Multi-omics and field experiments reveal the mechanism of Pseudomonas palleroniana P6 promoting the growth and polyphyllins accumulation in Paris polyphylla.

ABSTRACT:

Background

Paris polyphylla (P. polyphylla), a medicinal herb valued in traditional Chinese medicine, struggles with slow growth rate and long maturation periods, hindering sustainable cultivation and commercial production-especially for polyphyllins, its key bioactive compounds. Although plant growth-promoting rhizobacteria (PGPR) have shown potential in enhancing crop productivity and secondary metabolite accumulation, their application in slow-growing medicinal plants like P. polyphylla remains underexplored.  RESULTS: In this study, 25 strains with inorganic phosphorus-dissolving, potassium-solubilizing and nitrogen-fixing abilities were isolated from the rhizosphere soil of P. polyphylla, mainly belonging to Bacillus, Pseudomonas, and Rhizobium. Among them, the strain Pseudomo
