Transcriptional and epigenomic changes in response to polyethylene glycol-triggered osmotic stress in Brassica napus L.
Article in Journal of experimental botany, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Drought hinders growth, development, and productivity of higher plants. While the physiological and molecular background of plant responses to drought has been extensively studied, the role of post-translational modifications of histones or DNA methylation in response to dehydration remains largely elusive. In this study, we deciphered genome-wide changes in transcriptome and histone modifications in response to dehydration in rapeseed (Brassica napus L.). High-throughput transcript profiling (RNA-seq) and ChIP followed by sequencing (ChIP-seq) of polyethylene glycol (PEG)-treated rapeseed plants revealed genome-scale changes in transcription and histone methylation patterns, specifically in histone H3 lysine 4 trimethylation (H3K4me3) and histone H3 tri-methylated lysine 27 (H3K27me3) sites. We have identified gene sets with altered transcript profiles as well as histone methylation marks in response to osmotic stress. Several proline biosynthesis regulatory genes coding for Delta 1-Pyrroline-5-Carboxylate Synthetases (P5CS) displayed changes in H3K4me3 and/or H3K36me3 enrichment post-PEG treatment. Targeted bisulfite sequencing further identified stress-dependent gene body DNA methylation in one of the BnP5CSA gene copies that correlates with its stress-induced activation. By integrating physiological, transcriptional, and epigenomic data, our study contributes to a better understanding of the drought response control in crop plants.
