  We consider supersymmetric Wilson loops a la Zarembo in planar supersymmetric
Yang-Mills theories in diverse dimensions. Using perturbation theory we show
that these loops have trivial vacuum expectation values to second order in the
't Hooft coupling. We review the known superspace results which, for specific
dimensions, extend this triviality to all orders in the 't Hooft coupling.
Using the gauge/gravity correspondence, we construct the explicit dual
fundamental string solutions corresponding to these Wilson loops for the case
of circular geometry. We find that the regularized action of these string
solutions vanishes. We also generalize the framework of calibrated surfaces to
prove the vanishing of the regularized action for loops of general geometry. We
propose a possible string-side manifestation of the gauge theory generalized
Konishi anomaly in seven dimensions.
