GENETIC IMPROVEMENT METHOD CAPABLE OF SPECIFICALLY ENHANCING SEED DORMANCY AND APPLICATION THEREOF

摘要

Provided is a plant improvement method, wherein knocking out N members (N ≥ 1) of a miR156 gene family can improve seed dormancy and enhance the capability of pre-harvest sprouting prevention of seeds. Also provided are a genetically engineered plant tissue or plant cell and a preparation method therefor, a method for preparing a genetically engineered plant, a grain production method, and use of a miR156 gene family inhibitor.
