摘要:
The invention relates to a plant genetic engineering field, and more particularly to a method for creating directed gene mutated non-transgenic plants. The method including performing a transgenic method onto directed gene mutated plants by introducing exogenous nucleic acid molecules; wherein the transgenic method includes introducing constructs into the directed gene mutated plants, each of the constructs contains a first nucleic acid molecule and a second nucleic acid molecule, wherein the first nucleic acid molecule serves as a gene editing element, and the second nucleic acid molecule serves as a lethal or stop development element, and can be used in a plant gene editing system such as CRISPR/CAS9. It can actively and automatically eliminate plant transgenic fragments, leaving enough time for gene editing elements to perform directed gene editing before removing transgenic fragments, providing a simple and effective method for gene editing without transgenic plants.
