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.

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

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 🧪 🌾

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
