Another brutal day for us. Patient safety investigation processes have to change. They are so re-traumatising and also add new trauma to exhausted, devastated parents. I'm doing it for you, Isabelle, but all I want is to cuddle you and feel your curls on my face again. #psii

🌽📊 RESEARCH 🌽📊

With GWAS, Ali et al. identified high confidence signals associated with chlorophyll, ΦPSII, ΦNPQ, & qL variation. Arabidopsis ortholog insertion alleles of maize candidates had photosynthesis-related phenotypes in line with the GWAS.

Great preprint by Upadhyaya et al. (2025) on using a #multiomics approach to study #PlantTOR signaling in the unicellular green alga #Chromochloris zofingiensis, particularly showing the upregulation of #AminoAcid biosynthesis pathways during TOR inhibition with AZD8055.

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 💠

We also observed that PSII concentration was uniform throughout each granum, irrespective of distance from the margin. Thus, we propose a simple two-domain model of thylakoid organization in green algae and plants. And yes, we speculate about domain #PhaseSeparation. I await your hate mail 📬🤗

The talented @lorenzlamm.bsky.social (joint PhD w/ @tingyingpeng.bsky.social) developed #MemBrain 🤖🧠software to automatically segment the thylakoid membranes and localize all the photosystem II (PSII) complexes embedded within them. Let’s get analyzing!👨‍💻🤓

🦠🧠 MemBrain update! 🧠🦠
We’ve updated our preprint! It now covers the full MemBrain v2 pipeline for end-to-end membrane analysis in #CryoET: segmentation, particle picking, and spatial statistics.

For decades, the idea has persisted that grana margins have a distinct protein composition and provide a zone where PSI & PSII can intermix. However, our "membranograms" revealed strict lateral heterogeneity between PSI & PSII at the margins, just like we previously observed in green algae 🟦🟨

Been forever since I played. Rune ran out of MP, so I tp'd out. Then went I got back to the same spot, I forgot there was a recharge sigil on the ground in the next room lol fml

This ain't as bad as the Green Dam from PSII at least. The dams always make me dread when I replay through them

Repression of PhANGs by NACs was also required for the downregulation of photosynthesis during Pseudomonas infection, confirmed by immunoblots on PhANGs and PSII activity measurments (13/18)

absolutely, this OST is really great, the opening, dungeon themes, overworld themes are all excellent! PSII has the better battle theme tho

Unfortunately, I’ve never played PSO, but some friends and I have been talking about it the past few nights. They were filling me in about the story, and I’ve been drawing parallels between what they’ve shared about PSO and what I recall about PSII!

## 연구 자료: 탄소 동화 작용 효율 증대를 위한 광계 II 반응 중심의 생체 모방 시스템 개발

**연구 배경** 지구의 생물학적 순환에서 가장 중요한 과정 중 하나는 광합성이다. 특히, 광계 II(Photosystem II, PSII)는 물 분해를 통해 산소를 생성하고 전자를 전달하여 광합성의 초기 단계를 수행하는 핵심 단백질 복합체이다. PSII의 효율적인 작동은 지구 생태계의 유지뿐만 아니라, 지속 가능한 에너지 생산을 위한 잠재력으로도 이어진다. 본 연구는 PSII의 자연적인 효율성을 모방하고 개선하여, 탄소 동화 작용…
