra dimensions, the Higgs and matter fields can be part of the gauge multiplet, so that the Yukawa interactions can arise from the gauge interactions. This leads to the possibility of gauge-Yukawa coupling unification, gi=yf, in the effective four-dimensional theory after the initial gauge symmetry and the supersymmetry are broken upon orbifold compactification. We consider gauge-Yukawa unified models based on a variety of four-dimensional symmetries, including SO(10), SU(5), Pati-Salam symmetry, trinification, and the standard model. Only in the case of Pati-Salam and the standard model symmetry, we obtain gauge-Yukawa unification. Partial gauge-Yukawa unification is also briefly discussed.
