In situ visualization of glycoside hydrolase family 92 genes in marine flavobacteria.
Article in ISME communications, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Gene clusters rich in carbohydrate-active enzymes within Flavobacteriia genera provide a competitiveness for their hosts to degrade diatom-derived polysaccharides. One such widely distributed polysaccharide is glucuronomannan, a main cell wall component of diatoms. A conserved gene cluster putatively degrading glucuronomannan was found previously among various flavobacterial taxa in marine metagenomes. Here, we aimed to visualize two glycoside hydrolase family 92 genes coding for α-mannosidases with fluorescently-labeled polynucleotide probes using direct-geneFISH. Reliable in situ localization of single-copy genes was achieved with an efficiency up to 74% not only in the flavobacterial strains Polaribacter Hel1_33_49 and Formosa Hel1_33_131 but also in planktonic samples from the North Sea. In combination with high-resolution microscopy, direct-geneFISH gave visual evidence of the contrasting lifestyles of closely related Polaribacter species in those samples and allowed for the determination of gene distribution among attached and free-living cells. We also detected highly similar GH92 genes in yet unidentified taxa by broadening probe specificities, enabling a visualization of the functional trait in subpopulations across the borders of species and genera. Such a quantitative insight into the niche separation of flavobacterial taxa complements our understanding of the ecology of polysaccharide-degrading bacteria beyond omics-based techniques on a single-cell level.
