Our preprint now peer-reviewed and published 🌾🔬🧬 Grasses have a signature short-long leaf epidermal pattern: small stomata & hair cells spaced by long pavement cells, but how is it built? Premitotic BdPL1 sets cell-size asymmetry; postmitotic BdBRX-solo/BdYDA1 enforces fate. doi.org/10.1016/j.cu...

🌾 Every grass leaf shares the same repeating short-long cell pattern in its epidermis. Our new #preprint identifies the protein that builds it. 🔬🧬 📄 preprint: www.biorxiv.org/content/10.6... 🧵⬇️ 1/11

For the last 34 years I have been on the faculty of the UNC-Chapel Hill Department of Biology and have never regretted that decision. This year we are hiring TWO new Assistant Professors in the broad area of Molecular, Cell, Developmental Biology 1/n bio.unc.edu

Our latest paper on building models of cell fate decisions -with David Rand, Marine Fontaine & @joadelas.bsky.social- combines developmental biology, dynamical systems theory and bioinformatics. I wrote a short piece to summarise it & explain ideas behind the approach briscoelab.org/blog-quantif...

Super cool exploration of stomatal bHLH gene evolution in ferns and gymnosperms. A decade ago Anne Vatén @stomagenesis.bsky.social already knew these plants were critical missing links -- now her group has functional studies in spruce! www.biorxiv.org/content/10.1...

2/ Plants love to multiply TF families — great for regulatory power, but how do factors that bind the same DNA sequence have different effects? Andrea Mair's hypothesis: specificity comes from each TF's protein partners.

1/9 🧵New preprint from the lab! A midpoint in a long journey to understand specificity among bHLH transcription factors in plants. Part IV: how does an accessory domain guide specificity of heterodimerizing bHLHs? #PlantSci #TranscriptionFactors #stomata www.biorxiv.org/cgi/content/...

Our first Kalanchoë laxiflora story found its perfect home @Science Advances with a beautiful cover image of Kalanchoë thyrsiflora leaves. I am grateful that I can continue working with this incredible new model to learn more about succulent development 🤩 www.science.org/doi/10.1126/...

Heike Lindner@heikelindner.bsky.social · 2y ago

This story was only possible through true team effort. Team Kalanchoë with Xin at the forefront. @jameshartwell.bsky.social, the most generous scientist who shared resources and answered countless questions. Read about MUTE during stomatal development in Kalanchoë www.biorxiv.org/content/10.1...

Our first study on how the leaf succulent Kalanchoë laxiflora makes stomatal subsidiary cells is finally peer-reviewed & out - and it made the cover! 🌵 🧬 🔬 doi.org/10.1126/scia... Despite 150 years of evolution, grasses and Crassulacean succulents use the SAME gene to make subsidiary cells! 🤯

Michael Raissig@michaelraissig.bsky.social · 2y ago

🌵Preprint alert 🌵 5y in the works & extremely proud of this one. Xin Cheng & @heikelindner.bsky.social established the eudicot leaf succulent Kalanchoë laxiflora as a dev model. Like in grasses, MUTE makes Kalanchoë’s stomatal subsidiary cells! 1/n www.biorxiv.org/content/10.1... BSKY-tutorial 👇

Our Editor, @swathiarur.bsky.social, has curated a new subject collection for the journal, highlighting the intersection between developmental and cell biology. Take a look at the collection 'Cell biology in development' here: journals.biologists.com/dev/collecti...

Our Review "Development, Anatomy and Integrated Function of Grass Leaf Veins and Graminoid Stomata" is out doi.org/10.1146/annu... Alec Baird and I discuss the development and function of the anatomical structures that regulate water supply (leaf veins) and water demand (stomata) in the grass leaf.
