PURPOSE: A method for controlling the shape of plant roots is provided to control the shape by regulating OsIDD10 gene expression in a plant. CONSTITUTION: A method for controlling the shape of plant roots comprises a step of transforming plant cells with recombinant expression vector containing OsIDD10(Oryza sativa Indeterminate domain) genes. The method comprises a step of suppressing the expression of OsIDD10 genes in which the plant roots coil up. A plant body having root shape which is controlled is prepared by transforming the plant with the recombinant expression vector. The plant body is a monocot plant. A composition for controlling the shape of the plant root contains OsIDD10 genes.본 발명은 OsIDD10 유전자의 발현을 식물체에서 조절함으로써 식물의 뿌리 형태를 조절하는 방법, 상기 방법에 의해 제조된 뿌리 형태가 조절되는 식물체 및 식물의 뿌리 형태 조절용 조성물에 관한 것이다.
