Outline of Final Research Achievements

The goal of this research is to understand the molecular mechanism of cellular differentiation at the early stages of rice embryogenesis. We already demonstrated that, during the early stage of rice embryogenesis,
a receptor like kinase has pivotal function in cellular differentiation by using rice embryogenesis defective mutants (odm mutants). This suggests that a mobile signal could function in the process of cellular differentiation at the early stage of rice embryogenesis, because receptor like kinases are generally are important components of inter cellular signaling. In order to elucidate the entire components of the signaling module that operates at the cellular differentiation at the early stage of rice embryogenesis, we made double mutants with previously identified odm mutants. In addition, we screened and analyzed the suppressor mutations that restore odm phenotype.
