Zusammenfassung:The invention discloses a promoter, in particular to a promoter of monocotyledon like rice and a preparation method and an application thereof. The promoter has a nucleotide sequence disclosed by SEQ IDNO:1 or is provided with the following variants with the promoter function: 1) a nucleotide sequence hybridized by the nucleotide sequence disclosed by SEQ ID NO:1 under the high-grade tight condition; 2) a nucleotide sequence which is obtained by performing substitution, deletion and addition decoration of one or a plurality of basic groups on the nucleotide sequence disclosed by SEQ ID NO:1; and 3) a nucleotide sequence which has 90% sequence identity with the nucleotide sequence disclosed by SEQ ID NO:1. The invention also relates to the preparation method of the promoter and the application of the promoter in controlling target gene expression and rice breeding in the monocotyledon.
