Pan-genome analysis of Morganella morganii reveals niche-specific selection of functional traits: friend or foe?

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
Morganella morganii exemplifies a typical case of an open pangenome, where genes move intra- and interspecies via horizontal gene transfer. Through pangenome analysis, the study maps three agriculture isolates; M. morganii with strong plant growth promoting (PGP) activity, along with 78 publicly available genomes from clinical, food, wastewater, and animal sources. The analysis showed 20,860 gene clusters with only 9.99% core genes and a discriminating distribution of 75.20% cloud genes across different niches. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis showed 33, 36, and 38 genes related to nutrient solubilization in M. morganii isolates HM01, HM02, and HM03, respectively. Chemotaxis genes, crucial for stress response, were most abundant in HM03 (30), followed by HM01 (17) and HM02 (27). Additionally, numerous biosynthetic gene clusters encoding antibacterial and antifungal metabolites were identified. Clinical and wastewater isolates harboured a higher number of mobile genetic element (MGE) linked antimicrobial resistance (AMR) genes that confer resistance to 15 antibiotic classes. These AMR genes were predominantly plasmid-borne and found to transfer in M. morganii from clinical pathogens such as E. coli and A. baumannii. This study indicates that habitat pressure creates the scenario for selection of functional traits which enables the ecosystem specific survival of M. morganii. Together, the present investigation provides important insight into the genomic diversity and remarkable PGP potential of M. morganii strains for sustainable agriculture. The pangenome analysis proposes that detailed investigation is needed to confirm their efficacy as PGP bacteria and to distinguish them from pathogenic strains.
