What does the published scientific research say about Pseudomonas striata?

Three PubMed abstracts address Pseudomonas striata in agricultural contexts, characterizing it as a phosphate-solubilizing microorganism (PSM) and plant growth-promoting rhizobacterium (PGPR). Growers and formulators searching for Pseudomonas striata PGPR or Pseudomonas striata phosphate solubilization will find peer-reviewed evidence spanning glasshouse trials, genotype studies, and biofilm research.

Glasshouse work with pea (PMID 16114471) reported that P. striata inoculation increased plant transpiration and growth and reduced galling and multiplication of the root-knot nematode Meloidogyne incognita. Combined inoculation with Rhizobium sp. amplified both effects, with the strongest nematode suppression observed in 40% fly-ash-amended soil.

A genotype study (PMID 23572916) confirmed that P. striata can colonize plant roots as an endophyte, with colonization rates varying significantly by maize and mungbean cultivar. Co-inoculation with the symbiotic fungus Piriformospora indica enhanced endophytic establishment in both crops, indicating that host genotype and microbial partnerships shape colonization outcomes.

A biofilm study (PMID 21448713) paired P. striata with the cyanobacterium Anabaena torulosa and documented enhanced population counts alongside traits including phosphate solubilization and IAA production — cited in peer-reviewed research as attributes relevant to sustainable inoculant design.
