Uncovering the photosystem I assembly pathway in land plants.
Article in Nature plants, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Photosystem I (PSI) is one of two large pigment-protein complexes responsible for converting solar energy into chemical energy in all oxygenic photosynthetic organisms. The PSI supercomplex consists of the PSI core complex and peripheral light-harvesting complex I (LHCI) in eukaryotic photosynthetic organisms. However, how the PSI complex assembles in land plants is unknown. Here we describe PHOTOSYSTEM I BIOGENESIS FACTOR 8 (PBF8), a thylakoid-anchored protein in Arabidopsis thaliana that is required for PSI assembly. PBF8 regulates two key consecutive steps in this process, the building of two assembly intermediates comprising eight or nine subunits, by interacting with PSI core subunits. We identified putative PBF8 orthologues in charophytic algae and land plants but not in Cyanobacteria or Chlorophyta. Our data reveal the major PSI assembly pathway in land plants. Our findings suggest that novel assembly mechanisms evolved during plant terrestrialization to regulate PSI assembly, perhaps as a means to cope with terrestrial environments.
