Disease-resistant watermelon variety against Fusarium wilt by remodeling rhizosphere soil microenvironment.
Article in BMC microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundRhizosphere microorganisms and their interactions play a critical role in enhancing plant disease resistance. Here, we found that the disease severity of the resistant variety LW025 showed a decreasing trend with the increase in continuous cropping cycles. However, the mechanisms underlying the reduction in disease severity during the continuous cropping of the resistant watermelon variety LW025, particularly its relationship with the rhizosphere microbiome, remain unclear.
resultsIn this study, the transcriptome of different watermelon varieties after continuous planting in pathogen-containing and pathogen-free soils was analyzed. The results showed that only two genes expression showed significant differences in disease-resistant variety between healthy and diseased soils. Subsequently, we analyzed the differences of rhizosphere soil microbial communities after planting different watermelon varieties for three consecutive seasons, as well as the relationship between differential microorganisms and soil physiochemical properties and soil enzyme activity. The results demonstrated continuous cropping of the disease-resistant variety LW025 formed a rhizosphere microbiome different from the initial soil and susceptible variety. Specifically, fungal changes were primarily observed in Ascomycota and Chytridiomycota, while bacterial changes were mainly observed in Cyanobacteria and Gemmatimonadetes. The bacterial functions enriched in the rhizosphere of the resistant variety LW025 after continuous cropping were primarily associated with soil nitrogen cycling. Furthermore, the plant disease index showed a significant positive correlation with the available phosphorus and potassium content in the soil, while exhibiting a significant negative correlation with soil pH and catalase activity.
conclusionsOverall, the reduction in disease severity associated with continuous cropping of the disease-resistant variety LW025 was more closely related to changes in the rhizosphere microecological environment. This study explained the mechanism of the resistant variety LW025 against Fusarium infection, and provided new prospects for the development of technologies based on rhizosphere microecological environment modification to improve the resistance of watermelon to Fusarium wilt.
