Transcriptional control of meiotic recombination by the DREAM complex Meiotic chromosome segregation and recombination, essential for sexual reproduction and evolution, require a specialized gene set. However, how meiotic gene expression is controlled remains largely un...

BUT: restoring MER3 can partly rescue fertility. With DREAM’s role conserved from plants to animals, we’re excited to shed light on how reproduction is orchestrated across multicellular life! 🌱🔬✨ #Meiosis #Science #PlantBiology

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.....

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!

Why plant embryos do not differentiate stomata? Discovery of the key peptide hormone. Embryo-specific peptide EPFL8, perceived by ERECTA, inhibits SPCH in a TMM-independent manner. Excellent work by the Torii Lab alumnus, Prof. Xingyun Qi. Congrats🌱🔬!

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...

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...

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)

Fresh from the @schaedellab.bsky.social 🔬

@fritzlaylin.bsky.social et al. propose a simple way to highlight both experimental #reproducibility & cell-to-cell variation, while avoiding pitfalls common in analysis of cell biology data rupress.org/jcb/article/...

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.
