Dual activation of soybean resistance against Phytophthora sojae by pectin lyase and degraded pectin oligosaccharides.
Article in Science China. Life sciences, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Phytophthora pathogens secrete numerous apoplastic effectors to manipulate host immunity. Herein, we identified a polysaccharide lyase 1 protein, PsPL1, which acts as an essential virulence factor of P. sojae infection in soybean. However, the overexpression of PsPL1 in P. sojae reduced infection and triggered enhanced immune responses in soybean. PsPL1 exhibited pectin lyase activity and degraded plant pectin to generate pectin oligosaccharides (POSs) with a polymerization degree of 3-14, exhibiting different levels of acetylation and methylation modifications. PsPL1 and the degraded pectin products triggered immune responses in soybean and different Solanaceous plants. The PsPL1-triggered immune responses required RSPL1, a membrane-localized leucine-rich repeat receptor-like protein, which is essential for Phytophthora resistance. Conversely, the PsPL1-degraded product-triggered immune responses depended on the membrane-localized lysin motif receptor-like kinase CERK1. This study reveals that the pectin lyase exhibits a dual immunogenic role during P. sojae infection, which activates plant resistance through different immune receptors and provides novel insights into the function of pectin lyase in host-pathogen interactions.
