Angélique Déléris @arabette.bsky.social · 22/01/2025In sum, we document an alternative control of TEs by H3K27me3 which is more plastic than DNA methylation, and that a TE can change epigenetic silencing state throughout its lifespan. This challenges the dogma that Arabidopsis TEs are solely targeted by DNA methylation in nature. 150
Angélique Déléris @arabette.bsky.social · 22/01/2025We show i) that some TEs are targeted by H3K27me3 (Polycomb) instead of DNA methylation in wildtype Arabidopsis ii) H3K27me3 can be deposited on newly inserted TE sequences iii) the existence of “bifrons” TEs that are marked by DNA methylation or H3K27me3 depending on the ecotype 120
