We consider the f(R,T) theory, where R is the scalar curvature and T is the trace of energy-momentum tensor, as an effective description for the holographic and new agegraphic dark energy and reconstruct the corresponding f(R,T) functions. In this study, we concentrate on two particular models of f(R,T) gravity namely, R+2A(T) and B(R)+\lambda T. We conclude that the derived f(R,T) models can represent phantom or quintessence regimes of the universe which are compatible with the current observational data. In addition, the conditions to preserve the generalized second law of thermodynamics are established.
