Pm37 as a susceptible Sr22 allele confers resistance to wheat powdery mildew and leaf rust.
Article in Nature communications, 2026. 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
Wheat relatives harbour abundant variations that can be used for genetic improvement against diseases through complex domestication processes. Here, we report the isolation of the powdery mildew resistance gene Pm37 in common wheat through a strategy integrating map-based cloning, PacBio SMRT long-read genome sequencing, mutagenesis, barley stripe mosaic virus-induced gene silencing and stable transformation. Pm37 encodes a coiled-coil nucleotide-binding site leucine-rich repeat (CC-NBS-LRR) receptor. The cell death-inducing activity of PM37 in Nicotiana benthamiana is mainly mediated by its CC domain. De novo genome sequencing and haplotype analysis reveal that Pm37 may be derived from Triticum monococcum, and transferred into common wheat through T. timopheevii. Interestingly, Pm37 is a susceptible allele of the stem rust resistance locus Sr22, and also confers moderate resistance to leaf rust. Our findings identify a gene characterized by allelic variation-driven functional divergence in response to different wheat diseases.
