摘要
Methods for influencing pollen development by modifying the sucrose metabolism in transgenic plant cells and plants and generating male sterile plants by sucrose depletion in pollen. An expression of a protein has enzymatic activity of a sucrose isomerase in transgenic plant cells. Nucleic acid molecules 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 harvest products and the propagation material of said transgenic plants.
