Outline of Final Research Achievements |
Genomes of vertebrates and plants contain a substantial number of transposable elements (TEs), which are often inserted in genic regions. In this study, we aimed to analyze genome-wide distribution of transposable elements in the model plant Arabidopsis thaliana. We showed that about 3% of TEs are intragenic, especially are inserted in intronic regions. Further study showed that epigenetic silencing of intronic repeats requires RNA-directed DNA methylation pathway, MET1 and DDM1.
