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

Grain weight is one of the critical determinants of wheat (Triticum aestivum L.) yield, and understanding its genetic and molecular mechanisms is essential for improving crop productivity. Here, we find that TaSG-D1, which encodes an STKc-GSK3 kinase, negatively regulates grain weight. TaSG-D1 interacts with and phosphorylates TaGAMyb to reduce its degradation. Overexpression of TaGAMyb results in decreased grain length and weight, whereas its knockout increases both agronomic traits in wheat. Further investigation reveals that TaGAMyb directly activates the expression of TaCKX2.2.1, a negative regulator of grain development. Transcriptome profiling shows differential expression of TaCKX2.2.1 in 15-DAP grain of WT and TaGAMyb knockout lines, ultimately leading to a decreased concentration of active cytokinin in grains. Taken together, our findings demonstrate that TaSG-D1 negatively regulates grain development by increasing the protein abundance of transcription factor TaGAMyb, which in turn promotes the expression of downstream gene TaCKX2.2.1, a key regulator of cytokinin signaling.
