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

Crop genetic improvement requires balancing complex tradeoffs caused by gene pleiotropy and linkage drags, as exemplified by IPA1 (Ideal Plant Architecture 1), a typical pleiotropic gene in rice that increases grains per panicle but reduces tillers. In this study, we identified a 54-base pair cis-regulatory region in IPA1 via a tiling-deletion-based CRISPR-Cas9 screen that, when deleted, resolves the tradeoff between grains per panicle and tiller number, leading to substantially enhanced grain yield per plant. Mechanistic studies revealed that the deleted fragment is a target site for the transcription factor An-1 to repress IPA1 expression in panicles and roots. Targeting gene regulatory regions should help dissect tradeoff effects and provide a rich source of targets for breeding complementary beneficial traits.
