Coincident D3-branes placed at a conical singularity are related to string theory on (Formula presented) for a suitable five-dimensional Einstein manifold (Formula presented) For the example of the conifold, which leads to (Formula presented) the infrared limit of the theory on N D3-branes was constructed recently. This is an N=1 supersymmetric (Formula presented) gauge theory coupled to four bifundamental chiral superfields and supplemented by a quartic superpotential which becomes marginal in the infrared. In this paper we consider D3-branes wrapped over the 3-cycles of (Formula presented) and identify them with baryon-like chiral operators built out of products of N chiral superfields. The supergravity calculation of the dimensions of such operators agrees with field theory. We also study the D5-brane wrapped over a 2-cycle of (Formula presented) which acts as a domain wall in (Formula presented) We argue that upon crossing it the gauge group changes to (Formula presented) This suggests a construction of supergravity duals of N=1 supersymmetric (Formula presented) gauge theories.
