23 Jul Ginger flower floral specific and damage and pest induced TPS2 (Trehalose-6-Phosphate Synthase 2) promoter and application thereof
Abstract
The invention belongs to the technical field of gene engineering and particularly discloses a ginger flower floral specific and damage and pest induced TPS2 (Trehalose-6-Phosphate Synthase 2) promoter and an application thereof. The promoter has a nucleotide sequence as shown in SEQ ID NO: 2. A target gene controlled by the TPS2 promoter disclosed by the invention is only expressed in a flower tissue of a transgenic tobacco, and the expression is relevant to a flower development process and is induced by damage and pests. In addition, the TPS2 promoter disclosed by the invention can be introduced to a cell of a ginger flower or other plants after being connected to any one plant transformation vector to obtain promoter-containing transgenic fragrance and resistance to be used for production; or a specific molecular marker can also be generated according to the sequence information of the promoter disclosed by the invention and is used for authenticating the fragrance and resistance genotypes of the ginger flower or other plants and realizing the molecular-marker-assisted selective breeding, so that the breeding selection efficiency is increased.
