  We study gravity duals of large N non-supersymmetric gauge theories with
matter in the fundamental representation by introducing a D7-brane probe into
deformed AdS backgrounds. In particular, we consider a D7-brane probe in both
the AdS Schwarzschild black hole solution and in the background found by
Constable and Myers, which involves a non-constant dilaton and S^5 radius. Both
these backgrounds exhibit confinement of fundamental matter and a discrete
glueball and meson spectrum. We numerically compute the quark condensate and
meson spectrum associated with these backgrounds. In the AdS-black hole
background, a quark-bilinear condensate develops only at non-zero quark mass.
We speculate on the existence of a third order phase transition at a critical
quark mass where the D7 embedding undergoes a geometric transition. In the
Constable-Myers background, we find a chiral symmetry breaking condensate as
well as the associated Goldstone boson in the limit of small quark mass. The
existence of the condensate ensures that the D7-brane never reaches the naked
singularity at the origin of the deformed AdS space.
