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

Understanding the molecular basis of plant-pathogen interactions is critical for advancing crop protection strategies. Powdery mildew, caused by the obligate fungal pathogen Blumeria hordei (Bh), is a threat to barley production worldwide. We exploited time-course ATAC-Seq of barley and derived immune mutants infected with Bh to infer chromatin accessibility influenced by the genetic interactions of mildew locus a6 (Mla6), encoding a nucleotide binding leucine-rich repeat (NLR) immune receptor, and Blufensin1 (Bln1), a basal defense regulator. Sampling at 0, 16, 20, and 32 hours after inoculation captured key pathogen developmental stages representing fungal penetration and haustorial development, respectively. Validation of the dataset was accomplished by calculating general ATAC-Seq peak metrics and comparison with paired RNA-Seq data. ATAC-Seq and RNA-Seq results were correlated, highlighting in particular chromatin-mediated epistatic interactions, demonstrating that the dataset could provide insight into regulatory chromatin architecture. These results offer a valuable dataset for dissecting transcriptional networks involved in barley immune responses.
