1 · What the graph read from it

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.

2 · The registry

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

Circadian clocks enable organisms to adapt to a 24 h diurnal cycle and anticipate rhythmic changes in the environment. The Arabidopsis central oscillator contains three genes encoding core clock components. CIRCADIAN CLOCK ASSOCIATED 1 (CCA1)/LATE ELONGATED HYPOCOTYL (LHY) and TIMING OF CAB EXPRESSION 1 (TOC1) reciprocally repress genes encoding each other and are critical for the generation of circadian rhythms controlling many clock outputs. A precise regulation of transcriptional events is, therefore, essential for proper circadian function. Here, we investigated histone 3 (H3) tail modifications of CCA1, LHY and TOC1 under various conditions. We found specific association of only H3K4Me3 and H3K9/14Ac with the translational start site of these three genes. These H3 marks were enriched at circadian time points of their increased transcription at different photoperiods and under free-running conditions, suggesting circadian regulation of H3 modifications. Analysis of clock-compromised CCA1-overexpressing lines provided evidence that light/dark photoperiods signal the establishment of these chromatin changes which are gated by the clock.
