Hot off the press, first PI paper 🎉. Reporting a novel protein (VIA1) involved in thylakoid membrane biogenesis. VIA1 (similar to ESCRT-II) and bind to chloroplast ESCRT-III (VIPP1). Showing a direct role of VIPP1 in thylakoid biogenesis. @cp-cellreports.bsky.social tinyurl.com/msrepdna

Somewhere, over the rainbow 🌈 (at the @biozentrum.unibas.ch), Sofie & Wojciech discovered how special cyanobacteria adapt to far-red light 🚨 by completely remodeling their photosynthetic proteins and membranes 🌱. An exquisite #TeamTomo study that spans scales and introduces hyperspectral CLEM. 🌎🌊🌾🔬🧪

Happy to see this one finally in print! A fantastic story led by Daan and the team. Congrats to everyone involved! #plantscience

New PEC story 🌱 led by PhD cand Susi with amazing collabs Grimm, Hause & Robatzek labs! We patch-clamped isolated plastids to show that PECs mediate rapid cation flux across the IE. PECs relay Ca²⁺ signals into plastids & link Ca²⁺ to JA-mediated defense. #plantscience www.pnas.org/doi/10.1073/...

Congratulations to Susanne, Henning @kunzlab.bsky.social and the team on this exciting new publication in @pnas.org 🎉🌱 Insightful work connecting plastid ion channels, Ca+ signalling, hormone biology, and plant immunity! 👏 doi.org/10.1073/pnas...

Dry seeds are not waiting to build mitochondria—they come pre-packaged with cristae and full respiratory complexes. ⚡️🌱🌱🌱 Check out the updated growth-and-division model in @currentbiology.bsky.social doi.org/10.1016/j.cu...

Hi #plantscience peeps, please check out our revised manuscript version under: www.biorxiv.org/content/10.6...

New preprint 🚀 ❄️ We developed Autogrid-compatible HPF planchettes that enable direct freezing of clipped EM grids and streamline integration with cryo-FIB workflows ✔️ improved grid stability ✔️ reduced handling ✔️ robust vitrification (🦠 🧫 🧠) A step toward routine HPF for complex samples #teamtomo

New paper out from the Synoxys lab! We asked an important question: what if plants sensed oxygen like animals do? what if we swapped the O2 sensing across? We built the system to find out. 🧵 www.nature.com/articles/s41... #plantscience @syno2xis.bsky.social @beagiuntoli.bsky.social @biology.ox.ac.uk

At long last, the Chlamy chloroplast ribosome hat 🎩 (now renamed the arm 💪) is here to say hello👋! We first spotted this extended structure in green algae a decade ago, and @florentwaltz.bsky.social did beautiful work bringing it into focus! #CryoEM ❄️ #TeamTomo 🔬 #PlantScience 🌾 #ProtistsOnSky 🧪

Plz read our study by @lmumuenchen.bsky.social PhD cand. Lorenz. He describes chloroplast ionomes for several 🌱species & shows how plastid iron can be massively increased. Terrific help by peers from @ruhr-uni-bochum.de, @mizzouid.bsky.social and @uni-saarland.de academic.oup.com/plcell/artic...

Plz check out our preprint in which we investigate the role of KEA1 in #chlamy, a monoplastid algae. KO mutant vs WT comparison across the green linage reveals conserved but also novel insights in part linked to the mono plastid bottleneck. Thx to many terrific collabs 👇 doi.org/10.64898/202...

Hey #TeamTomo …would you like to try some 🍦ICECREAM!? Our @unibas.ch colleagues over at the @ivandokmanic.bsky.social lab have developed a stunningly effective tool to de-noise and de-wedge your tomograms. The contrast and details will give you brain freeze! 🍨❄️🤯 Please try, we need feedback 🧪🧶🧬🔬

So, we all know that VIPP1 (the Very Important Protein in Plants) is the "photosynthetic ESCRT-III", required for the biogenesis and maintenance of light-harvesting thylakoids. But what about ESCRT-II, you say? ...Meet VIA1! Congrats @mayankdu.bsky.social on your lab's first paper! #PlantScience 🧪 🌾

New work from the Synoxys lab! About how does a plant’s habitat, whether growing in water, drylands, or typical soils, shape the evolution of its oxygen-sensing machinery. Indulge! #plantscience #ISPLORE2025JP

Honoured & excited that ‘Breathing Underground’ has been funded by the ERC! This will let me explore one of the most fundamental questions of plant life: how roots breathe underground? @erc.europa.eu

It is not often that you see shiny flowers but these water-buttercup, Ranunculus lingua, are definitely shiny. They thank this to a unique and rare combination of traits. 🧵1/3

Outstanding work by @anyalb.bsky.social in my lab - she targeted enzymes to synthetic biomolecular condensates in plants and showed increases in metabolic pathway activity, likely due to protection of the introduced enzymes from proteolysis #PlantScience onlinelibrary.wiley.com/doi/10.1111/...

Preprint alert, please share!! With our new study, we engineered an orthogonal hypoxia-responsive system in plants inspired by mammalian HIF protein degradation. We demonstrated that this system could control protein stability and activity, enabling modulation of Oxygen sensing outputs. Here's how:
