Outline of Final Research Achievements

Through genetic characterization of histone demethylase genes IBM1 and LDL2 of Arabidopsis, we showed importance of gene body H3K4me1 for establishment of epigenetic states (Inagaki et al 2017). Characterization of hypomethylation mutant revealed genome-wide negative feedback to control global level of heterochromatin (Ito et al 2015). Furthermore, we showed behavior and evolutionary dynamics of sequence-specific anti-silencing systems of VANC proteins and their targets (Hosaka et al 2017).

Academic Significance and Societal Importance of the Research Achievements

遺伝子のON/OFF状態が細胞分裂後にまで継承される「エピジェネティック」な遺伝子制御は個体発生やゲノム進化の理解に重要なだけでなく、農学や医学にも重要である。本研究では、遺伝子ON/OFF状態の決定にヒストンタンパク質修飾の相互作用が重要であることを示し、また、エピジェネティックな抑制を除くタンパク質とその標的配列を同定した。得られた知見は、エピジェネティックな機構の理解とともに、それを制御する技術にもつながりうるものと期待できる。
