AB - We provide a formulation of generalized vector dominance (GVD) for low-x deep-inelastic scattering that explicitly incorporates the gamma* --> q (q) over bar transition and a QCD-inspired ansatz for the (q (q) over bar)p forward-scattering amplitude. The destructive interference originally introduced in off-diagonal GVD is recovered in the present formulation and traced back to the generic structure of two-gluon-exchange as incorporated into the notion of colour transparency. Asymptotically, the transverse photoabsorption cross section behaves as (In Q(2))/Q(2), implying a logarithmic violation of scaling for F-2, while the longitudinal-to-transverse ratio decreases as 1/lnQ(2).
