What does the published scientific research say about Pseudomonas palmensis?

Pseudomonas palmensis is a recently described bacterial species — formally proposed as P. palmensis sp. nov. from type strain BBB001T, isolated from the rhizosphere of Nicotiana glauca in Las Palmas de Gran Canaria, Spain. Genomic analysis places it within the Pseudomonas brassicae group, differentiated from its closest relative by ANI, AAI, and digital DNA-DNA hybridization values below established species-level thresholds.

Two peer-reviewed articles in PubMed examine Pseudomonas palmensis in plant-input contexts. The species description paper (PMID 34489881) reported in vitro auxin and siderophore production by the type strain, improved iron nutrition and growth in iron-starved tomatoes, and up to 30% greater olive and oil yield under water-limiting conditions — findings the authors attribute to unique iron-metabolism genes identified in the BBB001T genome.

A second study (PMID 37620686) identified a Pseudomonas palmensis isolate (accession MT729782) from lentil rhizosphere soils in eastern India and reported increases in lentil shoot weight, root length, nodule count, and nitrogen and phosphorus uptake in pot culture. Together, the published Pseudomonas palmensis research positions it as a candidate plant growth-promoting rhizobacterium (PGPR) in the scientific literature, though no registered product or regulatory-approved label claim is established in the indexed data.
