Excited to share this preprint on the microtubule severing protein Katanin, and its role in cell elongation and division in maize. First author Stephanie Martinez worked collaboratively with many folks to bring you this preprint. Check it out! 🔬🌽 www.biorxiv.org/content/10.1...

KATANIN promotes cell elongation and division to generate proper cell numbers in maize organs

Microtubule severing is essential for proper eukaryotic cell elongation and division. Here we show that the microtubule severing protein, KATANIN, is encoded by two genes in Zea mays (maize) called Di...

Have you ever wondered how microtubules withstand and respond to mechanical stress in cells?

Here we show by in vitro reconstitution assays that MAP65-1 and PRC1 promote microtubule nucleation on existing lattices, especially on those with structural irregularities linked to mechanical stress.

Despite their high rigidity, microtubules (MTs) dynamically bend and buckle in cells. MT-self repair is inherent to their metastable nature, but it remains unclear whether just inherent repair mechanisms are sufficient to maintain MT integrity🧵 (1/9)

Exciting new work from the #Schaedel lab on the limits of microtubule self repair > will help us understand how #microtubules experiencing extreme compression in crowded 3D environments resist or give way.

Happy to share that our paper on Tau- Microtubule interaction is now published in Nature Physics!🥳

We show that Tau isn’t just a microtubule stabiliser - it promotes removal of defects in the microtubule lattice.

Congratulations @subhambiswas.bsky.social!

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!

🌱✂️ How do plant cells decide where to divide?

Our work shows that actin can override the geometric rules—guiding cells to divide in alternative orientations.

The Francis Crick Institute @crick.ac.uk · Jun 25

Crick researchers have shown that the ‘pacemaker’ controlling yeast cell division is located inside the nucleus, rather than outside it as was previously thought.

This research was led by @nitinkapadia.bsky.social and Paul Nurse.

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
