Abstract We calculate various tree-level (disk) scattering amplitudes involving gauge, matter and moduli fields in IIB toroidal orbifold/orientifold backgrounds with D9-, D5- respectively D7-, D3-branes or via T -duality D6-branes in type IIA compactifications. In type IIB the D-branes may have non-vanishing fluxes on their world-volume. From these results we extract the moduli and flux dependence of the tree-level gauge couplings, the metrics for the moduli and matter fields. The non-vanishing fluxes correspond in the T -dual type IIA description to intersecting D6-branes. This allows us to determine the moduli dependence of the tree-level matter field metrics in the effective action of intersecting D6-brane models. In addition we derive the physical Yukawa couplings with their correct normalization.
