What does the published scientific research say about Pseudomonas oryzihabitans?

Eight PubMed records index Pseudomonas oryzihabitans in a plant-input context, spanning rhizosphere isolates, endophytic strains, and co-inoculant trials across Arabidopsis, tomato, duckweed, Salicornia europaea, and Pyrus and Prunus rootstocks. The literature consistently characterizes it as a plant-growth-promoting bacterium (PGPB), studied from laboratory assays to greenhouse and aquaponic settings.

Root development is a recurring subject. Peer-reviewed research reports strain PGP01 increasing lateral root density in Arabidopsis through non-volatile signals and redox-dependent pathways involving ethylene, glutathione, and strigolactone, and raising root numbers in fruit-tree rootstocks in vitro while producing indole-3-acetic acid (IAA). A separate study on endophytic strain GDW1—isolated from pine—cites shoot, root, fresh-weight, and biomass improvements of up to 44%, 38%, 54%, and 59% in tomato, with transcriptomic links to auxin, gibberellin, and cytokinin signaling.
