Promoter from rice and application thereof

The invention discloses an HDT702 promoter and application thereof. The HDT702 promoter is obtained from cloning of rice, and the nucleotide sequence of the HDT702 promoter is shown in SEQ ID NO.1. The promoter is a tissue specificity promoter and can promote the specific expression of downstream genes in anther of rice. The HDT702 promoter is applied into the transgenic engineering, so that an expression product of target genes is specifically accumulated in the anther, and the local expression amount is increased; and meanwhile, unnecessary waste of plant nutrients can be avoided, and therefore good application prospects can be achieved in the transgenic engineering.
