abstract |
The invention discloses a Nicotiana tabacum NaD1 gene promoter and application. The promoter has the nucleotide sequence shown in SEQ ID NO:1. The present invention also provides vectors and host cells containing the promoter, the present invention also relates to nucleic acid constructs, vectors, recombinant cells, transgenic plants, explants and calli containing the promoter, and the present invention also discloses use of the promoter. The advantage is that the promoter contains light-responsive elements, and light stress treatment can significantly change the expression of NaD1 gene in flowers. Studying the regulation mode of this promoter is of great use in utilizing NaD1 protein more efficiently. |
