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

Somatic embryogenesis is crucial for plant genetic engineering, yet the underlying mechanisms in cotton remain poorly understood. Here we present a telomere-to-telomere assembly of Jin668 and a high-quality assembly of YZ1, two highly regenerative allotetraploid cotton germplasms. The completion of the Jin668 genome enables characterization of ~30.1 Mb of centromeric regions invaded by centromeric retrotransposon of maize and Tekay retrotransposons, an ~8.1 Mb 5S rDNA array containing 25,190 copies and a ~75.1 Mb major 45S rDNA array with 8,131 copies. Comparative analyses of regenerative and recalcitrant genotypes reveal dynamic transcriptional patterns and chromatin accessibility during the initial regeneration process. A hierarchical gene regulatory network identifies AGL15 as a contributor to regeneration. Additionally, we demonstrate that genetic variation affects sgRNA target sites, while the Jin668 genome assembly reduces the risk of off-target effects in CRISPR-based genome editing. Together, the complete Jin668 genome reveals the complexity of genomic regions and cotton regeneration, and improves the precision of genome editing.
