Pseudomonas enhances soil phosphorus bioavailability and maize seedling growth and affects soil microbial community.

Pseudomonas veronii 1416X3 and Pseudomonas sp. 1616X1 significantly increase soil phosphorus availability and promote maize seedling growth, altering soil microbial communities.

• Why it matters: Low bioavailability of soil phosphorus limits crop yields, and sustainable solutions are needed to reduce reliance on chemical fertilizers, supporting eco-friendly agriculture.
• What they did: Two phosphate-solubilizing Pseudomonas strains were isolated and used in pot experiments, measuring soil phosphorus, plant growth, and microbial community changes, alongside genome analysis.
• The result: Inoculation raised available phosphorus by over 1.3 times within four days, enhanced maize growth, and modulated microbial populations, revealing mechanisms for bio-phosphate fertilizer development.
