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

backgroundThe accumulation of cadmium (Cd) in ryegrass (Lolium multiflorum Lamk.) as a widely used pasture plant poses a serious risk to food safety. This study aimed to investigate the differences in phenotypes, physiology, and expression of metal transporters between four ryegrass genotypes (diploid/tetraploid and Cd-tolerant/sensitive).

resultsThe diploid/Cd-sensitive genotypes were found to uptake, accumulate, and translocate more Cd compared to the tetraploid/Cd-tolerant genotypes. Cd with more soluble components facilitated the transfer of Cd from root to shoot in the sensitive genotypes. Tetraploid and Cd-tolerant Chuansi No.1 accumulated less Cd in shoots but higher ratio in root cell wall, making it a promising model for studying the mechanisms of plant resistance to Cd stress. The complex regulatory system and dilution effect contributed to the lower uptake and accumulation of Cd in tetraploid genotypes. Moreover, tetraploid genotypes exhibited higher expression of genes that promoted Cd efflux, which could contribute to their lower Cd accumulation.

conclusionsOverall, this study sheds light on the physiological and transcriptional mechanisms of Cd uptake and accumulation by different polyploids, providing guidance for ryegrass breeding and soil improvement.
