On AdS/CFT as open/closed string duality and early discussion of the concept of probe branes in AdS/CFT:

Introducing the concept of flavor branes for geometric engineering of flavour physics in intersecting D-brane models (AdS/QCD):

On Seiberg duality for gauge groups which are exceptional Lie groups:

Andreas Karch writes here:

These anomalous transport coefficients have first been calculated in AdS/CFT. The relevant references are [8], [9] and [10] in the Son/Surowka paper. In the AdS/CFT calculations these particular transport coefficients only arise due to Chern-Simons terms, which are the bulk manifestation of the field theory anomalies. At that point it was obvious to many of us that there should be a purely field theory based calculation, only using anomalies, that can derive these terms. Son and Surowka knew about this. They were sitting next door to me when they started these calculations. Many of us tried to find these purely field theory based arguments and failed. Son and Surowka succeeded.
