The application discloses a method for preparing rice with changed tiller number, and belongs to the technical field of genetic breeding. The method comprises the following steps: introducing a coding gene of an OsD14 mutant into target rice to obtain rice with changed tiller number, wherein the tiller number of the rice with changed tiller number is higher or lower than that of the target rice, and the OsD14 mutant is a protein obtained by mutating the 10th, 11th, 13th and 15th amino acids in SEQ ID NO: 1 into other amino acids and keeping other amino acids in SEQ ID NO: 1 unchanged. It is proved by experiments that whether ubiquitination degradation of the OsD14 occurs is related to a phosphorylation state of the OsD14, the number of rice tillers is adjusted by using the phosphorylation state of the OsD14, and the plant type is improved, so that the yield of the rice is improved, and the method has a wide application prospect.

This invention provides a gene for Brassica napus resistant to the sulfonylurea herbicide bensulfuron-methyl, encoding the amino acid sequence shown in SEQ ID NO:2, exhibiting resistance to the sulfonylurea herbicide bensulfuron-methyl. Preferably, the nucleotide sequence of the Brassica napus resistant gene to bensulfuron-methyl is shown in SEQ ID NO:1. The invention also provides the application of the above-mentioned Brassica napus resistant gene to bensulfuron-methyl in detecting plants, plant cells, or plant tissues resistant to the sulfonylurea herbicide bensulfuron-methyl, and in cultivating plants, plant cells, or plant tissues resistant to the sulfonylurea herbicide bensulfuron-methyl. The Brassica napus resistant gene to bensulfuron-methyl of this invention provides stable resistance to the sulfonylurea herbicide bensulfuron-methyl. Brassica napus with this gene recovers quickly from herbicide damage, exhibits excellent plant type, normal fruit setting, and can be safely used at the recommended field concentration.
