Outline of Final Research Achievements

Mechanisms regulating early phases of plant embryogenesis are poorly understood. We have previously identified a member of the plant-specific RKD transcription factors, RKD4, as a regulator of early embryogenesis in Arabidopsis thaliana. The present study revealed that RKD4 directly binds to the genomic DNAs of many genes including known regulators of embryogenesis, and thereby regulates their expression. In addition, genetic studies using liverworts and Arabidopsis indicated that RKD factors are evolutionarily conserved regulators of germ cell differentiation in land plants.
