Kick-off meeting of our GreenRobust cluster of excellence last week. Exciting times ahead for plant sciences by bringing together an extraordinary bunch of enthusiastic scientists and human beings!
Fig. 1 (shortened, full legend in paper): Workflow of single-particle tracking photoactivated localization microscopy (sptPALM) analysis. (A) Localization: single molecule spots are cut out of the raw data image stack, fitted with two-dimensional Gaussian functions and the results (most importantly, their coordinates) stored as lists. (B) Tracking: single-molecule positions are grouped to tracks, based on their relative positions in subsequent frames. (C) Mean square displacement (MSD) analysis: the average squared distance the molecules have traveled in certain time intervals (top left) can be plotted in MSD curves (bottom), showing a straight line for free Brownian motion (dark gray), for which the slope is directly proportional to the diffusion coefficient. Other motion types like superdiffusive (red) or subdiffusive (yellow) show different curve shapes (inset: corresponding single-molecule example tracks).
🔬 EXPERT VIEW 🔬
Oven-Krockhaus et al. introduce single-particle tracking photoactivated localization microscopy for studying plasma membrane proteins in plants, outlining key applications and practical guidance on instrumentation, probes, and analysis.

#PlantSciences
This is exciting. Congratulations. I hope you will look at embryos as well 😀
PLANT BIOLOGY EUROPE meeting, Budapest, just started and people are already dancing! Great start!
#PBE2025
Well deserved #scicomm award at the MBP2025 meeting for @somssich.bsky.social ! Big congrats!
If you are interested in plant stem cell systems, meristems and development of cereals:
We are organising an international symposium on "Cereal Meristems and Stem Cell Systems", see attached announcement. www.cscs2025.de for more details
Walking home from work one day, you encounter a funny little man selling cabbages.
"Pathways" he says
"Secret portals to the biology realms"
"How odd" you think. But the cabbages do look delicious, so you buy a few.
Later that night you cut the first one open.
New Phytologist Stomata Seminar Video available (by Sally Assmann and myself). Thanks again for this fantastic opportunity to share our work and perspectives 🌱🥰!

Perspectives on a co-option of a familiar signaling pathway for embryo patterning, where phosphorylation of SCREAM by MPK3/6 triggers different outcomes. But..Symmetric Cell Division is EXCITING and essential for generating a mirror-symmetric Guard Cell pair😘🌱.

BPMs regulate Arabidopsis seedling development by promoting auxin-independent degradation of the Aux/IAA protein IAA10 https://www.biorxiv.org/content/10.1101/2024.11.26.625463v1
By definition, enhancers can activate from a distance. But with increased distance between enhancer and promoter, the activation drops. To study this systematically, we build a synthetic locus: www.cell.com/molecular-ce... 1/12
We just completed our cluster interview at @dfgpublic.bsky.social. Exceptional team spirit and a fantastic joint achievement by everybody involved! The GreenRobust initiative in full swing.
More details on our recent pre-print:
Alignments of stomata have been described in many species, here are 2 examples: Thym from my kitchen, and Leucadendron from a 1935 paper (Smith 1935 on the orientation of stomata)
What is directing these alignments is unknown 1/12

Repost if BlueSky is now your primary social media site.
On the way to @debbiemleigh.bsky.social 's excellent seminar talk this afternoon. If you like geometry this part of @unituebingen.bsky.social campus is good for you...
Super excited to announce that our SCRM story is officially published!!! 🎉🎉🎉
