<i>Pseudomonas</i> sp. N5.12 Metabolites Formulated in AgNPs Enhance Plant Fitness and Metabolism Without Altering Soil Microbial Communities.

ABSTRACT: This study investigated the effects of metabolites from the beneficial bacteria Pseudomonas N5.12 formulated as silver nanoparticles (AgNPs) on tomato plants and soil microbial communities to explore the environmental safety of AgNPs for future applications in agriculture. AgNPs coated with bacterial metabolites exhibit biological activity that is dose-dependent, as shown by cytoskeleton alterations in Arabidopsis roots. The results show that N5.12-AgNPs can trigger beneficial effects on tomato plants, either when delivered through the leaves or roots, indicating the effectiveness of the metabolites formulated as NP. These effects consist of lowering oxidative stress metabolism and, therefore, improving plant resilience and increasing chlorophyll a and carotenoid content. The
