Phyllosphere microbes in foxtail millet primarily affect quality by modulating coloration and bitter compounds.

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
backgroundCrop quality is influenced by crop-related factors such as varieties and metabolites, as well as by environmental conditions. Recent studies have shown the important role of rhizosphere microbes in determining crop quality and flavor, but the effects of phyllosphere (aboveground) microbes and metabolites remain unclear. Here, we examined the interaction between phyllosphere metabolites and the microbiome in three foxtail millet varieties with differing eating qualities: two high-eating-quality varieties (Yugu1, Jingu21) and one low-eating-quality variety (Daobaqi) in the field.
resultsThirteen metabolites were found to be depleted in the high-eating-quality varieties, four of which were identified as bitter compounds. These depleted metabolites were negatively correlated with the abundance of two microbial genera, Curtobacterium and Pseudomonas, enriched in the high-eating-quality foxtail millet panicles. Further analyses revealed that the abundance of these microbes was significantly associated with reduced bitterness and improved viscosity in the panicles. Additionally, synthetic microbial community experiments validated that these microbes enhanced foxtail millet quality by increasing the yellow coloration and reducing levels of bitter compounds.
conclusionsIn summary, the higher abundance of Curtobacterium and Pseudomonas in the panicles correlated with reduced bitter compounds and enhanced foxtail millet quality. This work provides new insights into the role of phyllosphere metabolites and microbiomes in determining crop quality.
