The Fate of the Male Germ Cell

THE FASCINATION The male germ cell is the only cell of the human organism that leaves the body when it has achieved its final, highly sophisticated structure and properties. The male germ cell is designed for one purpose only: to reach the female gametes and to fertilize them. The various stages in the development of the male germ cell are characterized by proliferative phases, by the recombination of the maternal and paternal chromosomes, and by the differentiation and development of a specialized transport vehicle, the spermato zoon. Furthermore, the establishment of a special pool of stem cells, the spermatogonia, guarantees the continuity of the sperm-generation process from puberty to old age. THE FATE OF THE MALE GERM CELL The destiny of any individual germ cell is determined by a program that we know only in fragments. On the one hand every human male is able to produce many billions of germ cells in his lifetime, yet the chance of any single sperm reaching and fertilizing the female germ cell is exceedingly rare. A fertility disturbance means that somewhere during the complicated playing out of the germ cell program mistakes are made, and the program fails. It is still a fact that more than 50% of men presenting with male factor infertility have to be diagnosed as idiopathic, largely because of our lack of knowledge and conse quent lack of appropriate diagnostic tools.

The pollen grain is responsible for the production and delivery of sperm cells to the female gametes in flowering plants. Early in pollen development, there is an asymmetric division that is critical for the specification of the male germ cell. In this germ cell, shortly after the division, the transcription

Sexual reproduction in flowering plants involves the production of male and female gametes crucial for successful fertilisation, yet molecular mechanisms in these processes are largely unknown. The goal of the research presented in this thesis is to understand more about these mechanisms. A novel pollen division mutant, duo pollen 4
