Really happy to see this one out: www.sciencedirect.com/science/arti... Alibek's drive & great coll w/ friends @gekaragoz.bsky.social & E. Hallacli resulted in a cool story that starts with our beloved #Marchantia and ends with iPSC-derived neurons 🤩🤪 A short 🧵

I have a PhD student and a post-doc position available in my lab to work on plant photobiology. Please use the links below to postulate.
Please RT, many thanks

Quantification of cell‐type‐specific plasmodesmata distribution in Arabidopsis roots reveals spatial and patterning dynamics Plasmodesmata are cytoplasmic channels essential for intercellular communication in plants; yet their organ-scale distribution and regulation remain poorly understood. Here, we establish a quantitati...

⚙️Technical Advance

How are plasmodesmata distributed across tissues? 🌱

Davis et al. developed a 3D quantitative imaging pipeline to map pit fields at cell-type resolution in Arabidopsis roots.
They’re developmentally reallocated and spatially patterned by BR signaling.

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.

Plants can sense when their barrier is injured—and repair it! 🌱
This stunning work, led by Hiroyuki Iida, shows that wounding is sensed through the diffusion of two gases: ethylene and oxygen.
I had the pleasure of contributing and see this project grow.

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.

I am very excited to share my simultaneous triple staining method for monocot roots. This method is not only faster but also utilizes a smaller volume of stain than traditional methods and minimizes mechanical tissue damage.

A plant ‘vaccine’ takes on corn rootworm, a fearsome pest Inoculating soil with pink microbes could help reduce the use of toxic insecticides.

Damage from corn rootworm costs an excess of $1 billion each year in the United States alone. Man P. Huynh et al. may have found a solution: doi.org/10.1094/PBIO...

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.

Plants use cell-surface and intracellular receptors that collaborate to detect pathogens🦠. We discovered that a key #ubiquitin recognition event recruits both receptor types into an unexpected dual receptor complex that boost the translation of defence proteins and establishes robust #PlantImmunity👇🏾
