We consider Yang-Mills theories formulated on a noncommutative space-time described by a space-time dependent antisymmetric field thetaµnu(x). Using Seiberg-Witten map techniques, we derive the leading order operators for the effective field theories that take into account the effects of such a background field. These effective theories are valid for a weakly noncommutative space-time. It is remarkable to note that already simple models for thetaµnu(x) can help to loosen the bounds on space-time noncommutativity coming from low energy physics. Noncommutative geometry formulated in our framework is a potential candidate for new physics beyond the standard model.
