NUCLEOTIDE SEQUENCES AND METHODS FOR THE SPECIFIC EXPRESSION OF GENES IN THE FEMALE GAMETOPHYTE, FEMALE REPRODUCTIVE CELLS, POLLEN GRAIN AND/OR MALE REPRODUCTIVE CELLS OF PLANTS

摘要

The invention relates to the localisation and expression patterns of promoters (regulatory nucleotide sequences) which act in a specific manner in the female gametophyte, the female gametes, the male gametophyte and/or the male gametes of Arabidopsis thaliana. The invention also relates to the methods that were used to identify the aforementioned promoters as well as the methods of using said promoters in expression constructions and to manipulate the reproductive development of plants. According to the invention, the identified, isolated promoters can be used to regulate the genic expression of selected genes in plants, so that such genes can be efficiently transcribed in the female or male reproductive cells of same. Said promoters can be used to prevent the transfer of transgenic traits to plants through in-field pollen in order to provide the seed with additional nutrients and to confer resistance to pathogens and diseases to the seed.
