How is epigenetic information inherited? We found that CDCA7 proteins are critical players in the inheritance of DNA methylation at CG sites in plants, and this is true both in the lab and in the wild. How does this work? 🧵👇
New paper! Work led by @p-bourguet.bsky.social and Frédéric Berger at the GMI of the @oeaw.bsky.social and @esasaki007.bsky.social identified how protein CDCA7 helps plants stably maintain epigenetic modifications across generations.
