🌱🧬Root surface epidermal cells sense mechanical tension & activate RAB-A5c-driven growth control. Covered cells are shielded by the root cap Plants use positional cues to link biomechanics with gene expression for directional growth. #plantscience @zoenv.bsky.social www.cell.com/current-biol...

Plant cells at the organ surface use mechanical cues to activate a specific growth-control program

Nemec-Venza et al. show how mechanical signals, such as tissue tension, can activate gene expression in epidermal cells at the surface of Arabidopsis roots. The expression of the edge-specific growth ...

This story is now published in @natplants.nature.com ! 🎉🎩 Check out the final article here: nature.com/articles/s41477-026-02361-1 Very similar to the original bioRxiv preprint, with the addition of some cool polysome analysis (in the supplementals)! Thanks and congrats to everyone involved! 🙏

Chloroplast-encoded small subunit extensions reshape the Chlamydomonas chlororibosome - Nature Plants

Using in situ cryo-electron tomography, researchers found a unique ‘arm’ domain on the small subunit of Chlamydomonas chlororibosomes. This discovery suggests that chlororibosome structure is more evo...

Long in the making, but happy to present the Chlamydomonas chlororibosome! Cryo-ET🔬reveals a large new domain on the small subunit, built from multiple extensions in conserved ribosomal proteins. bioRxiv 📖: shorturl.at/q44tG This suggests greater chlororibosome diversity than expected! 1/n 🧵

The cyanobacterium Acaryochloris marina can photosynthesize using far-red light at the edge of the visible spectrum. A new #ScienceAdvances study uncovers the basis of this system, offering insight into how plant photosynthesis could use longer wavelengths of light. https://scim.ag/43udhqY

Far-red chlorophyll d clusters extend photosystem I absorption toward the red limit

The cyanobacterium A. marina shows how photosynthetically active radiation can be expanded into the far-red spectral region.

COST Action PlantWallK@plantwallk.org · 3mo ago

A great way to close the #PlantWallK26 days in Prague! The EPCC satellite meeting wrapped up yesterday with a full day of scientific presentations and stimulating discussions on plant cytoskeleton. Many thanks to all contributors and participants, it was a pleasure to see the community in action.

Group photograph of EPCC satellite meeting participants, taken on 27 May 2026 in the entrance hall of a classical university building in Prague. Approximately forty attendees are arranged across several steps of a grand stone staircase, facing the camera. A small sign reading "EPCC — May 27.5.2026, Prague" is held at the front of the group.
