A PR1-Like Protein Stabilizes a Barwin-Like Protein to Enhance Wheat Resistance to Leaf Rust.
Article in Plant, cell & environment, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Pathogenesis-related 1 (PR1) proteins contribute to plant immunity through antimicrobial activity and the regulation of target protein stability and condensation. In wheat, TaPR1-2 has been widely used as a molecular marker of immune responses to rust fungi. However, it remains unclear whether other members of the PR1 family are involved in wheat resistance to leaf rust. Here, we show that the transcript levels of TaPR1-11 are induced following inoculation with Puccinia triticina (Pt). Overexpression of TaPR1-11 significantly enhanced wheat resistance to Pt, accompanied by reduced fungal growth, whereas TaPR1-11-RNAi wheat lines displayed increased susceptibility. TaPR1-11 physically interacts with TaPR4-1, a Barwin-like protein that also positively regulates wheat resistance to Pt. Further analysis revealed that TaPR1-11 stabilizes TaPR4-1 in vivo, while TaPR4-1 reciprocally promotes TaPR1-11 protein accumulation during Pt infection. Collectively, our findings identify a previously unreported PR1-PR4 protein partnership in wheat, showing that TaPR1-11 stabilizes TaPR4-1 to enhance resistance against Pt. This work expands current understanding of the molecular mechanisms by which PR1 proteins contribute to wheat defence responses.
