摘要
A method for creating a new germplasm of a male sterile crop by gene editing and an application thereof are provided. In this method, the gene editing is performed on an exon region of a Ty-5 gene, and a deletion of DNA sequence is introduced by using a repair mechanism of plants themselves to double-strand breaks (DSBs), causing a loss of function of Ty-5 gene, thereby obtaining a male-sterile character. The method can be applied without being limited by crop categories. After the gene editing is performed on Ty-5 genes of various crops, new germplasms can be quickly obtained. The new germplasms have the same agronomic characters as the previous materials, and only differ in sexual aspect, which effectively solves the problem of the lack of male sterile materials and unstable fertility in natural resources.
