Ever stretch a plastic bag until it wrinkled? Keeping a thin sheet flat while it rapidly expands is surprisingly difficult. So how do growing plant leaves remain flat as they rapidly grow? Check out our new @currentbiology.bsky.social review, How to Grow a Flat Leaf www.cell.com/current-biol...

Plants are unique in that single somatic cells have the remarkable potential to dedifferentiate and regenerate entirely new plants. However, the cell types and regulatory dynamics enabling dedifferentiation competence have not been fully explored... until now ⬇️ (1/12)

#dedifferentiation depends on cell type. This is what happens when you make protoplasts 👌

How do cells break symmetry to generate new shape and form? Using the apical hook as a model, we @joeecker.bsky.social applied spatial and single-cell multiomics, and identify a regulatory hotspot in a transient cell niche that drives this U-shaped structure 1/8 bsky.app/profile/bior...

Thrilled to announce our newest preprint on #dedifferentiation in Arabidopsis 🧬🌱. We used scRNA-seq and hormone treatments to track transcriptional reprogramming in diverse somatic cell types and found what we think is some pretty cool biology. Feedback welcome! www.biorxiv.org/content/10.6...

Excited to share that I will be opening my lab this fall at the @weizmanninstitute.bsky.social in the Department of Plant & Environmental Sciences! I am looking for postdocs interested in plant biology, stress biology, and single-cell technologies. #PlantBiology #SingleCell #Epigenomics #Postdoc

I would encourage plant genomics folks to attend -- organizers are interested in more plant people, and while you have to listen to weird things like cancer, there's lot of technologies and ideas that plant folks could benefit from hearing.

We are very happy and proud to present a study led by @jorgehg.bsky.social (now PI in Madrid – keep an eye on him!) in our team @bic-wur.bsky.social. In this work, we discover how auxin-regulated ARF transcription factors learned to activate transcription. A 🧵…(1/17) www.biorxiv.org/content/10.6...

A clear/significant finding derived from the single cell (sc) analysis of biological systems has been the realization that phenotypically homogeneous populations are heterogeneous at the level of gene expression (GE). www.cell.com/fulltext/S00... 🧵

This a very important, and extremely well-executed study from Ralph Grand’s group @uniheidelberg.bsky.social. Congrats to all the authors! www.biorxiv.org/content/10.6...

The maize community is so privileged to have the amazing support of @maizegdb.bsky.social. I don’t think we could do most of what we do without them. Check out their most recent work including large dna model prediction of effects here academic.oup.com/genetics/art...

Thank you, Vanessa, Mike and all involved! So many cool findings described in this work, including parallel evolution of leaf shape and the rapid radiation of Scalesia after genome doubling and Galápagos arrival.

Intrigued by a long-standing conundrum in small RNA biology—how nuclear Argonaute proteins silence transposons when they *need* target transcription for their own recruitment—we studied the piRNA pathway. And found a hidden RNA-decay axis from Piwi to the RNA exosome.
