Microdomains heterogeneity in the thylakoid membrane proteins visualized by super-resolution microscopy.
Article in Photosynthetica, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The investigation of spatial heterogeneity within the thylakoid membrane (TM) proteins has gained increasing attention in photosynthetic research. The recent advances in live-cell imaging have allowed the identification of heterogeneous organisation of photosystems in small cyanobacterial cells. These sub-micrometre TM regions, termed microdomains in cyanobacteria, exhibit functional similarities with granal (Photosystem II dominant) and stromal (Photosystem I dominant) regions observed in TM of higher plants. This study delves into microdomain heterogeneity using super-resolution Airyscan-based microscopy enhancing resolution to approximately ~125 nm in x-y dimension. The new data reveal membrane areas rich in Photosystem I within the inner TM rings. Moreover, we identified analogous dynamics in the mobility of Photosystem II and phycobilisomes; countering earlier models that postulated differing mobility of these complexes. These novel findings thus hold significance for our understanding of photosynthesis regulation, particularly during state transitions.
