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 🧪

The chloroplast ionome shines light on the dynamics of organellar iron homeostasis Loss of chloroplast iron (Fe) ferritin storage leads to Fe re-shuttling into the vacuole and reduced leaf tissue Fe content.

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...

Now online in its final version. Plz surf to doi.org/10.1111/tpj....

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 🧪 🌾

Thanks a lot Ben. 🙏😃

We propose a distinct mechanism of membrane remodeling in chloroplasts with resemblances to cytosolic ESCRT pathway. Kudos and congratulations to the first author and my first student Irem Yilmazer for all her hard work. And, big thanks to my mentor Prof. Zeeman for his continuous support. 🙏

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.

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!

Huge congratulations on this remarkable milestone—exciting times are ahead! 💫😀🍀

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

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:
