Epigenetics, and transposons in the plant.
🧬 New on bioRxiv! 🧬 We developed SirenScan – a computational framework to systematically identify siren RNAs from sRNA-seq data.

Dfam Database of Transposable Elements@dfam.bsky.social · 4mo agoA New Open Foundation for TE Research: GIRI is transitioning the full Repbase collection to an open-access license and joining the Dfam effort to help build a unified open resource for transposable element research. Full announcement: tinyurl.com/48665xss
Thrilled to have received an ERC Advanced Grant to investigate the mechanisms and biological impact of small RNA mobility in plants. A huge thanks to my team for making this possible, and to the reviewers for their support and confidence in the project. Looking forward to getting started!
Tobias Lortzing@tlortzing.bsky.social · 4mo agoERC Advanced Grant @erc.europa.eu for @maxplanck.de Director Claudia Köhler @claudiakohler11.bsky.social! She receives 2.5 million euros to study how mobile small RNAs can impact adaptive functional traits in plants. Congratulations!

New OA Letter: "An active Helitron transposon family in wheat" rdcu.be/foNPA Heat stress and reduced DNA methylation can mobilize a Helitron family. Its mobilization is genetically linked to a specific full-length member catalysing the full Helitron life cycle. #PlantScience
Huge thanks to everyone involved—it's great to see this project finally released!
Etienne Bucher 🌾🧬🇪🇺@plantepigenetics.ch · 5mo agoWe just published our new paper about an active Helitron transposon in wheat 🌾🧬 We found that it can be mobilised by heat stress when DNA methylation is reduced. We document its full lifecycle: RNA -> circular DNA -> integration www.nature.com/articles/s41... #TEsky
New paper in @natplants.nature.com finds that #siRNAs can act as long-distance communication signals from maternal to male tissue in #Capsella with functional role in #pollen development. Read here: nature.com/articles/s41477-026-02219-6 @claudiakohler11.bsky.social @jiali024.bsky.social
Long-distance transport of siRNAs with functional roles in pollen development - Nature Plants
This study shows that many small RNAs in Capsella rubella pollen originate from maternal tissues. These mobile small RNAs support proper pollen development, revealing that non-cell-autonomous small RN...

Super cool findings. TE may do more things than we expect with host. I recalled LTR-RT (PopRice🌾) extrachromosomal DNA 🧬act as the sponges of TF ABI5 in the terminal tissue endosperm that does not inherit its DNA. Which regulating the development of rice seed-to-seedling transition.

Gag proteins of endogenous retroviruses are required for zebrafish development www.pnas.org/doi/10.1073/... Led heroically by Sylvia Chang & @jonowells.bsky.social A study which has changed the way I think of #transposons! No less! 🧵 1/n
