Abstract (en)

[origin: WO0159135A1] The invention relates to a method for influencing the pollen development by modifying the sucrose metabolism in transgenic plant cells and plants. The invention relates especially to a method for generating male sterile plants by sucrose depletion in pollen. The invention relates particularly to the expression of a protein having the enzymatic activity of a sucrose isomerase in transgenic plant cells. The invention also relates to nucleic acid molecules that contain a DNA sequence encoding a protein having the enzymatic activity of a sucrose isomerase, wherein the DNA sequence is functionally linked with the regulatory sequences of a promoter active in plants so that the DNA sequence is expressed in anthers or pollen. The invention further relates to transgenic plants and plant cells that contain the inventive nucleic acid molecule and whose male plant and plant cells are sterile due to the expression of the DNA sequence that encodes a protein having the enzymatic activity of a sucrose isomerase. The invention also relates to the harvest products and the propagation material of said transgenic plants.
