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 🧪 🌾

Mayank Sharma @mayankdu.bsky.social · 19h

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.

Let’s stare into the far red 🏮. A stunning tour-de-force of high-resolution #CryoEM by Gio, Bill, & company reveals how the machinery of photosynthesis redshifts itself so cyanobacteria can live on far red light, deep in the cracks of rocks or under microbial mats. #PlantScience 🧪 🧶🧬 🌾 🔬 🌍

Have you ever looked at the night sky and wondered if there’s a chlorophyll f in the reaction centre of Photosystem I from far-red light adapted cyanobacteria? 🦠

Well, we did (don’t judge) and the work that followed is now out as a First Release in @science.org

The discovery of chlorophyll f-containing photosystems, with their long-wavelength photochemistry, represented a distinct, low-energy paradigm for oxygenic photosynthesis. Structural studies on chloro...

The KEY🔑 to regulating Rubisco phase separation in the Chlamydomonas algal pyrenoid. Beautiful work by Shan He, @mjonikas.bsky.social, and friends. #PhaseSeparation #CO2 #PlantScience 🧪 🧶🧬 🌾 🌍

Martin Jonikas @mjonikas.bsky.social · 2d

Algal pyrenoids—condensates that mediate ~1/3 of Earth’s CO2 fixation—change size and number as cells divide. Our data suggest a simple control mechanism: a kinase that continuously ejects material from the condensate! ☀️🌍🔬💧 #Biophysics #Photosynthesis

✨Excited that the main project of my PhD is now available as a pre-print on #bioRxiv

Here, we used #CryoET to visualise mitochondrial proteostatic stress and together with SPA #CryoEM shed light into the functional cycle of the Hsp60:10 chaperone system. #TeamTomo

I think it has something to do with conservative lawmakers taking aim at liberal-leaning social media. See this announcement that my friend got. Did you get something similar? X is not affected by this law, and that place is swarming with misinformation and porn bots. No free speech = Hot Garbage 🔥🗑️

But there’s a curious loose end to this story. Scientists have been looking at PSII organization in thylakoids for over 50 years (including some really stunning freeze fracture 🔬😍). Sometimes PSII looks randomly oriented, and other times it forms extended 2D crystalline arrays in the membrane 💠

An interesting parallel: Rod outer-segment disk membranes are highly packed with a membrane protein (rhodopsin) 👁️, similar to the stacked domains of thylakoids (PSII-LHCII) 🌱. And isolation of disk membranes may cause rhodopsin to crystallize into 2D arrays 💠

Thanks Marcel! But don’t you mean the prettiest membranes on Earth? 😉. Golgi tried hard…. but thylakoids are the best 🌱🏆
