Target- ed approach based on the principle of “Substantial Equivalence”focusing on the qualitative and quantitative analysis of key elements between GM crop and its counterpart hardly cover the occurrence of unpredictable changes. The functional genomics, proteomics and metabolomics are evolved to detect unintended effects, which might in future complement present widely be used as targeted ap- proach. The three “omics”techniques are potentially powerful, but much work has still to be done. In this review, the techniques are described, together with their current applications and limitations, introducing recent study progresses in the aspect of the detection of unintended
