The path effects of a bacterial signal compound on the microbiome of canola.

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
backgroundBacillin 201 has been shown to act as a biostimulant, it enhances seed germination and increases the biomass of soybean and canola plants. However, the mechanisms underlying these benefits, and their impacts on the plant-associated microbiome, remain unquantified. In this study, we investigated the causal effects of bacillin 20 on the bacterial communities associated with canola.
resultsWe conducted a field study with three different concentrations of bacillin 20 as seed treatment and foliar spray on canola cultivar InVigor L233P followed by a randomized complete block design in clay loam and sandy loam soils and investigated how bacillin 20 influences the structure and richness of bacterial communities across biotypes, including those in root tissues and rhizosphere soil. Our findings revealed that rhizosphere soil bacterial communities clustered closely in the studied clay loam soil. Bacterial alpha diversity did not respond significantly to bacillin 20 treatments, however, Rhizobiales bacteria become most abundant in the rhizosphere soil. Also, four bacteria- Rosemicrobium sp., Sphingomonas sp. and two unclassified Planctomycetes were identified as indicator species in the microbial communities from both clay-loam and sandy-loam soils. We analysed causal relationships between the effects of bacillin 20 and experimentally controlled factors affecting bacterial communities, such as those associated with root tissue, soil and treatment (bacillin 20) types. Some bacterial taxa—ASV55 (Candidatus Xiphinematobacter) were negatively affected by bacillin 20 foliar treatment, and ASV73 (unidentified Tepidisphaerales) by seed treatment.
conclusionOverall, our study revealed key explanatory variables influencing the effect of bacillin 20 on the bacterial communities associated with canola roots and rhizosphere soil. Although soil type (clay versus sandy loam) did not directly affect the bacterial communities, we found that bacillin 20 affected the canola root system associated microbiota. This shifts in the associated bacteria could be influenced by developmental stages, not by the treatment of bacillin 20 alone.
