23 Jul METHOD FOR REDUCING POLLEN FERTILITY BY USING GENE OF TAPETAL LAYER SPECIFIC ZINC FINGER TRANSCRIPTION FACTOR
Abstract
PROBLEM TO BE SOLVED: To provide a gene engineering method useful for transforming a plant represented by male sterile by utilizing a specific gene in the tissue of an anther. ;SOLUTION: This method for producing the transformed plant is provided ty utilizing a plant expression cassette containing a promoter containing any one of the (a) a DNA having a specific base sequence (e.g. base sequence encoding ZPT3-2 derived from petunia) or (b) a DNA having a part of the sequence of (a) and exhibiting the the specific promoter activity of the tapetal layer of an anther, and a xenogenic gene bound to the promoter operably. According to the method, the plant including the promoter, and the promoter and the xenogenic gene imparts male sterility to the plant. ;COPYRIGHT: (C)2006,JPO&NCIPI
