The regulation of reproductive organ initiation, identity, morphogenesis and reproductive success is crucial for the formation of a new functional plant. We aim to identify central genetic and hormonal pathways important for female and male reproductive organ development and function in the evolutionary very distantly related plant groups, bryophytes representing early diverging land plants and flowering plants. We have shown that the plant hormone auxin plays fundamental roles in reproductive organ development and function in both groups and that autophagy is a conserved mechanism in sperm development in the animal and plant lineages. We also aim to understand the genetic and hormonal processes necessary for embryo development in early diverging land plants.
