Overexpression of β-carboxysomes increases photosynthesis and growth in Synechocystis sp. PCC 6803.

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
Cyanobacteria are photoautotrophic cell factories capable of converting carbon dioxide into valuable chemicals. The rate-limiting step in photosynthesis is the enzymatic carbon fixation catalyzed by Rubisco. The carboxysome is a protein-based organelle that plays a central role in cyanobacterial carbon fixation. It consists of thousands of subunits, including hexameric and pentameric proteins, which form a shell to encapsulate the enzymes Rubisco and carbonic anhydrase. Here, we enhanced β-carboxysome biogenesis in Synechocystis sp. PCC 6803 by overexpressing a full or partial set of endogenous β-carboxysome components. Overexpression of carboxysome proteins altered protein stoichiometry, morphology, and cellular abundance of β-carboxysomes, as well as improved photosynthetic activities and cell growth. These findings indicate that targeted carboxysome overexpression enhances photosynthetic efficiency and growth of cyanobacteria under favorable conditions. This study provides a framework for engineering cyanobacterial chassis cells as microbial cell factories and carboxysome-based CO2-concentrating mechanisms in heterologous hosts, including crop plants, to improve photosynthetic productivity for sustainable bioproduction.
