The interaction mechanism of the Sigma(1385) photoproduction from proton gamma p -> K+Sigma(0)(1385) is investigated within a Regge-plus-resonance approach based on the experimental data released by the CLAS Collaboration recently. The t channel and the u channel are responsible for the behaviors of differential cross sections at forward and backward angles, respectively. The contributions from nucleon resonances including N-* and Delta(*), which are determined by the predicted decay amplitudes in the constituent quark model, are found to be small, but the F-35 state Delta(2000) is essential to reproduce the differential cross section.
