Optimal disk packing of chloroplasts in plant cells.

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
Photosynthesis is essential for ecosystem survival, but while plants require light, excessive exposure can damage cells. Chloroplasts, photosynthetic organelles, respond via self-organized motion within cells to optimize light absorption. These disk-shaped organelles must balance two competing needs: dense packing to enhance absorption under dim light and rapid spatial rearrangement to avoid damage from excess light. Using microscopy, we show that plant cell shape and chloroplast size achieve both goals: dense monolayer packing for optimal absorption in low light and sidewall packing for light avoidance. We present a theoretical model using random close packing simulations of polydispersed hard disks in rectangular boxes and find optimal cell shapes that match plant cell measurements. Our findings highlight how particle packing principles under confinement enable light adaptation in plants, offering insights into organelle organization under confinement, a physical challenge relevant across biological systems.
