Outline of Final Research Achievements |
In plant genomes, many transposable elements (TEs) are accumulated in genic regions including intron and untranslated regions (UTR) of genes. In this study, we investigated cryptic promoters that are regulated by epigenetic modifications. In Arabidopsis thaliana, we identified more than 3000 novel transcription start sites (TSS) that are epigenetically regulated, most of which are derived from TE sequences.
