The quantitative contribution of different Photosystem II compartments to non-photochemical quenching in Arabidopsis.
Article in Nature communications, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Excess excitation energy in the light-harvesting antenna of Photosystem II (PSII) can cause irreversible damage to the photosynthetic apparatus. In periods of high light intensity, a feedback mechanism known as non-photochemical quenching (NPQ) induces the formation of quenchers, which can safely dissipate excess excitation energy as heat. Although quenchers have been identified in more than one compartment of the PSII supercomplex, there is currently no quantitative description of the extent to which NPQ occurs at each of these locations. Here, we perform time-resolved fluorescence measurements on Arabidopsis thaliana WT and antenna mutants lacking LHCII trimers (koLHCII) and all peripheral antenna (Ch1lhcb5). By combining the results with those from steady-state fluorescence experiments, we are able to estimate the intrinsic rate of NPQ for each plant and each PSII compartment. It is concluded that more than 70% of quenching occurs in LHCII, less than 10% in the minor antenna, and the rest is associated with the PSII core.
