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.

The present invention discloses the application of the lotus NnSAUR36 gene in improving plant height, stem strength and biomass, and belongs to the technical field of plant genetic engineering. The nucleotide sequence of the lotus NnSAUR36 gene of the present invention is shown in SEQ ID NO.4. The present invention finds that the lotus NnSAUR36 gene (Nn1g01094.1) can positively regulate plant height, stem strength and plant biomass. By overexpressing the gene, the lodging resistance of the plant can be significantly improved, the plant type can be improved and the plant biomass can be increased. The gene has important application prospects and provides a new way for molecular breeding and genetic improvement of lotus and other plants.

The invention 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, 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 of SEQ ID NO: 1 from serine to another amino acid and keeping the other amino acids of SEQ ID NO: 1 unchanged. Experiments prove that whether the OsD14 is subjected to ubiquitination degradation or not is related to the phosphorylation state of the OsD14, and the phosphorylation state of the OsD14 is used for adjusting the tillering number of the rice and improving the plant type of the plant, so that the application prospect is wide when the yield of the rice is increased.

The invention belongs to the technical field of plant biology, and particularly relates to a larch LkWox2 gene coded protein and application thereof in plant type improvement. The technical problem to be solved by the invention is to provide a new choice for larch breeding by exploring a Wox transcription factor in larch. The technical scheme of the invention is as follows: the protein coded by the larch LkWox2 gene has an amino acid sequence as shown in SEQ ID No.2. Through overexpression of the LkWox2 gene, it is found that the gene can promote differentiation and regeneration of plant leaf disc calluses and growth of buds; growth of lateral roots and adventitious roots of plants is promoted; the plant height is also reduced, and the internode is shortened. The invention provides a new breeding direction and method for obtaining plant varieties with fast growth, high survival rate and excellent plant types.

The purpose of the present invention is to provide a gene or protein that can regulate rice panicle type for use in rice molecular breeding. Based on the above purpose, the present application provides an application of a protein OsCWIN5 in regulating rice panicle type.
