| Outline of Final Research Achievements |
A genome-wide dynamic gene-response mechanism, epigenetic gene-regulation, was observed under aluminum (Al) stress in Arabidopsis thaliana. We furthermore confirmed that two general key-genes in epigenetic gene-regulation, AvSAMS1 (Andropogon virginicus S-adenosyl methionine synthase) and Suvh4 (Histone H3 methyltransferase), are actually related to the alteration of methylation status in both DNA and histone H3 protein under Al stress in this plant. Since an alteration of methylation status in DNA was also observed in rice genome (cultivar Nipponbare) under this stress, we strongly suggest an existence of similar epigenetic gene-regulation systems in various plants under Al stress.
