Query: E3-brane instantons and baryonic operators for D3-branes on toric
  singularities   We consider the couplings induced on the world-volume field theory of
D3-branes at local toric Calabi-Yau singularities by euclidean D3-brane
(E3-brane) instantons wrapped on (non-compact) holomorphic 4-cycles. These
instantons produce insertions of BPS baryonic or mesonic operators of the
four-dimensional ${\cal{N}}=1$ quiver gauge theory. We argue that these systems
underlie, via the near-horizon limit, the familiar AdS/CFT map between BPS
operators and D3-branes wrapped on supersymmetric 3-cycles on the 5d horizon.
The relation implies that there must exist E3-brane instantons with appropriate
fermion mode spectrum and couplings, such that their non-perturbative effects
on the D3-branes induce operators forming a generating set for all BPS
operators of the quiver CFT. We provide a constructive argument for this
correspondence, thus supporting the picture.
