23 Jul DXR promoter for lily flower part peculiarities and wound inductions and application of DXR promoter
Abstract
The invention belongs to the technical field of gene engineering and particularly discloses a DXR promoter for lily flower part peculiarities and wound inductions and application of the DXR promoter. The nucleotide sequence of the promoter is shown in SEQ ID NO:2. The target gene regulated by the DXR promoter is only expressed in the flower tissue in transgenic tobacco, and the expression of the target gene is related to the flower development process and is induced by damage and jasmonic acid methyl ester. In addition, the DXR promoter can be connected to any plant transformation carrier and guided into lilies or other plant cells, the transgene flowery flavor containing the promoter and resistance can be obtained, and therefore the promoter can be used for production. Peculiar molecular markers can also be generated according to promoter sequence information, used for identifying lilies or other plant flowery flavors and resistance gene types and used for molecular marker auxiliary selective breeding, and therefore the selecting efficiency of breeding is improved.
