How do #stemcells integrate information to coordinate fate decisions? Delighted to finally see our work showing how growth factors regulate the mechano-osmotic state of the #nucleus and #chromatin to control #pluripotency exit out! www.nature.com/articles/s41... see 🧵 👇

Mechano-osmotic signals control chromatin state and fate transitions in pluripotent stem cells - Nature Cell Biology

McCreery, Stubb et al. show that mechano-osmotic changes in the nucleus induce general transcriptional repression and prime chromatin for cell fate transitions by relieving repression of specific differentiation genes.

It was already known that auxins (surprise!) had a key role controlling the end of flowering, plant menopause. Now we can tell you how and where they act in the inflorescence meristem to control the process.

Local regulation of auxin-related pathways in the shoot apical meristem plays a major role during proliferative arrest

González-Cuadra et al. show that repression of auxin-related pathways locally in the SAM is key in the control of proliferative arrest. FRUITFULL regulates these pathways to promote meristem arrest. B...

🌱✂️ How do plant cells decide where to divide?

Our work shows that actin can override the geometric rules—guiding cells to divide in alternative orientations.

How plants sense injury in their barrier tissue, periderm? Painstakingly detailed and amazing work by post doc Hiroyuki Iida shows that wounding is sensed by the diffusion of two gases: ethylene and oxygen. @treebiocoe.bsky.social‬ @erc.europa.eu‬ 1/x 🧵 www.nature.com/articles/s41...

Plants monitor the integrity of their barrier by sensing gas diffusion - Nature

A study using Arabidopsis shows that plants can monitor the integrity of their outer barriers by sensing gas diffusion, enabling them to initiate wound repair to prevent water loss and pathogen entry.
