Abstract: The present invention relates to the field of biotechnology and plant breeding, and in particular relates to a method using plant cell proliferation regulator gene to induce haploid, and a use thereof in plant breeding. In the present invention, expression profiles of unfertilized egg cells of rice and rice embryos 5 days after fertilization are analyzed, and 2 genes are discovered to have relatively high expression, OsCPRO1 and OsCPRO2. The research shows that these two genes can be utilized to induce the production of haploid descendants. Specifically, a promoter specifically expressed in egg cells controls the gene to convert a plant, obtaining induced haploid plant material of a positive transgenic plant. Furthermore, the induced haploid plant material can be combined with a MiMe system to obtain apomixes material, and thereby generate clone seeds.
