Organelles do NOT have a single uniform pH. And if you think they must, because “protons diffuse fast,” this paper is for you. A thread on why that assumption is wrong; and what we found instead. 🧵 1/n

My barley transcriptional network preprint is officially out! Started as my Bachelor’s thesis — now it’s online: doi.org/10.64898/202... Huge thanks to @itisalist.bsky.social, @daisybio.de, @huckelhovenr.bsky.social , Felix Hoheneder & Johannes Kersting for all their help and support!

Time for a rant. I help screen papers for @biorxiv-plants.bsky.social and I’m getting sick of seeing big names using the server as an advertisement platform rather than a place to share their science. What does this mean? (1/2)

Inaugural lecture to the faculty of Yasin Dagdas (@plantophagy.bsky.social) and Simon Wiegert (@simwieg.bsky.social) - bridging green and red biology.

😭1 badly timed bicycle accident and I’m out of the running to submit an ERC CoG grant this year, forcing me to wait almost a whole year to propose my idea. Why can’t the @erc.europa.eu emulate funders like the DFG and NIH and have rolling submissions for grants?

New preprint from our lab: Salicylic acid- induced alkalinization of the apoplast requires TMK1 and results in growth attenuation www.biorxiv.org/cgi/content/... Big thanks to all who contributed @guidogrossmann.bsky.social @julien-gronnier.bsky.social @kaltraxhelilaj.bsky.social

A fantastic critique of the new ERC Plus program. 100% agree. Please read:

How do cells adapt morphology to function? In a 🔥 preprint by @zjmaggiexu.bsky.social , with @dudinlab.bsky.social and @amyweeks.bsky.social , we identify a self-organizing single-cell morphology circuit that optimizes the feeding trap structure of the suctorian P. collini. 🧵 tinyurl.com/4k8nv926

Finally out in @nature.com! We uncovered a mechanistic framework for a general and conserved mRNA nuclear export pathway. www.nature.com/articles/s41.... 1/

I'm offering a PhD project together with Sarah McKim on temperature-controlled stomata formation within EASTBIO DTP www.findaphd.com/phds/project... #plantscience #plantscijobs Deadline 15 Feb. Please share/RP

New OA Article: "Cambium LBDs promote radial growth by regulating PLL-mediated pectin metabolism" rdcu.be/eP4mp LBD TFs in the cambium drive radial plant growth by regulating PECTATE LYASE-LIKE (PLL) enzymes that remodel cell wall pectin, promoting cell expansion.

By combining molecular genetics with cell-ablation experiments, we found that vascular cambium stem cells and xylem-identity cells form an interchangeable unit, a stem cell niche.

#ResearchCareers: Just finishing your #PhD and wondering if the DFG’s Walter Benjamin Programme is a #funding option for your next step in academia? Come and find out in our digital info talk on 14 October. No registration, the meeting link will be published here: ➡️ www.dfg.de/en/research-...

Ever wondered if analyzing your images by using intensity Z-projections impacts your data? Happy to announce my guest article in Microscopy & Analysis on that topic. It's a very short read but worth for everyone dealing with image analysis! buff.ly/KJ147tI #Microscopy #ZProjection #ImageAnalysis

PhD positions! For next year (deadline 15th april 2026, start date ~september 2026), we are looking for 15 PhD students for AGILE: "Advanced Training for Next Generation Scientists in Spatio-Temporal Imaging of Plant Cells" cordis.europa.eu/project/id/1... please repost! www.photobodies.com/about-6

The new lab website is online 🤩🥰 www.photobodies.com Please have a look 😊 So new and shiny, much info! Thanks Freddy for your contribution :)

Huge congratulations @jeremywyman.bsky.social @instmolplantsci.bsky.social for publishing the results of your masters thesis @annbot.bsky.social The work includes a new reconstruction of the Carboniferous isoetalean Oxroadia by the brilliant @palaeojules.bsky.social academic.oup.com/aob/advance-...

One alternative plant transformation tek I am so excited to try is the carbide whisker method. It uses thin silicon carbide fibers (nano-needles) to poke the crap out of plant tissue. Just adsorb DNA onto whiskers, add plant bits, and vortex for 1min. Obvs do not breathe in dust; respirator a MUST.

I am beyond thrilled (like the screaming and jumping type of thrilled) that my SNSF Starting Grant was funded. I will start my own lab @unibe.ch next year, studying succulent anatomy development and if and how this anatomy is required for efficient CAM photosynthesis in different Kalanchoë species 🌱

This Halloween, we have a spooky evolutionary story for you. The brainchild of @delaconcepcionjc.bsky.social, Nick Irwin and our fantastic collaborators is now out in @natplants.nature.com www.nature.com/articles/s41... Here’s why I love this work — and why I think you’ll enjoy it too. 👇
