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! 🤯

ONLINE COVER: Leaves of Kalanchoe thyrsiflora, a member of the Crassulaceae family of succulents also containing Kalanchoë laxiflora. Stomata, otherwise known as plants’ breathing pores, allow gas exchange between plants and the atmosphere, but little is known about how succulent stomata are formed or move. Cheng et al.’s investigation into K. laxiflora revealed that subsidiary cells can support the opening and closing of stomata and that the transcription factor MUTE, which drives stomatal development, also facilitates additional rounds of asymmetric division needed to generate subsidiary cells. Their work provides insight into succulent development and could be applied in agricultural contexts to engineer water conservation strategies.

🌵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 👇

It’s been amazing to receive so much interest in the Prototaxites paper! An absolute highlight was talking about the work last night to Jane Hill on BBC R4, The World Tonight The Prototaxites segment starts at 33 mins 👇👇 www.bbc.co.uk/sounds/play/...

Non-seed science is accelerating forwards at a truly impressive rate. Thanks to @philcarella.bsky.social and Kayla Robinson for an awesome #nonseedUK25 meeting, and to @justingoodrich.bsky.social and @sandyheth.bsky.social for agreeing to organise #nonseedUK26 in Edinburgh - looking forward to it 👍

Thanks to everyone who came along to the #nonseedUK25 meeting. Another fantastic day of non-seed science. Thanks to @philcarella.bsky.social and Kayla Robinson for looking after us all so well 👍
