PETAL-SPECIFIC PROMOTER

摘要

PURPOSE: A promoter which petal-specifically induces expression of a foreign gene in a plant is provided to be used for transformation of various crops in a genetic engineering method. CONSTITUTION: A petal-specific promoter is a promoter of Nicotiana tabacum ANS(anthocyanidin synthase) gene of sequence number 1 or 2. The promoter induces the expression of petal-specific gene. The promoter has a base sequence of sequence number 3. A primer set for amplifying the promoter contains a primer of sequence number 4 and a primer of sequence number 5. A pBGWFS7-PNtANS expression vector contains the promoter. A method for petal-specifically expressing a foreign gene comprises: a step of preparing an expression vector containing the promoter and the foreign gene; and a step of transducing the expression vector to a plant.
