PROMOTER SBUBI2, PREPARATION METHOD AND USES THEREOF

摘要

Promoter of sweet sorghum BT×623 and its variants having promoter functions are provided, wherein the promoter has the nucleotide sequence shown in SEQ ID NO: 1, and the variants are variants selected from: 1) nucleotide sequences that hybridize with the sequence shown in SEQ ID NO: 1 under high stringent conditions, 2) nucleotide sequences that comprise a substitution, deletion, and/or insertion modification of one or more bases of the nucleotide sequence shown in SEQ ID NO: 1, and 3) nucleotide sequences that have at least 90% identity to the nucleotide sequence shown in SEQ ID NO: 1. Preparation methods of the promoter and uses thereof in regulating expressions of target genes in plants and in rice breeding are also provided.
