Abstract

Described is the use of the promoter region of the DefH9 gene of Anthirrhinum majus or of a promoter of a homologous gene displaying the same expression pattern and characteristics for the establishment of parthenocarpy or female sterility in plants, for increasing gynogenesis or for enhancing fruit setting and development. Also described are recombinant DNA molecules comprising a DefH9 promoter in combination with a DNA sequence which upon expression in plants leads to the above mentioned effects. Furthermore, described are plant cells and plants transformed with such recombinant DNA molecules.
