Molecular mechanism of phototropin light signaling.
Review in Journal of plant research, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 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
Phototropin (phot) is a blue light (BL) receptor kinase involved in the BL responses of several species, ranging from green algae to higher plants. Phot converts BL signals from the environment into biochemical signals that trigger cellular responses. In phot, the LOV1 and LOV2 domains of the N-terminal region utilize BL for cyclic photoreactions and regulate C-terminal serine/threonine kinase (STK) activity. LOV2-STK peptides are the smallest functional unit of phot and are useful for understanding regulation mechanisms. The combined analysis of spectroscopy and STK activity assay in Arabidopsis phots suggests that the decay speed of the photo-intermediate S390 in LOV2 is one of the factors contributing to light sensitive kinase activity. LOV2 and STK are thought to be adjacent to each other in LOV2-STK with small angle scattering (SAXS). BL irradiation induces LOV2-STK elongation, resulting in LOV2 shifting away from STK. The N- and C-terminal lateral regions of LOV2, A'α-helix, Jα-helix, and A'α/Aβ gap are responsible for the propagation of the BL signal to STK via conformational changes. The comparison between LOV2-STK and full-length phot from Chlamydomonas suggests that LOV1 is directly adjacent to LOV2 in LOV2-STK; therefore, LOV1 may indirectly regulate STK. The molecular mechanism of phot is discussed.
