A GmNRF5a-GmCERK1-GmCAK1 module mediates chitin/chitosan-triggered immune response in soybean.
Article in Journal of integrative plant biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Chitin and its deacetylated derivative chitosan are the major components of fungal cell walls and are recognized by plant pattern-recognition receptors (PRRs) as pathogen-associated molecular patterns that induce innate immunity. Recognition of chitin oligosaccharide (CTOS) in Arabidopsis (Arabidopsis thaliana) and rice (Oryza sativa) requires the membrane-localized lysin-motif (LysM)-domain-containing receptors AtLYK5 and OsCEBiP, respectively. However, the mechanism underlying chitosan oligosaccharide (CSOS)-induced plant immunity remains unclear. In this study, we determined that CTOS and CSOS trigger immune responses and boost disease resistance in soybean (Glycine max) through the LysM-domain-containing protein GmNRF5a and its co-receptor GmCERK1. Surprisingly, both GmNFR5a and GmCERK1 bind directly to CTOS and CSOS, with distinct binding sites. The receptor-like kinase GmCAK1 acts downstream of GmCERK1 and is essential for CTOS/CSOS-mediated immune activation. Overall, these findings uncovered how soybean plants respond to CSOS and initiate immune signaling, demonstrating that soybean exploits shared immune sectors to transduce immune signals triggered by CTOS/CSOS, paving the way for the development of disease-resistant crops with broad-spectrum resistance.
