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/...
Model of chloroplast Ca²⁺-mediated priming: after a stress trigger, plants show a larger stromal Ca²⁺ signal via PEC1, boosting OPDA and JA production and enhancing defense gene expression compared to baseline

ESCRT-III assembles around mis-segregated DNA to protect genome stability - Nature Structural & Molecular Biology
The authors show that persistent ultrafine DNA bridges become coated by membranes and the ESCRT-III proteins CHMP1B and IST1, which protect the genome within from damage.

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...

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.

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 🧪 🌾

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. 🙏
