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

Plant shoot stem cells generate organs essential for food, feed, and biofuels. However, plant single-cell analyses struggled to capture these rare cells or to detect stem cell regulators like CLAVATA3 and WUSCHEL. Here, we dissected stem cell-enriched shoot tissues from maize and Arabidopsis for single-cell RNA sequencing (scRNA-seq), and we optimized protocols to recover thousands of CLAVATA3- and WUSCHEL-expressing cells. A cross-species comparison identified deeply conserved stem cell regulators. We also profiled maize stem cell mutants, validated candidate regulators with spatial transcriptomics, and confirmed their roles in shoot development. These include a family of RNA-binding protein genes and two families of sugar kinase genes. Finally, we show how coupling large-scale single-cell profiling with allelic variation analysis in diverse maize germplasm serves as a valuable resource for identifying stem cell regulators significantly associated with grain yield components. Our discoveries advance the study of shoot stem cells and open avenues for rational crop engineering.
