We study junctions consisting of confining strings in N=1 supersymmetric large N gauge theories by means of the gauge/gravity correspondence. We realize them as D-brane configurations in infrared geometries of the Klebanov-Strassler (KS) and the Maldacena-Nunez (MN) solutions. After discussing kinematics associated with the balance of tensions, we compute energies of baryon vertices numerically. In the KS background, baryon vertices give negative contributions to energies. The results for the MN background strongly suggest that energies of baryon vertices exactly vanish just like the case of supersymmetric (p,q)-string junctions. We find that brane configurations in the MN background have a property similar to the holomorphy of the M-theory realization of (p,q)-string junctions. With the help of this property, we analytically prove the disappearance of the energies of baryon vertices in the MN background.
