NEW RESULTS 🔬📢

Here's the latest version of our preprint, now with a whole new dataset on the role of BAK1 in nanoscale regulation of rapid hormonal responses.
Check out this interdisciplinary project using #AFM , #CarboTag based FLIM and #sptPALM superresolution!☺️

Distinct nanoscale dynamics of growth receptor complexes link hormone perception to rapid cell wall remodeling

Cell elongation is a fundamental process allowing plants to change size and shape, a process governed by several growth promoting hormones. While hormones such as brassinosteroids (BRs) and phytosulfo...

New Preprint!

We use #AFM and CarboTag-based #FLIM to describe rapid cell wall mechanisms of Phytosulfokines & Brassinosteroids and investigate how these processes are initiated on the nanoscale by using #sptPALM!

PS: This is also the main story of my PhD project😊✌🏻

The plant cell wall is obviously incredibly important, but tools for studying it in live plants at subcellular resolution are limited. In comes the CarboTag suite! They use
pyridine boronic acid to target dyes to the cell wall, and they do this for many colors.

I had some absolutely incredible papers come online this week, and I need to take a minute to post about each of them. First, let me tell you about the CarboTag probes for imaging plant cell walls! From the Sprakel lab (a short thread) www.nature.com/articles/s41...

Our new toolbox of plant membrane imaging probes: LipoTag. After CarboTag (cell wall probes), we have now developed a modular strategy to create non toxic, easy-to-use, and flexible probes for hassle-free live-cell imaging of plant membranes, and their tension, lipid order and oxidation. 🍀🔬
