*PhD position in Plant Physiology at Stockholm University* We are looking for a new PhD candidate to join our new lab at Stockholm University! The project will focus on epigenetic regulation of reproductive thermotolerance. Please share🙏 More information: su.varbi.com/what:job/job....

The origin of MADS-box genes is fundamental to understanding the adaptative innovations of land plants. We are happy to have the opportunity for another round of clarification. Thank @genomebiolevol.bsky.social for providing the platform. Very professional editors and reviewers, much appreciated!

Qiu, Li & Köhler show that both Type I and Type II MADS-box genes are plant-specific duplicates derived from MEF2-type ancestors, while ancestral SRF genes were lost before the divergence of the plant lineage. 🔗 doi.org/10.1093/gbe/evag140 #genome #evolution #PlantSky

Our lab @mpi-mp-potsdam.bsky.social is hiring two postdoctoral researchers to join our ERC-funded GRAFT project on mobile small RNAs in plants. 🔗 Details: jobs.mpimp-golm.mpg.de/jobposting/b... 📅 Deadline: July 31, 2026 Please share!

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!

ERC 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!

First publication of the year! We set up an image-based quantification of seed phenotypes (here Arabidopsis thaliana). It comes together with a random forest classifier for our favorite phenotype, seed abortion.

I’m thrilled to share my latest research with @claudiakohler11.bsky.social in @mpi-mp-potsdam.bsky.social, now published in @natplants.nature.com ! In this work, we reveal that long-distance transported siRNAs from maternal sporophytic tissues are functional in pollen development and reproduction.
