Regulation of excitation energy in Nannochloropsis photosystem II.
Article in Photosynthesis research, 2019. 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
Recently, we isolated a complex consisting of photosystem II (PSII) and light-harvesting complexes (LHCs) from Nannochloropsis granulata (Umetani et al. Photosynth Res 136:49-61, 2017). This complex contained stress-related protein, Lhcx, as a major component of LHC (Protein ID is Naga_100173g12.1), suggesting that non-photochemical quenching activities may be taking place in the PSII-LHC complex. In this study, we examined the energy transfer dynamics in the isolated LHCs and PSII-LHC complexes, and found substantial quenching capacity. In addition, the LHCs contained low-energy chlorophylls with fluorescence maxima at approximately 710 nm, which may enhance the quenching efficiency in the PSII-LHC. Delayed fluorescence analysis suggested that there was an approximately 50% reduction in energy trapping at the PSII reaction center in the PSII-LHC supercomplex under low-pH condition compared to neutral pH condition. Enhanced quenching may confer a survival advantage in the shallow-water habitat of Nannochloropsis.
