BnDREB1 confers cadmium tolerance in ramie.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
Cadmium (Cd) is a toxic heavy metal whose contamination in soil threatens food safety, agricultural production, and human health. To date, phytoremediation is a low-cost and environmentally friendly method for eliminating Cd contamination. In this study, we report a gene from ramie (Boehmeria nivea) that encodes a dehydration responsive element binding (DREB) factor associated with plant tolerance to Cd, namely BnDREB1. The open reading frame of BnDREB1 comprises 873 bp encoding 290 amino acids and includes a characteristic AP2 domain. Its cloned promoter sequence contains various hormone and stress responsive elements. Quantitative RT-PCR analysis showed that BnDREB1 is expressed in different organs of ramie. Treatments with polyethylene glycol (PEG), abscisic acid (ABA), and Cd upregulated the expression of BnDREB1. Confocal microscopic analysis revealed that BnDREB1 is mainly localized in the nucleus. Overexpression of BnDREB1 in Arabidopsis thaliana increased the tolerance of transgenic plants to Cd, thereby protecting plant growth from its toxicity. Biochemical analysis revealed that overexpression of BnDREB1 reduced the levels of Cd induced malonaldehyde and hydrogen peroxide, inhibited the reduction of Cd caused soluble protein contents, increased the Cd accumulation, and enhanced Cd translocation in transgenic plants. Taken together, these findings suggest that BnDREB1 is an appropriate candidate gene for phytoremediation of Cd-contaminated soil .
