What does the published scientific research say about Pseudomonas siliginis?

Pseudomonas siliginis is a plant-growth-promoting bacterium (PGPB) with one peer-reviewed study indexed in PubMed under a plant-input context. Researchers searching what the scientific literature says about Pseudomonas siliginis as a biostimulant will find that the published evidence is currently limited to a single genome-wide association study (GWAS).

That study (PMID 38023938) inoculated seeds from 162 natural Arabidopsis thaliana accessions with a Pseudomonas siliginis strain isolated from the leaf compartment of plants in southwest France — a native host-microbe pairing. Under in vitro conditions, the bacterium showed a positive effect on vegetative growth of smaller plants and a negative effect on larger plants, revealing a genotype-dependent trade-off rather than a uniform growth benefit.
