Pseudomonas koreensis boosts grass growth under nitrogen limitation by modulating plant nitrogen acquisition and metabolism

Summary

This article investigates how the plant growth-promoting bacterium Pseudomonas koreensis enhances growth in Brachypodium distachyon (a model grass species) under nitrogen-limited conditions. The research reveals that the bacterium modulates plant-encoded nitrogen acquisition systems and reorganizes metabolic pathways to improve plant performance despite low nitrogen availability. The study provides systems-level insights into plant-microbe interactions that could inform biological strategies to reduce mineral fertilizer inputs in agriculture while maintaining crop productivity.
