So happy to see this work finally online! In this Research Review, I discuss the emerging roles of H3K27me3 writers (the enzymes that lay it down) and erasers (the enzymes that remove it) in controlling plant adaptation 🌿🌡️❄️🦠 nph.onlinelibrary.wiley.com/doi/10.1111/...

We just released a new major version of TrackMate (v8), the cell and organelle tracking plugin of Fiji. It ships many new features, detailed below, but that are articulated around the following:

A privilege to attend the 9th annual Computational Plant Biology workshop last week at @slcuplants.bsky.social heard inspiring talks, got direct help and advice with pipeline bottlenecks and explored some very pretty places!

Nice to see a small summary of our research findings in the Plantae Research Weekly! ☺️🌱

This might be one of the simplest images I captured, but very fascinating nonetheless, as it shows how tight the cytoplasm in a plant cell is. The cytosol and all other organelles are squished between the plasma membrane (magenta) and the central vacuole (its membrane is green) #MicroscopyMonday

I'm happy to share new work in collaboration with Elena Koslover's lab! First author Keaton developed a mathematical framework for diffusion of soluble material through mitochondrial networks. Then, Lewis lab PhD candidate Camryn used live cell imaging to parameterize... 1/3

Mitochondrial transfer is a fascinating phenomenon where cells shuttle mitos. The therapeutic potential is compelling and observational science is solid but the mechanism is a black box. Excellent Viewpoint in @naturemetabolism.bsky.social breaks down one of cell biology’s biggest emerging mysteries

The only meeting I’ve ever been to with a fun fair at night! #brumforever #NGS2025

It’s been a wonderful meeting so far at #NGS2025 the ECR community is a great place to be right now, and we’ve had some fascinating talks and workshops. Loved presenting my work on mtDNA and mito dynamics #plantscience

Please RT! Call for Fellows! If you’re a structural biologist and wanting to start your lab by applying for an external Fellowship then we at Imperial may be excited to host you. Synthetic biologists too.. Please submit expression of interest with details below 🙏 www.imperial.ac.uk/media/imperi...

Got papped yesterday at the @biology.ox.ac.uk research showcase spreading the good word about mitochondrial dynamics! So fun being in the new LaMB building and interacting with psych/bio colleagues 🌱🧠 (You can check out the paper I was soapboxing about here: onlinelibrary.wiley.com/doi/10.1111/...)

Thank you to David Macherel, Jose Gualberto and Hakim Mireau for organizing the 2024 ICPMB meeting and the special issue of Phys. Plant. And to Olivier Keech, Allan Rassumsson and Olivier Van Aken for organizing the 2022 ICPMB meeting where I first met Joanna and the seeds of this work germinated.

An exciting day! Our latest work is now out; we ask the question, are there any differences between plant mitochondria with and without mtDNA? 🌱 onlinelibrary.wiley.com/doi/10.1111/... (1/9)

Happy to share that this study is now published. Check it out! journals.plos.org/plosgenetics...

I'm thrilled to share that our story is now out in Science Advances! 🎉 We use quantitative imaging to map the mito central dogma, define translation hubs in the mitochondrial matrix, and show that they're replaced by Mitochondrial Stress Bodies (MSB) when mtRNA processing is perturbed 1/4

How do cells achieve an optimal mitochondrial distribution? Excited to share a piece of this puzzle: www.science.org/doi/10.1126/...

Nice to be back in sunny Münster to help out with the GoPMF Imaging Workshop 2025!

Congratulations to Rachael on this new story out now in PNAS! Delving into translational machinery retargeting across different plant species- plastid presence is the key 🗝️🔬🌱 it was a great experience helping out on the ‘scope for this project and working with some awesome scientists 🥳

Here's a mitochondrial "social network" (tracking encounters) emerging over time from their collective dynamics in a plant cell. This picture helps us understand their capacity to share and exchange biomolecules 🔬🌱🫂 Read more www.sciencedirect.com/science/arti...; pubmed.ncbi.nlm.nih.gov/34015261/

A revised version of our paper on Arabidopsis mitochondrial motion. Now using two methods of imaging mtDNA! Wonderful work by @chusteckisci.bsky.social "Running on empty: Mitochondria without mtDNA exhibit differential motility and connectivity." www.biorxiv.org/content/10.1...

So cool! Understanding how mtDNA regulates their movement inside cells will be possible with tools like these!

Hey blue skies- We have updated our latest #BioRxiv paper- We found that #mitochondria in #plants without mtDNA move and connect differently to those with mtDNA! Now featuring two different methods of measuring mtDNA and mitochondrial motility. Check it out: www.biorxiv.org/content/10.1...
