SUMMARY Advancements in ‐omics techniques provide powerful tools to assess the potential effects composition of a plant at RNA, protein and metabolite levels. These technologies can thus be deployed whether genetic engineering (GE) causes changes plants that go beyond introduced by conventional breeding. Here, we compare extent transcriptome metabolome modification occurring leaves four GE rice lines expressing Bacillus thuringiensis genes developed seven cross‐breeding. The results showed both types crop breeding methods bring transcriptomic metabolic levels, but differences were comparable between two methods, less than those non‐GE were. Metabolome profiling analysis found several new metabolites when compared with closest parental lines, these compounds also conventionally bred lines. Functional analyses suggest differentially expressed caused cross‐breeding do not involve detrimental pathways. study successfully employed RNA‐sequencing high‐performance liquid chromatography mass spectrometry technology unintended varieties, does cause rice.
