How fast do plants actually grow? And which growth processes matter most for organ size?
We dived into 176 papers, extracted and re-analyzed the data so you don’t have to!

A multiscale growth atlas of Arabidopsis: linking cell dynamics to organ development
Plant development depends on coordinated growth at cellular and organ scales, yet comparative analyses are hindered by inconsistent reporting of growth across studies. We conducted a meta-analysis o.....

New paper!💡 Amir Ohad developed this nifty setup to measure weak forces generated by freely moving plants, based on the deflection of a pendulum (straw from the cafeteria 😎), which does not require any tethering of the plant: academic.oup.com/jxb/advance-...

One day in the lab, we accidentally discovered that the spines of a cactus 🌵 straighten when exposed to fog. I was intrigued and so were my collaborators. How does this work and what can be gained from it? Here are some of the answers in our new preprint:

🌿💻 Plant Models and Morphology 💻🌿

The 9th International Plant Computational Biology Workshop @slcuplants.bsky.social brought together mathematicians, computer scientists, physicists and biologists exploring plant development through models and simulations.

Huge thanks to organisers and speakers!👏

The BM^2 Lab is hiring a Ph.D. student to work on a variety of problems connected to modeling of morphogenesis in plants (i.e. ovule curvature formation, fixed handedness establishment in certain plant organs and its link to cell wall mechanics).

Please share!

Mody et al. review the study of the cellular basis of plant morphogenesis with 3D digital organs 🔬🌱

Fig. 1 (shortened, full legend in paper): Pipeline to generate 3D digital organs demonstrated using a stage 3-V Cardamine hirsuta ovule. (A) The generation of a 3D digital organ starts with 3D imaging of the organ of interest stained with a cell wall stain such as SR2200. The 3D rendering of a confocal laser scanning microscopy (CLSM) z-stack of ovule with SR2200-stained cell walls is shown. The bounding box shows the xyz imaging directions of the ovule in the 3D view (top panel).

Dreaming of a swimming pool? Bacteria are surrounded by water! Water capillary forces organize bacterial colonies into gas, nematic streams, or droplet states. New paper @natphys.nature.com led by Matt Black and Chenyi Fei, with Ned Wingreen and Josh Shaevitz!

Capillary interactions drive the self-organization of bacterial colonies - Nature Physics
Bacteria tend to live in thin layers of water on surfaces. Now the capillary forces in these layers are shown to help organize the bacteria into dense packs.

One of the key aspects influencing morphogenesis is mechanics. We mapped the mechanical properties of living roots at the tissue and cellular levels using Brillouin microscopy and molecular rotors.

1/14 How does an organ rebuild its shape after injury? It's not just about making new cells, but aligning them in the right direction — like bricks shaping a structure. We show that it's all driven by Cell Geometry!
