Abstract: The present disclosure provides a method for increasing a methionine content in grains by gene knockout. A maize ZmMETS2 gene is knocked out by a CRISPR/Cas9 technology, and it is found that the methionine content in maize grains is increased to a certain extent after the gene is knocked out. In the present disclosure, the CRISPR/Cas9 target site of the maize ZmMETS2 gene is designed and a function of the gene is found to significantly affect the methionine content. This provides a reference for CRISPR researches of the gene in maize and other crops, and provides a theoretical basis for methionine metabolism of the maize and other crops. Accordingly, the deficiency of human amino acid nutrition is alleviated by increasing the methionine content of transgenic plants.
