Our preprint on sex determination in Cannabis - now updated with a strata analysis and new gene expression data.
Great collaboration with @tatianagiraud.bsky.social and her team!

Nice!

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.

Giant cells: from random initiation to nonrandom pattern

Our recent paper is explained here in a more accessible way!

"We often think of the emergence of order as arising from self-organization or cell–cell interactions, but here, order emerges from random cell fate decisions amplified by the geometry of tissue growth."

Dear PPRM community, we are pleased to invite you to the next PPRM meeting, 14-16 September 2026 in Freising, Germany.

Nighttime photo of a modern building with illuminated windows and bare trees in front. Above the building, green aurora lights stretch across the sky, blending into a purple‑red night sky. Stars are visible as well

With this throwback to the #northernlights at our Weihenstephan #campus last month, we want to wish you the best of luck for your exams and a wonderful #semesterbreak! 🍀🤩 Thanks to Julia Keberle for the campus #photoofthemonth for January.

Evolution and development: What makes a merry stem? From tiny mosses to giant redwoods, around 450,000 species of land plants show a huge variety of forms, yet all land plants develop from stem cells in proliferative meristems. What makes a meristem? T...

It was good to catch up on my reading for this dispatch in Current Biology. Sjoerd Woudenberg in the Weijers lab, Wallner et al. In the Dolan lab and Flores Sandoval et al. In the Bowman lab have done a great job! Evolution and development: What makes a merry stem?: www.cell.com/current-biol...

Duckweeds are an important plant research model but have been challenging to modify genetically. A study published in @newphyt.bsky.social by the Marí-Ordóñez group at the GMI, presents a new and highly reproducible method for genetic transformation in the duckweed species Spirodela polyrhiza.

You don’t need a brain to benefit from a good night of sleep. Despite lacking a central nervous system, jellyfish and sea anemones have sleep patterns remarkably similar to those of humans, researchers report.

Imputation integrates single-cell and spatial gene expression data to resolve transcriptional networks in barley shoot meristem development - Nature Plants Spatially resolved gene expression during barley development was done by integrating an scRNA-seq dataset from cells with unknown position with spatial transcriptomics. This dataset is publicly availa...

It's finally out!...
Using single-cell and spatial transcriptome data, and data imputation, we created BARVISTA, a website able to perform almost genome-wide information on gene expression profiles at single-cell resolution in barley spikes!

If they review by AI can we let AI write the proposal?? 🙃🫣

a black background with the word idiocracy written in white letters . ALT: a black background with the word idiocracy written in white letters .

Dear @dfg.de So, I will spend months writing a grant and you will let people judge it with AI tools that are trained on predatory journals like Frontiers, MDPI or alike that are practically not peer-reviewed??? Is this how you will select cutting edge science??? #idiocracy

Just in time for Christmas a new paper in @plantspeopleplanet.bsky.social by @joannakacprzyk.bsky.social and myself.
We asked 421 plant scientists why they study plants!
Check it out and also check @plantmemories.bsky.social where we post lovely survey responses.

Advanced grad students + postdocs: apply for the 2026 #kitpqbio summer course, "Physical Principles of Morphogenesis in Plants and Animals," at buff.ly/OXXMKEv. Apply by Feb. 1.
