Congrats to everyone!

The mechanical properties of Arabidopsis thaliana roots adapt dynamically during development and to stress Brillouin microscopy reveals in vivo dynamics of mechanical properties during plant development and response to stress.

Our work now on its final version. We mapped the mechanical properties of roots at tissue and single cell levels using Brillouin microscopy and molecular rotors. Additional mutants and stress measurements from what we previously showed in the preprint are included.

mRNA translation & plant fertility 🌱New
@theplantcell.bsky.social study led by Hafidh’s team (iebcas.bsky.social) in collaboration with Rémy Merret (remymerret.bsky.social), uncovers how eIF3E fine-tunes translation of specific mRNAs to control pollen tube growth and fertility.

CEPLAS starts a number of new projects, and we are looking for 12 Postdocs ❗
CEPLAS projects are always highly collaborative, that means postdocs working with us will always closely interact with several CEPLAS research groups. Find all postdoc openings here: www.ceplas.eu/en/training-...

Join us as a postdoctoral scientist to work with us and a team of excellent bioinformaticians (Björn Usadel´s Lab) to study barley meristems from all angles.

Fig. 1.Various types of root-to-shoot signals in salinity-stressed plants. Hydraulic and electrical signals constitute the category of Physical Signals. The illustration was created in MS PowerPoint and the plant icon was taken from Freepik (www.freepik.com).

🌊🌿 REVIEW 🌿🌊

This work provides a comprehensive summary of the current knowledge of root-borne long-distance signals that propagate through the plant and coordinate whole-plant adaptive responses to soil salinity - Gul et al.
