Outline of Final Research Achievements

DNA demethylation plays important roles for many aspects of plant development and gene expression control related to environmental adaptation. In this study, we identified the cytosolic iron-sulfur cluster assembly (CIA) genes that are required for activation and DNA demethylation of the maternally expressed imprinted genes in the central cell of the femalegametophyte in A. thaliana. Our detailed analysis using one of the mutation in the CIA components revealed that this pathway also controls genes for plant immunity and stress tolerance in vegetative tissues.
