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

Cyperus rotundus, a globally distributed and highly competitive weed, has evolved herbicide resistance, posing a significant challenge to sustainable agriculture; however, the lack of genomic resources has limited comprehensive investigations into its resistance mechanisms. Here, we report a chromosome-level genome assembly of triploid C. rotundus (875.13 Mb across 165 chromosomes), which exhibits high synteny among haplotypes. Comparative analysis of six populations revealed that only a population from Changde, Hunan, China (designated R-HN) displayed dual resistance to glyphosate and glufosinate. In this population, high expression of the target-site resistance gene glutamine synthetase 2 (GS2) contributes to glufosinate resistance, whereas glyphosate resistance is predominantly mediated by non-target-site resistance (NTSR) mechanisms. By integrating transcriptomic profiling with yeast-based functional validation, we identified two NTSR genes, CrABCG15 and CrCASPL2C2, that confer glyphosate resistance. Collectively, this study provides a high-quality genomic resource for C. rotundus and advances our understanding of its genomic evolution and herbicide resistance mechanisms.
