Outline of Final Research Achievements |
To reveal the transcriptional regulation mechanism of retrotransposons, we carried out a screen of the mutants affected in the silencing at a transgene. We identified Arabidopsis gene affecting heterochromatin-associated silencing, KUMONOSU (KUN). KUN encodes a plant-specific retrotransposon related plant mobile domain (PMD), and affects silencing pathway by impaired condensation of pericentromeric heterochromatin. KUN acts for silencing independent of DNA methylation and known chromatin modifications.
